Animal manure and wheat straw, such as cow dung, pig manure, sheep manure, and chicken manure, are all raw materials for the production of organic fertilizer. These raw materials are rich in mineral nutrients and organic matter. They are large in quantity and low in price, and can be used as organic fertilizers for a large profit. Organic fertilizer granulator is the key equipment for the production of straw manure organic fertilizer. It can convert these wastes into high nutrient, pollution-free fertilizer, and improve the quality of crops.
So how to choose the suitable organic fertilizer granulator?
Both the disc granulator and the drum granulator are granulated by the principle of agglomeration. The organic fertilizer granules made by them are spherical and have good appearance. They are suitable for granulation of organic fertilizer, compound fertilizer and other fertilizers. Disc granulator and drum granulator have certain requirements on the fineness of raw material powder, so the granulation effect of raw material containing more straw and other crude fibers is poor.
The new type organic fertilizer granulator is a special granulating equipment for organic fertilizer designed by our factory. The organic fertilizer granulator utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously realize the mixing and granulation of fine powder in the machine, thus achieving the purpose of granulation. This new type organic fertilizer granulator is suitable for the granulation process of most organic fertilizer materials.
Both flat-die granulator and ring-die granulator adopt extrusion principle to extrude organic matter into particles. Flat die granulator and ring die granulator have better granulation effect on organic fertilizer raw materials (straw, rice husk, cotton stalk, sawdust, cottonseed skin) with low bonding rate and poor forming conditions. Flat die granulator and ring die granulator extrude these raw materials into cylindrical particles, which can save a lot of energy. At the same time, in order to improve the appearance of the particles, ball polishing machine can be added after the granulator to make the particles smooth.
