The equipment for producing 100000 tons of organic fertilizer annually usually includes fermentation equipment, crushing equipment, mixing equipment, granulation equipment, drying and cooling equipment, screening equipment, and packaging equipment. The following is a specific introduction:

1. Fermentation equipment: The trough fermentation turning machine is a commonly used equipment, suitable for the fermentation turning and pushing of organic waste such as livestock manure, sludge, and garbage. It can be used in conjunction with solar fermentation chambers, fermentation tanks, and transfer machines, and can achieve the function of using one machine for multiple tanks. Its control cabinet is centrally controlled and can be manually or automatically controlled. It is equipped with a soft starter, which has low starting impact load.

2. Crushing equipment: The semi wet material crusher is used to crush the agglomerated materials after fermentation to a particle size that meets the requirements. Generally, the crushing particle size is required to reach 50 mesh granulation requirements. This equipment allows the moisture content of organic fertilizer materials for biological fermentation to reach 25% -55%, which can solve the problem of crushing high moisture organic matter.

3. Mixing equipment: The horizontal mixing mixer is a new generation of mixing equipment with high mixing uniformity and low residue, suitable for mixing compound feed, concentrated feed, and additive premix. It adopts a novel rotor structure, and the gap between the rotor and the shell can be adjusted to near zero, effectively reducing the amount of material residue. The machine is also equipped with a grease addition pipeline, making the overall structure more reasonable, the appearance more beautiful, and the operation and maintenance convenient.

4. Granulation equipment: The new organic fertilizer granulator utilizes high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously achieve mixing, granulation, balling, densification and other processes of 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 formation rate of ≥ 90%.

5. Drying and cooling equipment: Rotary dryers are used to reduce the moisture content of particles to below 15% to prevent mold growth, usually using hot air circulation technology; The rotary cooler can quickly cool the particles to below 40 ℃, avoiding particle agglomeration.

6. Screening equipment: The drum screening machine is used for grading and screening finished particles. It can be equipped with a first level screening machine and a second level screening machine to increase the yield of finished products and improve the quality of particles.

7. Packaging equipment: The automatic packaging machine includes electronic quantitative packaging scales, silos, automatic sewing machines, etc., which can achieve quantitative packaging of 25kg/bag or 50kg/bag with an error of ≤± 0.2%.
