The fermentation process in the production of organic fertilizer is mainly to provide bacteria, auxiliary materials and temperature and humidity environment conducive to the fermentation of waste, so as to promote the rapid fermentation of livestock and poultry waste, and then through a certain granulation method to treat it, and finally get organic products rich in nitrogen, phosphorus, potassium and other plant nutrients.

When the Organic Fertilizer Production Line is running, the organic matter, urea and ammonia obtained from the fermentation of the reaction tower are added to the tray mixer in a certain proportion, and after being mixed evenly, they are sent to the pelletizer for granulation. The materials are formed into a mechanical fluidized bed at a certain speed in the pelletizer, during which an appropriate amount of steam is added. To provide the corresponding heat and moisture for the granulation process. Then an appropriate amount of circulating washing liquid is sprayed in the tail gas to promote the material to aggregate into particles.

Organic fertilizer granulator granulation molding system is to mix the raw materials after grinding, so that the material becomes particles. The granulator with stirring teeth can be used for granulation, which has the advantages of fast granulation speed and high efficiency. The disadvantage is that the forced extrusion pressure is small, and high-power crushing equipment is required. A Flat-Die Pellet Machine is also available. Its advantages are: wide adaptability to raw materials, especially strong adaptability to organic matter; Wide requirements on raw material density and raw material moisture, raw materials do not need to dry; Large roll diameter, template cocoa for positive and negative directions. The material is evenly distributed in the compression room, the granulation is stable, the granulation rate is high, the finished particles have a uniform appearance and are not easy to break; No water is added in the whole granulation process, which saves the subsequent particle drying cost; The requirement of fineness of raw material crushing is not high. Granulation raw materials (after composting) generally do not need to be finely crushed, and fine stone can be directly crushed. The disadvantage is that it is expensive to maintain.

When choosing a Granulator, in addition to a Flat-Die Pellet Machine, you can also consider Rotary Drum Granulator, which is suitable for mass production and can meet the needs of different raw materials.
