Compared with chemical fertilizer, bio organic fertilizer has a high content of organic matter, which is particularly suitable for land reclamation and soil improvement. Bio organic fertilizer has a wide range of applications, including all kinds of food crops, cash crops, organic farms, etc., which have a high demand for bio organic fertilizer. Moreover, the food and vegetables produced by applying bio organic fertilizer have a better taste. If used on cash crops such as tobacco leaves, it can significantly improve the grade evaluation of tobacco leaves, so it is welcomed by farmers. When livestock and poultry burned products are built into organic fertilizer, they can generally be sold for 600 ~ 800 yuan / T. by comparison, the environmental trend price of general compound fertilizer is around 1200 ~ 1800 yuan / T, so organic fertilizer has the inevitable cost advantage, and the prospect of environmental trend is very broad.

Agitated organic fertilizer granulator is one of the link equipment in the organic fertilizer industry, which is suitable for cold and hot granulation and large-scale manufacturing of high, medium and low concentration compound fertilizers. The important working method is wet granulation of pellets, which experiences a certain amount of water or steam, so that the chemical feedback is sufficient after the base fertilizer is humidified in the cylinder. Under the premise of a certain liquid phase, with the help of the twisting action of the cylinder, the material particles are extruded and rounded into balls. The cylinder of the machine accepts extra rubber plate lining or acid resistant stainless steel lining, which voids the ancient scraper assembly.

The double roll extrusion organic fertilizer granulator is an improved product that absorbs the new technology of international granulator. The machine is equipped with a pre continuous feeder with machine touch assembly and a feeding system connected with a forced feeding screw hopper, which ensures the continuity, sufficiency and symmetry of feeding, which is a crucial step. Evenly distributed arc grooves are carved on the paired rolls, which is beneficial to the biting of materials into the rolls, the formation of arc groove sealing cavity (belt) during work, and also beneficial to the compaction of materials, reducing the forming pressure of the mechanism and the load of the host machine, and improving the manufacturing rate of rolled sheets.
