Powdered organic fertilizer refers to fertilizer produced by fermenting organic raw materials in a certain proportion without causing particles. There is a certain difference from traditional composting fermentation. The national standard is 40% organic matter, over 5% total nutrients, and 30% moisture. The equipment is also relatively simple, mainly consisting of three stages of fermentation: pre mixing, flipping, refining, and packaging.

The main purpose of the fermentation of powdered organic fertilizer equipment is to decompose the macromolecular materials of organic raw materials into small molecular materials that can be absorbed and utilized by crops through microbial decomposition. The quality of fermentation also affects the quality and effectiveness of organic fertilizers.

Powder organic fertilizer production line process: adding fermented products to the fermentation tank – evenly sprinkling bacterial agents – flipping fermentation – fermentation for 7-15 days – leaving the tank – screening – crushing – pre mixing – packaging (granulation can be added) – for sale.

Small and medium-sized powdered organic fertilizer production lines have low energy consumption, small footprint, no odor in the operating environment, zero pollution, good ventilation, and only 1-2 days for deodorization. The organic fertilizer production line has a compact structure and advanced technology. It uses harmless live bacterial preparations to treat livestock and poultry manure, and undergoes biological fermentation under the action of various beneficial microorganisms. After fully decomposing the organic matter, nutrients are released, and the resulting biological heat and high-temperature fermentation process can kill bacteria and insect eggs, detoxify and deodorize, purify the environment, achieve harmless, resourceful and industrialized treatment, low energy consumption, and stable product quality.

With the development of economy and technology, the breeding of animal husbandry has gradually transitioned from agricultural farming to farm farming. A farm raises tens of thousands or even hundreds of thousands of livestock. Scale farming can centrally manage livestock, reduce breeding costs, and improve meat quality. However, while the number of livestock increases significantly, there is also a problem of environmental pollution caused by waste. If these feces are not properly handled, they will affect the surrounding geological structure.

Granular fertilizer can add some inorganic components in fertilizer to improve fertilizer efficiency, while powdery fertilizer is easy to absorb moisture and caking if inorganic components are added. Granular fertilizer is more convenient to apply, especially in some large-scale planting bases, mechanical fertilization is generally used. If mechanical fertilization is used, only granular fertilizer can be used. If it is powdery, it is easy to fly everywhere.

Wet granulation is divided into many kinds of equipment, the early disc granulator, drum granulator, stirring granulator, organic fertilizer combination granulator and so on. Each granulation method is different for different raw materials, but it has one characteristic, that is, the moisture content of raw materials is generally 25% – 60%, and the requirements of moisture content are different with different equipment.
Disc granulator is an early granulation equipment for wet granulation. The moisture requirement is generally about 50%. The disc is used to make the materials roll on the disc and slowly stick together to form granules. It is suitable for relatively fine raw materials with low adhesion. Disadvantages: too high moisture, too much consumption in the later stage, and too high material requirements.
Among these granulating equipment, the most outstanding technology and performance are stirring teeth organic fertilizer granulator machine and organic fertilizer combination granulator machine. If it is pure organic matter granulation, it is recommended to choose stirring teeth granulation, which is suitable for a wide range of applications, and the water content can be controlled between 25% – 45%. Organic fertilizer combination granulator is mainly used to add some inorganic components (nitrogen, phosphorus, potassium, etc.) into the organic matter. The wet granulation material requires high moisture, and the consumption of drying and cooling is increased.

The organic fertilizer drum screening machine is tilted and installed on the frame. The motor is connected to the drum device through a reducer and a coupling, and the drum device is driven to rotate around the shaft. When the material enters the drum device, due to the tilting and rotation of the drum device, the material on the screen surface is flipped and rolled, allowing the qualified material to be discharged through the discharge port at the rear end of the drum, and the unqualified material to be discharged through the discharge port at the end of the drum.
