Production process and equipment characteristics of drum screening machines

fertilizer granulator Jul 20, 2023

The production process of Organic fertilizer is mainly to mix the organic solid waste with water content less than 60% with auxiliary materials (plant straw, etc.), microbial fermentation agents, etc., and make it fully decomposed, sterilized, deodorized and dewatered through pool type aerobic continuous fermentation. The moisture content of the decomposed material is generally 30-35%. After screening and magnetic separation, it can be directly used to produce spherical Manure or powder Manure after further drying. Process introduction: pour the raw materials into the Organic fertilizer mixer for mixing, mix them evenly and then crush them, and then input them into the Organic fertilizer granulator with a belt conveyor; After granulation and forming, it is sent to the dryer for drying, and then sent to the cooler for cooling through the elevator or belt conveyor. The water content reaches below 6%. After cooling, it is screened. Large particles are crushed into fine materials through the return Organic fertilizer grinder, and the fine materials enter the disk granulator. The coarse returned materials enter the granulator after crushing, and the finished products are directly packaged.

The drum screen is a common equipment in the production of Organic fertilizer and compound fertilizer. It is mainly used for the separation of finished products and returned materials, and can also realize the classification of finished products, so that finished products can be classified evenly. Adopting a combination screen, it is easy to maintain and replace. The machine has a simple structure, convenient operation, and stable operation.

What are the characteristics of drum screening machines?

The drum screening machine is a relay operated vibrating screen, which is a new generation of self-cleaning screening equipment after the ordinary mesh drum screening produced by major domestic companies. It is widely used for screening various solid materials with particle sizes less than 300mm. It has many characteristics such as high screening efficiency, low noise, small dust emission, long service life, small maintenance volume, and convenient maintenance. Its screening capacity is 60 tons/hour to 1000 tons/hour. The comprehensive utilization of electricity (mainly circulating fluidized bed boilers), which mainly burns low-quality coal, has rapidly emerged in China. Fuels mainly composed of coal gangue and coal slurry often have characteristics such as stickiness, wetness, dirt, and impurities. The coal conveying system generally suffers from clogging of the screening machine, low screening efficiency, high crusher wear, and high energy consumption.

What environmental protection methods do Organic fertilizer equipment manufacturers have?

fertilizer granulator Jul 20, 2023

Organic fertilizer production is an effective means of waste resource utilization, which can reduce the pollution of waste to the environment and is an environmental protection project. However, the management of some fertilizer production process manufacturers is not standardized. Many manufacturers produce in the open or build simple sheds, which will inevitably cause secondary pollution to the environment in the fertilizer production process, which violates the principle of environmental protection. Today, let’s talk about the pollution sources of organic fertilizer manufacturers and the corresponding treatment methods?
1. Waste gas and odor pollution
Most of the raw materials of organic fertilizer are wastes and perishable substances, which are easy to produce ammonia, hydrogen sulfide and other harmful gases during the storage and fermentation of organic fertilizer raw materials.
At present, there are many ways to eliminate odor and exhaust gas, such as water washing, combustion, adsorption, air dilution, masking, ozonation, plasma and biological deodorization. Biological deodorization is the most widely used method in the production of organic fertilizer manufacturers. This method uses the activities of microorganisms to decompose and transform the odor to achieve the purpose of deodorization. This method is simple and easy to operate. It is suggested that the organic fertilizer manufacturers should build closed raw material warehouse, fermentation workshop and secondary aging workshop when conditions permit, so as to reduce the leakage of odor and harmful gas in the transformation process.

2. Waste liquid pollution
Many raw materials of organic fertilizer contain a lot of water, such as pig manure, cow manure, chicken manure and other raw materials. In the process of raw material accumulation and fermentation, there will be waste liquid flowing out and infiltrating into the ground to pollute the underground water, so it is necessary to cement harden and impervious the ground of the fermentation workshop of the raw material warehouse during the construction of the plant.
3. Dust pollution
Dust pollution is the main pollution in the fertilizer production process, which needs to be treated carefully. There are many links of dust pollution.
(1) When the raw materials are unloaded into the warehouse and handled in different workshops with the carrier
(2) When the fermentation compost windrow turner dumps the raw materials
(3) When using the crusher to crush raw materials
(4) When the fertilizer particles are dried and cooled
Many organic fertilizer manufacturers will build dedusting rooms in their workshops, and use induced draft fans and dust collectors to solve dust problems. Common dedusting equipment include: cyclone deduster, pulse deduster, water curtain deduster, bag deduster, etc. It is explained here that although dust is the source of pollution, these dust are all from the raw materials of organic fertilizer. After collection, they can be added to the raw materials for fermentation and then continue to produce organic fertilizer.
4. Noise pollution
In addition to choosing the plant site far away from the residential area, low-noise organic fertilizer machine should be selected as far as possible; equipment maintenance should be strengthened to avoid high noise caused by abnormal operation of equipment; installation of equipment can increase damping measures; reasonable planning of plant site, use of buildings to reduce noise; construction of green belts, use of vegetation to absorb sound and other measures to reduce noise.  

Startup guideline of Huaqiang excellent-quality disc granulator

fertilizer granulator Jul 20, 2023

1. The control of the water content of the disc granulator in the operation of the fertilizer production line. The granulation process of the disc granulator requires high moisture content, and poor moisture control will cause the granulation speed to decrease. Therefore, during the processing, attention should be paid to the sprayer to observe the control changes of the moisture of the granulated raw materials.

2. The personnel operating the disc granulator should pay attention to the quality of various materials during the feeding control process to ensure that sundries, large lumps and large particles are not mixed into the feed. In addition, they should also pay attention to the temperature of the equipment feed, because if the temperature of the die is too high, the material will easily break and stick to the die after startup. In this case, they should take care to wait for the cooling before continuing.

3. Pay attention to the change of the inclination angle of the disc granulator during operation. The disc granulator has a certain angle of inclination. If the inclination angle changes due to accidental reasons, it will also affect the granulation rate of the organic fertilizer particles and also affect the service life.

4. During the operation of the disc granulator, the operator should also pay attention to the temperature change of the body at any time. Unlike the NPK fertilizer granulator, the production process of the disc granulator is very intuitive. The operator can touch the blade with clean hands. If the blade does not touch the hand, the temperature should rise immediately until the blade touches the hand. Then, during the normal operation of the granulator, the operator should maintain a stable machine temperature and do not let the temperature rise and fall. In addition, the operator should pay attention to maintaining the temperature around the vent until the head temperature reaches about 200 degrees Celsius.

5. When using the disc granulator, in order to ensure that the particles are uniform, smooth and complete, attention should be paid to ensure that the fertilizer production line feed evenly and fully. The feeding speed and discharging speed of fertilizer production line should be properly matched to avoid the decrease of granule quality and yield.

6. When the disc granulator body is unstable, check whether the coupling clearance is too tight and loosen it in time. If the bearing part of the reducer is heated or noisy, it should be repaired and refuelled in time.

7. During the installation of the disc granulator, the main body should be kept perpendicular to the horizontal plane, and the verticality should be calibrated and corrected after installation.

8. Before the installation of the disc granulator, the concrete foundation shall be prepared, installed on the horizontal concrete foundation and fixed with bolts.

9. Before power on, make sure that the power on meets the power supply requirements set by the disc granulator, and configure the power line and control switch according to the equipment power supply.

10. After installation, check whether the bolts of each part are loose and whether the door of the main engine compartment is fastened.

fertilizer granulator Jul 20, 2023

When installing the new two-in-one agitator granulator, pay attention to:
1. Selection of installation location
The new two-in-one agitator granulator should be installed on a horizontal concrete foundation. For safety reasons, the organic fertilizer granulator should be further reinforced with anchor bolts. During installation, the main body of the new agitator two-in-one granulator should be kept perpendicular to the horizontal plane. After installation, further inspection should be carried out, including whether the bolts in all parts are fixed, The situation should be reinforced in time to ensure that all parts are installed.

2. Preparation before operation
When the power supply of the new type agitator two in one granulator is configured, it should be selected according to the power of the organic fertilizer granulator itself. After checking and confirming that there is no problem, carry out no-load test run. The test run is normal and can be put into production.
3. Use and maintenance of organic fertilizer granulator
In the maintenance of the new type of two in one granulator, pay attention to the selection of lubricants, because good lubricants have a great impact on the life of bearings, and the use of poor lubricants is prohibited. Generally, the parts requiring sealing and oiling include rotating bearing, roller bearing, all gears, movable bearing and sliding plane. Regular and regular inspection shall be carried out. Once problems are found, maintenance shall be carried out in time. If there is abnormal sound during use, production shall be stopped immediately to avoid safety accidents.

The new organic fertilizer granulator has a wide range of applications, especially for the granulation of light and fine powder. The finer the basic particles of fine powder materials, the higher the degree of sphericity of the particles, and the better the quality of the particles. Generally, the particle size of the material before granulation must be less than 200 mesh. Typical application materials include chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc. Due to the particularity of the granulation of municipal solid wastes such as livestock manure, organic fertilizer, degummed fertilizer, green manure, sea manure, cake fertilizer, peat, soil miscellaneous fertilizer, three wastes and microorganisms, the particles are irregular.

The working principle and equipment advantages of the roller extrusion granulator

fertilizer granulator Jul 20, 2023

At present, there are many kinds of Manure products on the market, and their production processes are also diverse. Different production processes have their own advantages and disadvantages. Among them, the extrusion granulation process is simple, easy to operate, zero discharge of “three wastes”, high automation, large output, and the product is not easy to agglomerate. It stands out from many processes and is increasingly favored by enterprises.

The granulation characteristics of the roller extrusion granulator: Extrusion granulation is a dry granulation process in which solid materials rely on external pressure to agglomerate. The material particles are close together under high pressure, and the generated molecular force, electrostatic force, and other forces cause the particles to tightly bond together. Common extrusion granulation methods include roller extrusion granulation, spiral extrusion granulation, and disc die extrusion granulation.

The process of roller extrusion granulation machine: The roller extrusion granulation process adopts German roller compression granulation equipment, which uses the strong pressure generated by the roller press to instantly extrude the powder material into shape, and then obtains qualified products through crushing, screening and other processes.

The working principle of the roller extrusion granulator: After materials with different physical properties are reasonably matched and metered and mixed, they are transported by a bucket elevator, adjusted for humidity, and distributed by an automatic feeder into a pair of reverse rotating roller presses. Under the extrusion of the rollers, they form regularly shaped pieces of material, which are then crushed, screened, polished, and anti caking processes to achieve uniform particle size and hardness standards Compound fertilizer products with full particles.

The roller extrusion granulator is a key equipment for compound fertilizer granulation, with advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, and matching with corresponding equipment to form a small production line, which can form a certain capacity of continuous and mechanized production. Adopting the eugenic formula, without drying, produced at room temperature, the product is rolled and formed in one go, ensuring that the product quality meets the technical requirements of compound fertilizers. It is an updated product for the production of high, medium, and low concentration specialized compound fertilizers for various crops and the energy-saving and consumption reduction of the compound fertilizer industry.

Equipment principle and performance advantages of self-propelled composting machines

fertilizer granulator Jul 20, 2023

The self-propelled composter is a Manure fermentation equipment developed based on dynamic composting. The earliest composting process is static composting, which is often converted into anaerobic fermentation due to insufficient oxygen supply, which will produce a large amount of hydrogen sulfide and other odor, and there is an explosion risk. Later, our company developed a new generation of Manure fermentation equipment, self-propelled fermentation composter, which can make full use of space, and the whole machine is solid; The vehicle body is flexible and can easily and conveniently lift the drum as a whole; Adopting advanced engineering machinery transmission technology to ensure no loss between energy conversions; Each component is connected to each other and can be adjusted separately; Under normal operation and attention to maintenance, using the machine is zero fault; Fully ferment the raw materials to quickly achieve the effect of no odor, no harmful bacteria such as Escherichia coli.

The self-propelled composting machine/self-propelled tipping machine has obvious advantages such as low investment, low energy consumption, fast composting, and high yield. The self-propelled Manure composter is an ideal equipment to use modern technology to transform agricultural wastes, stored feces and organic household garbage into high-quality biological Manure. Main features: It saves a lot of civil engineering and manpower and material engineering, making the scalability of fertilizer production more arbitrary and not limited by the site, allowing for multiple uses of one machine.

The self-propelled composter is the main machine of the complete set of equipment dedicated to the production of Manure. It adopts a four-wheel walking design, and can move forward, backward, and turn. It is operated by one person. When driving, the whole vehicle rides on the pre stacked strip Manure pile, and the rotating knife hung under the machine is used to remix, fluff, and move the raw materials of the fertilizer machine. After the vehicle passes, a new strip stack is formed, which can be operated either in the open field or in the workshop shed. A major technological breakthrough of this machine lies in the integration of the crushing function in the later stage of material fermentation. As the material gradually dehydrates, the knife equipped with a crushing device can effectively crush the plates formed during the fermentation process of the fertilizer. Not only does it save a crusher, but it also greatly improves the efficiency of crushing, reduces costs, and fundamentally solves the problem of limited production capacity of the crusher. Composting machines have significant effects compared to other types such as “tipping machines”, “mixers”, and “spiral stirring machines”. So one machine can be used for many purposes. It is not only a Manure dumper, but also a Manure grinder.

The Seven Steps of Processing Fertilizer on the Cow Manure Fertilizer Production Line

The cattle manure fertilizer production process, only 7 steps, makes the manure become organic fertilizer, and makes the cow manure greatly profitable.

1. Fermentation stage of cattle manure fertilizer production process:
Collect cow dung and urine, add auxiliary materials to make compost, and let it ferment. In the fermentation of seed, we use a dumper to fully ferment the cow dung, which can only be done in a timely and even way.
2. The composted materials, such as N, P, K and other inorganic fertilizers, and other additives are crushed, proportioned and mixed through the material crusher and horizontal mixer according to the proportion.
3. Granulation stage of cattle manure fertilizer production process:
A new type of organic fertilizer granulator is used to granulate materials.
4. Screening and recycling system of cattle manure fertilizer production process:
The size of the particles output from the pelletizing and forming system is different, so it needs to be screened and graded. The selected rotary screen machine requires small vibration, low noise, convenient screen changing and equipped with screen surface cleaning device.
5. Drying stage of cattle manure fertilizer production process:
Using the organic fertilizer dryer, the sieved particles can be further removed from the water to meet the standard requirements of the moisture content of organic fertilizer.
6. Cooling stage of cattle manure fertilizer production process:
Cooling the granular materials with a cooler is helpful for the storage and quality of the granules.
7. Packaging stage of cattle manure fertilizer production process:
The cooled granular materials are transported into the finished product warehouse by the bucket elevator. The granular materials can be weighed and packed quantitatively by automatic packing scale.
In the whole production process, the fermentation equipment of organic fertilizer is very important, and the quality of organic fertilizer also depends on the fermentation process. Therefore, the fermentation process of organic fertilizer is paid attention to by everyone. In the process of organic fertilizer fermentation, the heating time of organic fertilizer equipment refers to the early stage of the composting process. The temperature rise of compost gradually increased from room temperature to 45 ℃. The main microorganisms are thermophilic microorganisms, including bacteria, fungi and actinomycetes. The differentiation matrix was mainly carbohydrate and starch. The fruiting bodies of fungi can be found in time, and animals and protozoa participate in differentiation.
