Main Equipment for Fertilizer Production - Crusher

With the popularization of scientific fertilization, the production of compound fertilizer has developed rapidly. The production process of solid compound fertilizer mainly includes crushing-mixing-granulating-drying-screening-packaging and so on. The corresponding complete production equipment mainly includes crushing equipment, mixing equipment, granulation equipment, drying equipment, screening equipment, conveying equipment and packaging equipment, if the production of organic fertilizer and biological fertilizer also includes fermentation equipment.
This paper mainly introduces the crushing equipment of fertilizer. In the production of compound fertilizer, there are different granularity requirements for raw materials according to different processes. In order to accelerate the reaction speed, improve the uniformity of raw materials and facilitate granulation, it is often necessary to further crush the raw materials; in the production process, unqualified large particles or bulk materials also need to be crushed and returned to the granulation system, so different types of crushing equipment are needed. The main types of crushing equipment are chain crusher, cage crusher, half wet material crusher, etc.

The cage crusher uses the cage bar on the high-speed rotating rotor to strike the material to realize the material crushing. It is widely used in the production line of coal and compound fertilizer plants. Cage type crusher is middle size horizontal cage bar crusher, which can crush simple fertilizers that is less than 6% water content, especially applied to high rigidity materials. It is simple and compact in structure, cover small area, easy maintenance such characters, crushing effect is good, smooth operation, easy to clean. It is a professional equipment for crushing ammonium dihydric phosphate, ammonium phosphate, urea and other materials.
Fertilizer Crusher

Half wet material crusher is a professional equipment for crushing multi-fiber materials with high moisture content. Half-wet material crusher uses high-speed rotating blades to crush fibers with good particle size, high efficiency and high efficiency. Half-wet material grinder is mostly used in the production and processing of organic fertilizer. It has good effect in crushing chicken manure, humic acid sodium and other raw materials. The machine has played a key role in shortening the process of bio-organic fertilizer and composting production, reducing equipment investment and saving operation costs.
Half wet material crusher has a high grinding fineness and a moisture allowable value of 25-50% for bio-fermented organic fertilizer materials. It can also be adjusted in a certain range according to the needs of users. It plays a role in grinding hard materials such as ceramics, bricks and gravel in municipal solid waste, and is an ideal machine for fertilizer production and processing units.
Application scope :
Treatment of chicken manure, duck manure, cow manure after fermentation
crush of sludge and biogas residue
crush of municipal solid waste

Chain crusher is suitable for crushing the large material on compound fertilizer production line, crushing before granulation and crushing after returning materials. But also widely used in chemical industry, building materials, mining and other industries. 
Chain crusher is divided into vertical chain crusher and horizontal chain crusher according to the installation form. The vertical chain crusher is a single rotor and the horizontal chain crusher is a double rotor. This machine use high-intensity wear resisting and cemented carbide chain plate with synchronous speed, and it has reasonable design for entrance and out quarrel, so which results in such advantages: fully broken, difficult to stick wall, easy to clean.
