fertilizer granulator May 20, 2024

Due to the long-term application of chemical fertilizers, the lack of organic fertilizers, and the imbalance of various nutrient ratios, the farmland ecological environment, soil physical and chemical properties and soil microbes are in my country. The bio-organic fertilizer has achieved satisfactory results in the verification of fertilizer efficiency and various crops, and has been recognized by many citizens.

Organic fertilizer granulator equipment double roller granulator uses pressure to agglomerate the solid material, and then squeezes the material through two counter-rotating rollers, which are driven by an eccentric sleeve or a hydraulic system. When extruding solid materials, the air between the powder particles is first removed to rearrange the particles, thereby eliminating the gaps between the materials.

In the npk production line, the extruded organic fertilizer granulator should prevent the granular powder materials from being put into the extrusion granulation equipment, and then the powder materials are compressed by external force. Due to the different modes of external force used, the molecules are reassembled so that the material assumes cylindrical particles. The entire production and extrusion process is mechanized without manual operation. However, agitation granulation primarily uses agitation to form a material into a circle. The bulk product produced by the extruded organic fertilizer granulator has a thickness of 5-20 mm and a surface density of 1.5-3 times that of the feed. The chunks are then sliced, crushed and sieved to obtain the desired granular product.

The double-roll extrusion granulator adopts the non-drying and normal temperature process, and the particle strength is high. In the npk fertilizer production line, the increase in the accumulation proportion is more obvious than other granulation methods, the reliability of electric power small operation, the three kinds of wastes are not discharged, and the operation is stable , easy maintenance, reasonable process layout, advanced technology and low production cost. The twin-roll extrusion granulator realizes the green reuse of resources and has huge market potential.

The granulation process of an annual production line of 20000 tons of chicken manure organic fertilizer:

The granular organic fertilizer production line with an annual output of 20000 tons of chicken manure includes a stacker – vertical crusher – drum screening machine (optional here) – batching machine and horizontal mixer (optional equipment) – disc granulator – dryer and cooling machine – drum screening machine – round throwing machine (optional) – coating machine (optional) – single bucket packaging machine.

With an annual output of 20000 tons and a large scale, it is possible to consider using a granular fertilizer production line. The granular fertilizer production line includes two important processes, fermentation and granulation.

Fermentation process for the production of chicken manure organic fertilizer:

Mix chicken manure, straw, mushroom residue, and other materials together, add fermentation agents, and under the action of the fermentation agents, the material pile will generally heat up in about 2 days. At this time, flipping equipment can be used to flip the pile to increase the oxygen content and moisture content of the material pile. If local environmental protection is strict, horizontal fermentation tanks can be used for fermentation. The fermentation process in horizontal fermentation tanks is fully sealed and contains deodorization devices, which will not cause environmental pollution.

Granulation process of chicken manure organic fertilizer production line:

After sufficient fermentation and maturation, the material enters the granulation process. The finer the material, the better the shape of the produced particles. Therefore, it is necessary to first use a vertical crusher for crushing, and then use a drum screening machine to screen. Materials with unqualified dimensions enter the crushing process again, and qualified materials enter the organic fertilizer granulator. An annual output of 20000 tons of granular fertilizer. It is recommended to use disc granulators, toothed granulators, etc. for circular particles, and flat mold granulators and roller extrusion granulators are recommended for cylindrical particles. After the granulation is completed, the screening machine is used again for screening. Unqualified particle materials enter the crushing granulation process again, and qualified particles enter the packaging machine.

The production process of fermentation and granulation is relatively simple, but equipment selection is important. Stable performance and well-designed equipment can not only avoid production accidents, but also improve the quality of organic fertilizers.

Maintenance methods for the entire set of equipment in organic fertilizer production lines

At the same time, we must pay attention to the safety accidents that may occur when the equipment is continuously operated under high pressure and low temperature. Various problems that may occur in organic fertilizer processing equipment. When there is organic fertilizer equipment production, we must pay attention to safety. We can only work better when we have security. At the same time, pay attention to the daily maintenance of the equipment.

1. Keep the machine clean. After use, the stains and debris outside the organic fertilizer granulator should be removed, coated with black oil, waste oil, etc, and covered with a protective cover.

2. Deal with corroded and damaged parts in time. When the equipment is not working, the corroded or damaged parts in the equipment should be removed, especially the motor, reducer, conveyor belt, transmission chain, etc.

3. Pay attention to the operation of the organic fertilizer equipment. Once serious abnormal noise is found, the npk fertilizer production line inspection should be stopped immediately and used after troubleshooting.

4. For outdoor organic fertilizer equipment, the deformed part should be leveled or erected to remove the factors causing deformation.

5. When the organic fertilizer equipment is overhauled, the working gap should be re-measured each time and adjusted several times. It can only be used if the standard is met.

6. Do a good job of thermal insulation. The drive part of the fertilizer equipment may start slowly or fail to start due to freezing. Therefore, insulation measures can be taken. At the same time, antifreeze is also used for raw materials commonly used in the operation of organic fertilizer equipment.

How to choose a suitable pig manure organic fertilizer crusher?

fertilizer granulator May 20, 2024

There are many types of organic fertilizer crushers, including vertical crushers, chain crushers, semi wet material crushers, urea crushers, straw crushers, new straw crushers, etc. The selection of a suitable pig manure organic fertilizer crusher mainly depends on several aspects such as production scale, material requirements, and operational requirements. Now let me give you a detailed introduction.

Firstly, according to the scale of production, pig manure organic fertilizer crushers can be mainly divided into three types: small, medium, and large. The small pig manure organic fertilizer crusher is suitable for small family farms or individual operators, with a general processing capacity of 1-2 tons/hour; The medium-sized pig manure organic fertilizer crusher is suitable for medium-sized factories or farms, with a processing capacity of 2-5 tons/hour; Large scale pig manure organic fertilizer crusher is suitable for large factories or farms, with a processing capacity of over 5 tons/hour.

Secondly, according to material requirements, the pig manure organic fertilizer crusher can be divided into two types: stainless steel and carbon steel. The stainless steel pig manure organic fertilizer crusher has corrosion resistance and is suitable for processing pig manure containing more acidic and alkaline components, while the carbon steel pig manure organic fertilizer crusher is more wear-resistant and suitable for processing pig manure with strong viscosity.

Finally, according to operational requirements, the pig manure organic fertilizer crusher can be divided into two types: manual and automatic. The manual pig manure organic fertilizer crusher requires manual operation and is suitable for places with simple operation and sufficient human resources; The automatic pig manure organic fertilizer crusher has automatic control function, suitable for situations with high work intensity and complex operation.

In summary, selecting the right pig manure organic fertilizer crusher requires comprehensive consideration of production scale, material requirements, and operational requirements.

Factors affecting the granulation speed of organic fertilizer rotary drum granulator

fertilizer granulator May 20, 2024

The principle of rotary drum granulator is that the material relies on the surface tension, the right amount of liquid phase, the extrusion force generated by the rolling between the materials, and the material takes small particles as the core in the correct direction of movement in the granulator, and sucks big during the rolling. Small attached, glued into a ball. The higher the rolling frequency in a certain period of time, the higher the spheroidization rate, and the more rounded the pellets are after they are formed.

1. In the npk production line, we have encountered two situations due to the different friction between the material and the wall of the granulator. The inner surface of the granulator has a large surface finish, which reduces the friction between the material and the cylinder wall, and weakens the upward movement of the material. If the material does not roll, particles cannot be produced. In response to this situation, we can solve it by adjusting the speed of the granulator and installing a small copy board inside.

2. The material in the rotary drum granulator is seriously sticking to the wall, and the friction between the material in the granulator and the cylinder wall is enhanced, and the material in the granulator is lifted too high, causing the material to be thrown down from the top, so that the formed particles are not round. And too many large particles, we think there are two reasons for this situation: on the one hand, it is caused by too many viscous materials. The inside of the machine is not smooth, which is solved by changing the internal material and increasing the smoothness of the granulator.

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

fertilizer granulator May 20, 2024

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.

fertilizer granulator May 20, 2024

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

fertilizer granulator May 15, 2024

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

fertilizer granulator May 15, 2024

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.
