https://www.fertilizerproductionprocess.com/production-line/fertilizer-disc-granulation-production-line-process.html
1. The recovered chicken manure, sheep manure and cattle manure are directly sent to the fermentation area.
2. Poultry manure is piled after primary fermentation and secondary aging to eliminate the odor of livestock manure. Fermentation bacteria can be added at this stage to decompose the crude fiber so that the particle size after pulverization meets the particle size requirements of granulation production.
3. Crush the fermented materials that have completed the secondary aging and stacking process and enter the mixing and stirring system. Before mixing and stirring, according to the formula, add N, P, K and some other trace elements into the mixing and stirring system and start mixing.
4. Transport the mixed materials into granulation equipment, and use fertilizer disc granulator to make granules. https://www.fertilizerproductionprocess.com/fertilizer-granulator-machine-series/disc-granulator.html
5. After the wet particles are dried by the drum dryer to remove moisture, they enter the cooling system
6. After the material is lowered to room temperature, the screening starts, and the product particles that meet the requirements enter the coating machine, and the packaging starts after the coating film is wrapped. The granules that do not meet the requirements are crushed by the pulverizer and returned to the granulation system, and then continue to be granulated after being processed by the pulverizer.
7. Automatic weighing and packaging of finished products.
Therefore, the entire fertilizer production process (https://www.fertilizerproductionprocess.com/production-line/) is mainly to compost and ferment poultry manure, and then use the decomposed compost for granulation. First of all, the raw materials of organic fertilizer can be chicken manure, cow manure, pig manure, etc. The equipment for producing organic fertilizer is basically the same. Now the common equipment in the fertilizer industry are: compost fermentation equipment, batching equipment, mixing equipment, crushing equipment, granulating equipment, drying and cooling equipment, screening equipment, coating equipment, packaging equipment.
Disc fertilizer manufacturing process
https://www.fertilizerproductionprocess.com/production-line/fertilizer-disc-granulation-production-line-process.html
The disc granulator is composed of an angled tray and a supporting structure. There are many types of disc granulator, with diameters of 0.8m, 1m, 1.5m, 1.8m, 2m, 2.8m, 3m, etc.
The inclination angle and the rotating speed of the disc are adjustable. The material mixed by the mixer is sent to the top of the disc by the belt conveyor, and continuously enters into the disc quantitatively. The material in the disc is bonded by a spray of adhesive and wrapped into granules. As the disc rolls, the particles grow up gradually.
Due to the remarkable grading capacity of the disc granulation machine, large particles float on top and are continuously discharged from the bottom of the disc. The smaller particles remain in the plate and stick with the newly added material and continue to grow.
Advantages of fertilizer disc granulator

The disc granulator granulates very uniformly, returns very little material, and has a large production capacity. An ordinary disc pelletizer can produce 1-3 tons of finished fertilizer per hour. In the fertilizer production process, the disc granulating machine is currently the most used granulation equipment. It has the advantages of simple structure, low cost and convenient maintenance. https://www.fertilizerproductionprocess.com/production-line/
How to use disc granulation machine
1. Check whether the reducer is filled with gear oil and whether the direction of rotation of the disc is correct before starting and starting.
2. After running and pressing the start button, the host starts, and observe whether the equipment is operating normally, whether there is vibration, and whether the rotation is stable.
3. After the filler and equipment are running normally, you can add materials and water.
4. After granulation adjustment and filling, the angle of the disc can be adjusted according to requirements to make the granules reach the required size.

Characteristics of pig manure organic fertilizer production line
1. Pig manure bio organic fertilizer does not contain any chemical components. Due to the poor digestion ability of pigs, only 25% of the nutrients can be consumed, while the other 75% of the nutrients in the feed are discharged with the feces, so that the dry products contain nitrogen, phosphorus, potassium, organic matter, amino acids, protein and other components
2. Organic matter is the main substance in pig manure organic fertilizer, which increases the content of organic matter in soil. Organic matter can improve the physical, chemical and biological characteristics of soil, ripen the soil and improve soil fertility.
3. Pig manure bio organic fertilizer not only increases a lot of organic colloids, but also decomposes and transforms many organic matters into organic colloids with the help of microorganisms, which greatly increases the adsorption surface of soil, and produces a lot of sticky substances, which makes the soil particles cemented into stable granular structure, improves the soil water, fertilizer and air permeability performance, and the ability to adjust soil temperature
4. Pig manure bio-organic fertilizer can multiply microorganisms in the soil, especially many beneficial microorganisms, such as nitrogen-fixing bacteria, ammonifying bacteria, cellulose decomposing bacteria, nitrifying bacteria, etc. There are animal digestive tract secretions in pig manure organic fertilizer All kinds of active enzymes, as well as various enzymes produced by microorganisms, after these substances are applied to the soil, the soil enzyme activity can be greatly improved.
1. Decomposition method:
Collect cow dung and cow urine, mix with hay and rotten silage to make compost, and let it ferment. In the fermentation process, the compost turner machine is used to fully ferment the cow dung. This can only be achieved by turning the dump in time and evenly. Now some places are very dry and some places are very wet, which will affect the quality of fermentation.
2. Drying method:
Drying method is divided into mechanical drying method and natural drying method. Mechanical drying is a drying method using dryer, which can achieve the purpose of deodorization and sterilization. It is also a widely used drying method. The natural drying method is to mix the fresh cow dung alone or mixed with a certain proportion of bran, spread it on the cement floor or plastic cloth, turn it at any time, let it dry naturally, dry in the sun, then crush it, and mix it into other feeds for feeding. This method is low cost and easy to operate, but it is greatly affected by the weather and easy to cause environmental pollution.
3. Fermentation method:
The fermentation method is to add certain microbial agents or enzyme preparations and other auxiliary materials to cow dung, and then ferment at a suitable temperature, and the resulting products are used to feed chickens, pigs, fish and other animals. For example, if cow manure is fermented with silage, as long as there is enough water and soluble carbohydrates, cow manure can be silaged together with other poultry manure, crop straw, forage grass or other roughage. When silage, the ratio of manure and forage or other feed is preferably 1:1. This can convert part of non-protein nitrogen into protein and kill almost all harmful microorganisms.

2. Crushing and mixing of ingredients
The composted materials, inorganic fertilizers such as N, P, K, and other additives are crushed, proportioned and mixed by material crusher and horizontal mixer according to a certain proportion.
3. Granulation
A new type of organic fertilizer granulator was used to granulate the materials. https://www.fertilizerproductionprocess.com/fertilizer-granulator-machine-series/new-type-organic-fertilizer-granulator.html
4. Screening and return material system
The particle size output from the organic fertilizer granulator has a certain difference and needs to be sieved and classified. The selected rotary screener machine requires low vibration, low noise, convenient screen change, and is equipped with a screen surface cleaning device. It is recommended to equip a return system: the unqualified granular materials that are screened out are conveyed by a belt elevator, re-pulverized and sent to the granulator to continue granulation, which helps to improve the continuous operation capacity of the production line. https://www.fertilizerproductionprocess.com/fertilizer-screener-series/drum-screener-machine.html
5. Drying
Use an organic fertilizer drum drying machine to further remove moisture from the sieved particles to meet the standard requirements of organic fertilizer moisture content.
6. Cooling
Cooling the granular materials with a cooler helps the storage and quality of the granules.
7. Packaging
The granular materials cooled by the organic fertilizer equipment are conveyed into the finished product warehouse through the bucket elevator. Granular materials can be quantitatively weighed and packaged through automatic packing scale.
Production equipment and cost input of cow manure organic fertilizer
In addition to the initial equipment cost and civil engineering investment, the raw material cost, transportation cost, labor cost and packaging cost should be considered in the production process of cow manure organic fertilizer. If organic fertilizer plants cooperate with farms, the situation will be very different. In the original site where manure is stacked, greenhouses and fermentation tanks will be invested by the farms, and the organic fertilizer manufacturers will invest in purchasing equipment to deal with manure, which can also reduce investment or production costs. The organic fertilizer production realized the cooperation with the farm, and the capital investment was greatly reduced.
