Production process of granulator summarized by organic fertilizer production line

The organic fertilizer manufacturing process is mainly to screen and magnetically sort the organic waste with a water content of about 30% to 35% after fermentation and decay to prepare round granular organic fertilizer, and add functional bacteria to produce biological organic Fertilizer, adding nitrogen, phosphorus and potassium (total nutrient content less than 15%) can produce organic and inorganic fertilizers.

After the fermented organic waste is subjected to magnetic separation and sieving, the raw materials with binder and other ingredients to be compatible are metered according to the ratio requirements, and then lifted into a multi-dimensional high-efficiency mixer by a bucket elevator for rapid mixing. The mixed material slips out into the mixing bin, and is continuously and uniformly fed into the extrusion granulator by the disc feeder to make cylindrical particles; the cylindrical particles are polished and formed into spherical particles by the circular particle polishing and shaping machine, and are formed by the belt. The machine is fed into the drying, cooling and screening machine (three-in-one model). The particles are dried at a low temperature and large air volume (≤65 ℃) in the front section of the drying and cooling screening machine, and then enter the cooling section for air cooling. After sufficient cooling The material enters the screen installed at the end of the cylinder, and the sieved finished particles are transported by the elevator to the finished product silo, which is measured and packaged by the packaging system; the sifted large particles are returned to the mixing granulation system after crushing; The sieved small particles (basically without powder) can be made into small packages and sold directly.

Equipment composition and application scope of drum granulator

The working principle of the drum granulator is that the belt and pulley are driven by the main motor and transmitted to the driving shaft through the reducer. The split gear installed on the driving shaft is engaged with the large gear ring fixed on the body and works in opposite direction. The material is added from the feed end and passed through the cylinder. It is made into particles by the special structure inside the cylinder, and then flows out through the outlet. Because of the continuous entry of materials and the continuous rotation of the granulator, mass production can be realized.

Overview of drum granulator structure The whole machine can be divided into five parts:

Bracket part: the whole rotating part of the machine body is supported by the bracket, which bears a large force. Therefore, the bracket part of the machine is made of medium carbon steel plate and channel steel dryly, and has passed strict quality control and special process requirements, which has reached the purpose of the machine. In addition, it is more important to fix the supporting roller on the rack. Considering that it will cause great friction with the body rolling belt, our factory specially selects anti-corrosion and wear-resistant materials, which greatly improves the service life of the machine. The supporting roller frame also adopts the casting integration technology. In addition, there are lifting hooks at the four corners of the supporting roller frame, which is convenient for loading, unloading and transportation

Drive part: the drive part of the whole granulator is the most important part. The whole body works in this way. The drive frame is made of high-quality channel steel dryly connected, and has passed the strict quality requirements. The main motor and reducer installed on the drive frame are ISO performance reliable products, and the quality is reliable. The motor drives the pulley, triangular belt, and reducer to the main shaft, so that the body works, The transmission reducer is driven by nylon shaft pin coupling in the main shaft working part.

Big gear: fixed on the machine body, it fits with the transmission pinion and drives the machine body to work in the opposite direction. It uses high-tech wear-resistant materials, so that the service life of the machine is longer.

Rolling belt: fixed to both sides of the body to support the whole body.

Body part: The body part of the whole granulator is particularly important. It is made of high-quality and medium-carbon steel plate dryly connected, with special rubber lining plate or acid-resistant stainless steel lining plate built in, to achieve automatic scar removal and tumor removal, eliminating the traditional scraper device, and achieving the purpose of this machine through strict quality control and special process requirements.

The drum granulator is especially suitable for granulation of light fine powder materials, especially for granulation of organic compound fertilizers. The finer the basic particles of the fine powder material, the higher the sphericity of the particles, and the better the balling quality. It is generally required that the particle size of materials before granulation should be less than 50 mesh. Typical application materials: chicken manure, pig manure, cow manure, carbon black, clay, kaolin, carbon, phosphorus and potassium and other organic compound fertilizers are suitable. The granulator developed and produced by our company is based on the manufacturing principle and technology of the stirrer granulator and the drum granulator. It is carefully developed and repeatedly tested. The granulator can produce bacteria at normal temperature, with reasonable structure design, and can produce spherical granular products. The granulator has the characteristics of low water content, easy drying, high molding rate, good particle strength, and beautiful appearance. It is the ideal bio-organic fertilizer and organic-inorganic fertilizer today, Granulation equipment for organic and inorganic compound fertilizers.

Characteristics and application scope of different types of organic fertilizer granulators

Organic fertilizer granulator machine can effectively solve the environmental pollution caused by the excrement discharge of the aquaculture industry, thereby reducing the eutrophication caused by surface and groundwater pollution caused by organic waste, which is conducive to improving the safety and quality of agricultural products, and for the comprehensive cultivation of edible green vegetable melons If a good foundation is laid, the ecological and environmental benefits are extremely significant.

The characteristics of the organic fertilizer granulator are:
1. The granules produced are spherical.
2. The organic matter content can be as high as 100%, to achieve pure organic matter granulation.
3. The organic particles can be inlaid with each other under a certain force, and there is no need to add a binder during granulation.
4. The granules are solid and can be sieved after granulation to reduce drying energy consumption.
5. The organic matter after fermentation does not need to be dried, and the moisture content of the raw material can be 20-40%.

The scope of application of organic fertilizer granulator is also very wide. The finer the basic particles of organic materials, the higher the sphericity of the particles and the better the quality of the balls. It is generally required that the particle size of the material before granulation should be less than 200 mesh. Typical application materials: chicken manure, pig manure, cow dung, charcoal, clay, kaolin, etc. It is specially used for granulation of organic fermented fertilizers for municipal solid waste, such as organic manure, animal manure, manure, manure, composted manure, green manure, sea manure, cake manure, peat, soil and other fertilizers, three wastes, microorganisms The particles are irregular spheres. The qualified granulation rate of the granulator is over 90%, which is suitable for many different formulas. The granulator is best for direct granulation after fermentation of organic fertilizer.

Precautions during fermentation of organic fertilizer production line

Matters needing attention during the fermentation of organic fertilizer manufacturing process:

1. Requirements for fermentation raw materials

Fermentation raw materials (such as agricultural wastes such as feces) are preferably fresh without natural recycling.

2. Accessories requirements

Fermentation auxiliary materials (such as straw, rice bran, etc.) should have a moderate water content, strong water absorption, suitable particles or length, and should not be too large. The amount of addition should be determined according to the moisture content of the fermentation raw material.

3. The strains should be removed

Organic fertilizer fermentation strains require at least 50 grams (1 or 2) for one ton of raw materials. Considering that it cannot be evenly spread on the fermentation materials, when using it, first mix 50 grams of strains with 500 grams (1 kg) Stir any kind of raw materials such as wheat drum, sawdust, oil dry, rice bran, etc., and then sprinkle it into the fermentation material, and then stir and pile up the fermentation evenly.

4. The fermentation moisture is adjusted well

The moisture adjustment of raw and auxiliary materials is the most important, which is related to the success or failure of fermentation. Moisture requirements are: after the original accessories are mixed, hold them in a ball and fall on the ground into two pieces. The proportion of general auxiliary materials (such as straw, rice straw, etc.) is 10% to 30% (weight percentage with raw materials). If calculated according to the volume ratio of the two, it is generally 2 parts of raw materials and 1 part of auxiliary materials.

5. The length, width and height of the fermentation stack should meet the standard

It is required that the width of the fermentation product is not less than 1.5 meters, the height is not less than 1 meter, and the length is not limited.

Input of a complete set of granular organic fertilizer production line equipment and supporting facilities

1. Centralized treatment scheme of livestock and poultry excrement: build a relatively large excrement treatment station in the centralized breeding area of scale (one machine with multiple tanks). For daily treatment of livestock and poultry excrement of more than 12 tons, use a 3M span trough tipper; Build a 300-500 square meter transparent greenhouse, with several fermentation tanks built in the greenhouse (the cost depends on the local actual situation due to different materials).

2. Dispersed treatment scheme of livestock and poultry excrement: 2M span fermentation equipment is built in two farms, and the single unit price is about 200-300 square meters of glass fiber reinforced plastic shed (the cost depends on the local actual situation due to different materials)

So how to use livestock manure and crop straw to ferment organic fertilizer:

1、 Material ratio. Mix chicken manure, pig manure, mushroom residue, straw, dry soil powder, etc. in proper proportion. About 3-4 tons of fresh manure are added with 1 kg of organic fertilizer starter. The starter is diluted and evenly scattered into the manure pile, and mixed evenly.

2、 Material stacking. When making a pile, making it too small will affect the fermentation. The height of the pile is 1.5 meters to 2 meters, the width is 2 meters to 3 meters, and the length is more than 3 meters, so the fermentation effect is better.

3、 Moisture requirements. The moisture content of fermentation materials should be controlled at about 65%. Too high or too low is not conducive to fermentation, and fermentation is slow with little water; Too much water, poor ventilation, slow temperature rise and odor. If the water content is too high, straw, mushroom residue, dry soil powder, etc. can be added. If the water content is appropriate, you can grasp a handful of materials tightly, see the watermark on the finger joint, but do not drip, and disperse immediately after landing.

4、 Turn over the pile for ventilation. During the fermentation process, oxygen should be properly supplied and the pile should be turned over (several times when the temperature rises to 75 ℃ or above). The temperature of the pile should be controlled at about 65 ℃. Too high temperature has an impact on nutrients. Fifth, fermentation is completed. Generally, the fermentation can be completed in 5 to 7 days. The material is dark brown and the temperature drops to normal temperature, indicating that the fermentation is completed.

The complete set of granular organic fertilizer production line equipment includes: trough fermentation equipment – forklift silo – pulverizer – mixing mixer – disc granulator – dryer – cooler – screening machine – coating machine – packaging machine, and the equipment is connected by conveyor.

What is the role of fermented organic fertilizer (chicken manure for example):

1. Produce a variety of enzymes to control continuous cropping and root-knot nematodes.

2. It contains beneficial microbial flora, which can activate nitrogen in the air, release potassium nutrients and supplement soil organic matter.

3. The soil is soft and easy to cultivate, promoting the soil aggregate structure, releasing soil pores and promoting the growth of root groups. Keep the soil water and fertilizer.

What should npk fertilizer granulator pay attention to when processing fertilizer?

Each granulator has its functions and its differences, and the disc fertilizer granulator machine also has its grading effect. The disc granulator makes the powdery material change from small to large from the bottom of the disc, and then form granules , Spilled into the outer disk. Then the diameter of its outer disc becomes larger, and the linear velocity of the particles increases rapidly. The particles are rolled while rolling to form spherical particles. Finally, the larger particles are sent to the dryer by a belt conveyor for drying.

In actual production, the disc granulator must determine the tilt angle and speed according to various raw materials. To operate. The material required for the granulation of the disc granulator is very important for its cohesiveness and plasticity. The balls with different particle sizes will leave the edge of the disc and roll down according to the different separation angles due to the different gravity In the process of continuous rolling, the ball will continuously evacuate the water in the ball out of the surface, so that the ball has a certain hardness, and then follow the edge of the plate to discharge out of the plate. If there are uneven particles, the granulator will return again to continue granulation. The granules produced are of uniform size.
