Installation and maintenance of double roll extrusion granulator in fertilizer production line

The double roller press granulator is the key equipment for compound fertilizer granulation. It has advanced technology, reasonable design, compact structure, low energy consumption, and is matched with corresponding equipment to form a small production line, which can form a certain continuous production and mechanized production. , No drying, room temperature production, capacity, product quality meet the technical requirements of compound fertilizer, it is the latest product of energy saving and consumption reduction of npk production line of high, medium and low concentration special compound fertilizer and compound fertilizer industry.

The double roller granulator has the characteristics of low energy consumption, high energy saving, low investment, simple operation, and pollution-free equipment emissions. The distance between the pressure rollers should not be too small or too large, and should be adjusted within the specified range. Secondly, the pressure cover on the bearing seat side should be avoided to be too loose or too tight, which will cause the shaft rollers to shift.

1. Uniform feeding: Since the surface of the biological fertilizer granulator is friction material and direct force, in the npk manufacturing process, when the roller surface is worn, the friction and back pressure of the material cannot be ignored. This force requires higher quality roll skins, lower mass wear rates, and lower mass wear rates. If the feeding is not uniform, the center of the parallel bar axis of the biofertilizer granulator is parallel to the surface of the roller sheet, the feeding at one end and the feeding at the other end will cause uneven force at both ends of the roller, thereby increasing the friction between the roller and the material , resulting in roller wear.

2. Material pH: Since the roller cover of the biological fertilizer granulator is made of stainless steel, it has a strong response to the pH of the material. Due to the lack of moisture and alkalinity of the material, it will cause acid and alkali corrosion on the surface of the roll and damage the roll. If the operating procedure does not work, the gap between the rollers will not be properly adjusted and contain impurities such as iron and sulfur. The color phase can seriously damage the roll surface.

How much does it cost for a corganic fertilizer equipment with an annual output of 40000 tons?

The investment required for producing organic fertilizer varies depending on the scale, and the equipment of the entire organic fertilizer production line is not fixed. It is determined based on the on-site site and material output.

Different types of feces require different types and models of equipment. Powdered fertilizers and granular fertilizers require different equipment for different processes. So the investment amount for the entire organic fertilizer equipment production line is not fixed, there are highs and lows, and the difference in investment amount between small and large production lines is even more significant.

The investment amount for the complete set of equipment on a 40000 ton organic fertilizer production line is generally between 400000 to 2 million yuan. Including organic fertilizer flipping machines, animal manure crushers, conveyors and other equipment, it is necessary to add a complete set of equipment such as forklifts, horizontal mixers, organic fertilizer granulators, screening machines, weighing and packaging machines.

To configure a complete annual production of 40000 tons of organic fertilizer equipment, the following are required:

Dehydration machine – fermentation flipping machine – crusher – screening machine – mixer – granulator – dryer – cooling machine – screening machine – particle packaging machine. During the production process, there is also a need for forklift feeding and conveying equipment, and different equipment should be added according to different needs.

The larger the output, the greater the required equipment investment amount. However, these are not fixed and unchanging. Different types of feces, varying moisture content, or other organic waste materials such as various crop straw, sludge, processing waste (sugar residue, wine lees, vinegar residue, tofu residue, etc.) may require slightly different equipment.

In terms of ecological environment, the use of organic fertilizer can effectively solve the pollution caused by organic waste in industries such as animal husbandry and food processing, improve the safety and quality of agricultural products, and effectively improve the ecological environment;

In terms of crop production, China is a major agricultural country. Strengthening the recycling of waste to generate new energy and restore it to crop production can greatly save costs and investments. Organic fertilizer production equipment greatly saves the cost of producing organic fertilizers and other products, improves production efficiency, and ensures meeting the needs of a wide range of users. The emergence of organic fertilizer production lines is in line with market demand, and the development prospects of the market are immeasurable.

Organic fertilizer equipment and process flow required for processing fertilizers in cattle farms

The processing of organic fertilizer in cattle farms is a very important process. It can convert organic waste such as cow manure generated during the breeding process into efficient fertilizers, which can not only solve environmental problems but also provide sustainable nutritional supply for agricultural production.

In the process of organic fertilizer processing in cattle farms, equipment and process flow are crucial. Firstly, it is necessary to choose organic fertilizer processing equipment that is suitable for the scale and type of cattle farm, such as composting equipment and fermentation equipment. Composting equipment is mainly used to stack cow manure in layers, creating an environment for oxygen circulation and microbial reactions; Fermentation equipment can promote the decomposition and conversion of organic waste by controlling parameters such as temperature, humidity, and ventilation.

In terms of process flow, generally speaking, the processing of organic fertilizer in cattle farms can be divided into three stages: pre-treatment, fermentation, and post-treatment. The pre-treatment stage involves crushing and sieving cow manure to facilitate subsequent fermentation; The fermentation stage involves mixing pre treated cow manure with other organic waste, and then using the action of microorganisms to carry out fermentation reactions; The post-processing stage involves drying, crushing, and packaging the fermented organic fertilizer for storage and sales purposes.

Production line configuration of organic fertilizer equipment in cattle farms:

Production line equipment for powdered cow manure organic fertilizer: flipper (used for composting process) – vertical crusher (crushing larger blocks in organic fertilizer) – screening machine (screening out non compliant organic fertilizer and returning it) – batching machine (adding other required nutrients to organic fertilizer in a certain proportion, which is an optional device) – horizontal mixer (mixing different materials evenly and using it in combination with batching machine) – single bucket packaging machine (used for quantitative packaging of finished organic fertilizer)

Equipment for granular cow manure organic fertilizer production line: tipping machine – vertical crusher – drum screening machine (optional here) – batching machine and horizontal mixer (used in combination, belonging to optional equipment) – disc granulator – dryer and cooling machine – drum screening machine – round throwing machine (optional) – coating machine (optional) – single bucket packaging machine.

Equipment operation steps of organic fertilizer production line for chicken manure processing

The complete set of chicken manure processing organic fertilizer production line products are made from fresh chicken manure, pig manure, sheep manure, cow manure and other livestock and poultry, as well as straw, sludge, etc., as the main raw materials, without any chemical components. So how to operate an organic fertilizer production line to produce fertilizer?

The equipment operation steps of the organic fertilizer production line for chicken manure processing:

1. Preparation work:

Weigh and divide the chicken manure and livestock manure (with a moisture content of about 70%) that needs to be processed; Prepare BM bacterial agents. Mix animal manure and BM bacterial strains in a weight ratio of 1:10000, then stir 2-3 times. The moisture content of the stirred fermented product should be controlled between 55% -60% to achieve the effect of holding it in a ball and letting it go before dispersing. After 10-15 days of stacking and fermentation, it meets the standards of pollution-free and organic fertilizer in China, and can be used as a base fertilizer.

2. The key points and steps of fermenting livestock and poultry manure in organic fertilizer production line:

Step 1: Mix the fermentation agent evenly: Add 1 to 1.5 tons of dry chicken manure (about 2.5-3.5 tons of fresh chicken manure) and 1 kilogram of chicken manure fermentation agent. For each kilogram of fermentation agent, add an average of 5-10 kilograms of rice bran, corn, and bran. Stir well and sprinkle into the prepared materials for better results.

Step 2, Adjusting the Carbon to Nitrogen Ratio: The carbon to nitrogen ratio of the fermented fertilizer should be maintained at 25-30:1, and the pH should be adjusted to 6-8 (pH). Due to the high carbon to nitrogen ratio of chicken manure, some straw, rice straw, mushroom residue, etc. should be added during fermentation.

Step 3: Adjust the moisture content of chicken manure: During the fermentation process of organic fertilizer, it is very important to determine whether the moisture content is suitable. It should not be too high or too low, and should be maintained at 60-65%. The judgment method is to tightly grasp a handful of material, see watermarks on the fingertips but do not drip, and it is advisable to scatter on the ground.

Step 4: Chicken manure pile construction: When making a fermentation pile, it should not be too small or too short, as it will affect fermentation. The height is generally around 1.5 meters, the width is about 2 meters, and the pile with a length of 2-4 meters or more has a better fermentation effect.

Step 5, Mixing and Ventilation: Fermentation aids are aerobic microorganisms, so oxygen supply measures should be increased during the fermentation process to achieve mixing, frequent flipping, and ventilation, otherwise anaerobic fermentation will affect the fermentation effect of the materials.

Step 6, Fermentation completion: Generally, after 48 hours of chicken manure accumulation, the temperature will rise to 50-60 ℃, and on the third day it can reach 65 ℃ or above. Flip over at this high temperature once. In general, there will be 2-3 times of high temperature above 65 ℃ during the fermentation process. Flip over 2-3 times to complete the fermentation. Normally, fermentation can be completed in about a week, allowing the material to completely deodorize, ferment and mature, sterilize and kill insects.

3. Organic fertilizer technology for chicken manure fermentation

After being fermented with livestock manure fermentation agents, the fertilizer efficiency of livestock manure is better, it is safer and more convenient to use, and can also improve the utilization rate of chemical fertilizers. Not only chicken manure can ferment organic fertilizer, but various animal manure, straw, fallen leaves, bark, sawdust, etc. can also ferment organic fertilizer, and the fermentation method is basically the same. Finally, I would like to remind everyone that no matter what materials are used to ferment organic fertilizers, it is important to control the moisture content, otherwise the success will be in vain.

How to use fertilizer production lines to convert pig manure into organic fertilizer?

With the strengthening of the national environmental protection policy, the use of organic fertilizer equipment can meet the regulations on the treatment of livestock and poultry manure in the breeding industry. Laissez-faire accumulation of pig manure is very harmful, especially on medium and large pig farms. The pig manure deposition that has not been solved by the pig manure dryer will not seriously pollute the surrounding environment and cause great harm to the natural environment of pigs.

The organic fertilizer production line is imperative. The use of the organic fertilizer production line can efficiently convert manure into organic fertilizer with higher value and utilization. The organic fertilizer production line generally includes: fermentation stacker, pulverizer, screening machine, mixing mixer, stock transfer machine ,rotary drum granulator, dryers, coolers, screening machines, packaging machines, forklifts, etc.

In the production process of pig manure organic fertilizer, the pig manure organic fertilizer production line mainly includes two parts: fermentation and granulation. Since the new type of pig manure contains harmful substances, its shape cannot become a product. The purpose of pig manure fermentation is to make it harmless and make it a fertilizer with a high proportion of soil organic matter. Fermented pig manure is soft and tasteless. It can be processed into powder or granular organic fertilizer, and finally sold according to the outer packaging market of automatic packaging machine, which is also a part of organic fertilizer production.

 The production of organic fertilizer is based on the establishment of different processing techniques and different mechanical equipment. It is divided into powdered and granular organic fertilizers. In contrast, the powdered production process is relatively simple and the investment in machinery and equipment is small; the granular fertilizer processing technology is complex, the investment in production equipment projects is large, and granulators and drying equipment are added. But in terms of the sales market, granular fertilizers occupy the popular sales market and are more convenient than powder organic fertilizers.

Our company, Zhengzhou Huaqiang, is a professional organic fertilizer equipment manufacturer, including npk fertilizer manufacturing process, organic fertilizer production line and supporting organic fertilizer equipment. Welcome to consult.

The workflow and equipment characteristics of manure processing organic fertilizer equipment

The equipment for processing feces into organic fertilizer can use a sheep manure treatment machine to first pump the sheep manure and other feces from the fecal toilet into the equipment. After dehydration by the equipment, the moisture content after treatment is about 40%. Crops such as straw and rice bran (including N \ P \ K) can also be used as fillers. Then, biological bacterial agents can be sprinkled, and 1KG of bacterial agents mixed with 20KG of water are transported into the raw materials, which can ferment 1 ton of raw materials. Flip and toss once every 1-2 days, usually 7-10 days until fully decomposed.

What is the workflow of the equipment for processing feces into organic fertilizer?

1、 Mix sheep manure with an appropriate amount of straw powder, and the amount to be added depends on the moisture content of the sheep manure. Generally, fermentation requires a moisture content of 45%, which means kneading it into a ball with your hands, seeing water between your fingers, but not dripping. Release your hand and dissolve it immediately. Then add corn flour and bacterial strains. The function of corn flour is to increase sugar content for bacterial fermentation, allowing multi-dimensional complex enzyme bacteria to quickly gain an advantage.

2、 Add the prepared mixture to the mixer for stirring, making sure to mix evenly, thoroughly, and without leaving any lumps.

3、 The mixed ingredients are stacked into long strips with a width of 1.5-2 meters and a height of 0.8-1 meters, and flipped with a flipping machine every 2 days.

4、 Piling takes 2 days to heat up, 4 days to have no odor, 7 days to loosen, 9 days to become fragrant, and 10 days to become fertilizer.

1. On the second day of stacking, the temperature can reach 60 ℃ -80 ℃, killing diseases and pests such as Escherichia coli and insect eggs;

2. On the fourth day, the odor of sheep manure was eliminated; On the 7th day, the compost became loose and dry, covered with white mycelium;

3. On the 9th day, it emits a fragrance of koji;

4. On the 10th day, the bacterial fertilizer will ferment and mature

5、 After slightly drying, it can be crushed by a semi wet material crusher, granulated by an organic fertilizer granulator, dried and dehydrated by a dryer, and then screened by a screening machine. The finished organic fertilizer is ready and can be packaged and stored.

Animal manure organic fertilizer is a new type of organic fertilizer that has been specially treated for partially digested organic matter. It is suitable for geological improvement in alkaline and barren land and has a good effect on increasing crop yield.

What are the characteristics of manure processing organic fertilizer equipment

The green ecological sheep manure produced by the organic fertilizer production line has an organic matter content of over 45%, making it a nutritious and comprehensive organic fertilizer. If different elements are added in a targeted manner, a series of specialized fertilizers for various crops such as vegetables, flowers, fruit trees, grains, cotton, and oil will be formed.

How to choose a suitable organic fertilizer granulator when making organic fertilizer

In the organic fertilizer industry, granulators are a very important equipment. There are also different types of organic fertilizer pelletizers, such as extrusion pelletizers, rotary pelletizers, and disc pelletizers, all of which have their own advantages and disadvantages. The specific one that is good can be based on one’s own needs and production requirements. For a complete set of equipment, the price may vary depending on different brands, specifications, and production capacity. Generally speaking, the price of granulators can range from several thousand to tens of thousands. Of course, the specific price also needs to be determined based on the specifications and functions of the equipment you need.

Different granulation processes for organic fertilizers require different types of granulators. When making organic fertilizers, which suitable granulator should be used? Firstly, we need to understand the advantages and disadvantages of each granulator:

1. Squeezing granulator

Belongs to dry granulation, without the need for drying process, with high granulation density, good fertilizer efficiency, and full organic matter content; It also saves the cost of purchasing dryers and cooling machines, and there is no need to burn coal in the later stage, which saves a significant amount of funds. However, the granulation process of the squeezing granulator belongs to a flat circular shape, which is prone to jamming during machine sowing of crops in the field, and its fluidity is not very good. Therefore, if organic fertilizer is produced for machine sowing farmers, this granulation process should be used with caution, and it is recommended to use compound fertilizer and compound mixed fertilizer.

2. Stock conversion granulator

It is a process that has been used for granulation of compound fertilizers and can also be used to produce organic fertilizers, but the granulation rate is relatively low. If producing organic and inorganic organic fertilizers, this process can be chosen.

3. Disc granulator

It is a relatively traditional process, with smooth grain production and good appearance, but the only drawback is low density; At present, people are pursuing new types and methods of granulation, so the number of users is gradually decreasing (universal type).

4. New Organic Fertilizer Granulator

This process has high yield and smooth processing. If an organic fertilizer throwing machine is added, the granulation can be comparable to disc granulation. However, it is necessary to purchase a dryer and a cooling machine, and the entire set of equipment for this process of organic fertilizer is expensive.

The above are the advantages and disadvantages of mainstream granulation machines on the market. After seeing this, everyone must be able to choose the granulation machine they want! Choosing according to one’s own needs and requirements is appropriate and good!

What should be noted when purchasing organic fertilizer equipment

1. Types of own organic fertilizer production needs

When purchasing organic fertilizer equipment, you should know whether you are making powder fertilizer or granular fertilizer. The main difference between them is that one is organic fertilizer powder and the other is organic fertilizer granules. Generally, the main equipment for the processing technology of granular organic fertilizer equipment is fermentation tank, Mixers, overturning equipment, belt conveying equipment, cylindrical sieves, pulverizers, granulators (double roller granulator, rotary drum granulator, tooth stirring granulator, disc granulator), etc, the production line is also different , including organic fertilizer production line, npk production line and so on. Buy the model of organic fertilizer production line equipment, the annual output is 10,000-50,000 tons, and buy small organic fertilizer production line equipment. The organic fertilizer output of 5 million to 10 million tons is suitable for buying medium and large organic fertilizer production line equipment. The total price of each model is different. Plan the production volume in advance and make a good capital budget to facilitate the later operation turnover.

2. Product conditions of organic fertilizer equipment manufacturers

(1). Quality of organic fertilizer equipment

Are the welding joints uniform and smooth, and are there any corner-cutting behaviors such as missing welding? Is there poor welding or burn-through? The coupling has a compact structure, flexible operation, and easy disassembly and assembly. What is the performance of organic fertilizers? Whether the particle size is uniform. Small problems are the easiest to ignore and often lead to bad consequences!

(2). Safety of organic fertilizer equipment

When purchasing organic fertilizer equipment, safety issues are very important. The organic fertilizer production line must design safety devices. The selection of circuit lines must comply with national standards, and the safety issues in use cannot be underestimated, and professional operating instructions must be provided.

The granulation process flow of organic biological fertilizer production line

The agricultural solid waste resource utilization project adopts a land use model, establishes an organic fertilizer factory, uses livestock and poultry manure such as chickens, pigs, cows, sheep, and crop straw process materials, applies biological fermentation technology, and scientifically processes (biological fermentation, high-temperature sterilization, deodorization, drying) to produce environmentally friendly and efficient organic fertilizers with excellent quality and stable fertilizer efficiency, in order to achieve efficient resource utilization of livestock and poultry waste, and achieve a win-win situation of livestock and poultry breeding benefits and environmental protection ecological benefits.

The granulation process flow of organic biological fertilizer production line

The entire process can be simply divided into three processes: pre-treatment, primary fermentation, and post-treatment.

Pre treatment: After the compost raw materials are transported to the yard, they are weighed by a scale and sent to the mixing and stirring device. Organic wastewater from production and domestic use cannot be mixed in the factory, and must be treated with clean water.

Then add organic biological fermentation compound bacteria (1-2 kg per ton of raw material), and roughly adjust the moisture content of organic fertilizer according to the raw material composition (chicken manure: cassava residue or mushroom residue: straw=6:2:2) to 60% -65%, with a carbon to nitrogen ratio of 20-30. After mixing, proceed to the next process.

When adding ingredients, the brown sugar must be dissolved in water first, and then organic fertilizer fermentation bacteria should be added and stirred thoroughly. Then, the diluent should be evenly sprinkled on the raw materials and thoroughly stirred with a fertilizer mixer.

Attention: The composting raw materials should be treated several hours in advance, soaked in water, and the water used to dilute the biological fermentation bacteria should be considered as drinking water without disinfectants (such as bleach powder).

Primary fermentation: The mixed raw materials are sent to the primary fermentation workshop using a loader to form a fermentation pile. At the same time, the pile is flipped for about 2 days and supplemented with water and nutrients. The fermentation temperature is controlled at 50 ℃ to 65 ℃ (hot to the touch) for aerobic fermentation. The fermentation cycle for this project is 8 days, with one tank of raw materials entering and one tank of semi-finished products exiting each day. After the fermented semi-finished products are discharged, they are ready to enter the next process.

Post processing: Further screen the compost product, and the screened material is processed according to the moisture content. After sieving and granulating, the material is sent to a fertilizer dryer for drying. Various additives are added in proportion, stirred and mixed to produce finished products, which are packaged and stored for sale. The screened material is returned to the crushing process for reuse.

Equipment characteristics and fermentation process of pig manure tank type tipping machine

Functional characteristics of pig manure tank type tipping machine:

The pig manure tank type dumping machine is a dumping equipment that operates on a pre laid track. Therefore, the pig manure tank type tipping machine must be used as a fermentation tank, and the fermentation tank must be laid with tracks.

It is mainly used for the fermentation and flipping of livestock and poultry manure, sludge waste, biogas residue cake, and organic waste. It is mainly used for the composting and fermentation of manure in organic fertilizer production plants, compound fertilizer plants, garbage sludge plants, horticultural fields, and mushroom plantations, as well as various breeding farms.

The difference between pig manure tank type tipping machine and self-propelled tipping machine is that it operates on a track and can flip the materials in the fermentation tank back and forth. Generally, when equipped with a displacement car, it can be used in multiple tanks for aerobic fermentation. It can be used in conjunction with solar fermentation chambers, fermentation tanks, and displacement cars. It has high efficiency, smooth operation, durability, and even flipping and throwing. Implement manual and semi-automatic control functions through the control cabinet.

The pig manure tank type tipping machine is used for flipping and throwing materials in the fermentation tank. Equipped with a displacement vehicle, it can achieve the function of one machine with multiple slots, which can greatly save equipment investment.

In general, the overturning depth should be 1.2 meters, the overturning width should be 6 meters, and the track should be equipped with angle iron below 2 meters and light rail runway above 2 meters.

The pig manure track type turner is suitable for zero emission projects in pig farms. Generally, the pig manure track type turner requires a groove depth of 1.2 meters and a material stacking of 1 meter for flipping and throwing. Standard equipment below 2 meters does not include a shifting car (customizable), and the equipment is equipped with a walking frequency converter and a winding device. There is currently no limit switch, and the equipment needs to be manually operated to move forward and backward. The advantage of pig manure tank stacker over self-propelled tipping machine is that it has a higher processing capacity, but it has requirements for the working environment.
