The production process of chicken manure organic fertilizer processing: Organic fertilizer production enterprises will use dedicated vehicles to regularly collect chicken manure from various breeding farms to avoid secondary pollution to the road surface. The collected chicken manure will be directly sent to the fermentation area. After one fermentation, two aging and stacking. Firstly, the odor of chicken manure was eliminated. During a fermentation process, plant stems and leaves such as straw, plant leaves, and weed powder should be added in proportion. At the same time, fermentation strains should be added to decompose the coarse fibers, so that the particle size after crushing meets the particle size requirements of granulation production.

Working principle of disc granulator: It is mainly composed of an angled disc and a base, which can be adjusted. During the granulation process, the material mixed by the mixer is sent to the top of the disc by a conveyor, and continuously and quantitatively added to the disc. The material inside the disc is adhered and wrapped into granules by the adhesive sprayed on it. As the disc rotates, the particles gradually grow. Due to the significant grading ability of the machine, large particles float on top and continuously flow out from below the disc, while small particles continue to grow with the newly added material. This machine has the characteristics of uniform granulation, low particle return, and high production capacity.

1. Precautions for disc granulator: The granulator should operate in the forward direction; Avoid reversing. The granulator should not be operated on an empty stomach while cooling. It must be operated on a hot machine for feeding to avoid sticking to the shaft. It is strictly prohibited for iron or other debris to enter the feed inlet and vent hole of the granulator. To avoid accidents and affect production.

2. Precautions during the operation of the granulator: always pay attention to changes in the body temperature. When touching the strip with clean hands without touching them, immediately raise the temperature. Until the strip touches the hand, it is normal. When the bearing part of the reducer burns or is accompanied by noise, it should be repaired in a timely manner and refilled with oil.

When the bearing parts at both ends of the host bearing chamber become hot or make noise, the machine should be stopped for maintenance and butter should be added. During normal operation, grease should be added to the bearing chamber every 5-6 days. Pay attention to understanding the operating rules of the machine; For example, the temperature and speed of the machine can be dealt with in a timely manner according to the situation. When the operation of the aircraft is unstable, attention should be paid to checking whether the clearance between the couplings is too tight and adjusting it in a timely manner.

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 other trace elements to the mixing and stirring system, start stirring, and transport the mixed materials to a disc granulation system. After being dried in a dryer, enter the cooling system and sieve the materials until they reach room temperature. The particles that meet the requirements enter the coating machine for coating and packaging. The particles that do not meet the requirements are crushed by the crusher and returned to the organic fertilizer granulation system for further granulation. After the above procedures, chicken manure has become the main raw material for organic fertilizer and is directly sold in the sales market.

The new type of organic fertilizer granulator utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously mix, granulate, spheroidize, and compact fine powder materials inside the machine, thereby achieving the purpose of granulation. The particle shape is spherical, with a sphericity of ≥ 0.7, a particle size generally between 0.3-3 millimeters, and a particle yield of ≥ 98%. The size of the particle diameter can be adjusted appropriately by the material mixing amount and the spindle speed. Generally, the lower the mixing amount and the higher the speed, the smaller the particle size, and vice versa. Application scope: This machine is particularly suitable for granulation of lightweight fine powder materials. The finer the basic particles of fine powder materials, the higher the sphericity of the particles, and the better the quality of the formed balls. It is generally required that the particle size of the material before granulation should be less than 200 mesh. Typical application materials include chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc. It is generally required that the particle size of the material before granulation should be less than 300 mesh. Typical application materials include chicken manure, pig manure, cow manure, charcoal, clay, kaolin, bentonite, chemical raw materials, compound fertilizers, compound fertilizers, etc.
