THE DEVELOPMENT HISTORY OF VERTICAL CHAIN CRUSHER

Home / News / Blog

Compound fertilizer is the fastest growing fertilizer variety in my country in recent years. In the production of powdery and granular phosphate fertilizers and compound fertilizers, the selected crusher is mainly used for the crushing of raw materials and large and large semi-finished products, especially suitable for superphosphate, heavy superphosphate, compound fertilizer, ammonium phosphate, nitro Phosphate fertilizers, etc. typical. These materials are easy to absorb moisture and have high viscosity. In the crushing process, they are easy to stick to the inner wall of the casing, causing the machine to block, frequent shutdowns for cleaning, and the material stuck to the inner wall of the casing is hard and difficult to clean. The labor intensity of the operators is very high. Greatly affect normal production.

In order to solve the above-mentioned problems in the compound fertilizer production process, EMCC has developed this compound fertilizer vertical chain crusher. It has strong adaptability to materials with high water content, is not easy to be blocked, and the material is discharged smoothly. It overcomes the shortcomings of easy adhesion of the inner wall of the casing, frequent shutdown of the machine blockage, fast chain wear, short service life, and inconvenient replacement. And it has the advantages of convenient use, high efficiency, large production capacity, simple maintenance, etc., which enables continuous production in the crushing process and improves production efficiency.

Features of vertical chain crusher:

Vertical chain crusher is a machine based on impact crushing of brittle materials. It has a higher crushing ratio than the crusher based on extrusion. Under the action of the impact, the crushed material will often be broken along its weakest layer. With this selective crushing method, the probability of the particles being cube-shaped is relatively high.
Compared with the horizontal chain crusher, it overcomes the shortcomings of materials sticking to the inner wall of the cylinder during production, with high automation, flexible operation, low energy consumption, high production efficiency, and increasing market demand. Therefore, the research and development of this project is forward-looking. It also has the following characteristics:
1) The barrel of the crusher is made of high-quality Q235B steel plate, and the inner lining of the barrel is made of polypropylene plate, which is not easy to stick to the wall and easy to clean; the chain and chain plate are made of manganese steel, which is strong and wear-resistant, and has a long life.
2) The rotor, casing, and bearing chamber adopt a new type of sealing structure, which effectively solves the problems of dust leakage and dust entering the bearing chamber cavity to damage the bearing.
3) The crushing process adopts high-strength wear-resistant cemented carbide synchronous variable-speed chain. The design of the inlet and outlet is reasonable, the crushed material is uniform, not easy to stick to the wall, and easy to clean. 4) The compound fertilizer vertical chain crusher has simple structure, high efficiency and low cost; there are quick-opening inspection doors on both sides of the cylinder, which is convenient for maintenance and operation, easy for replacement of parts, and small maintenance workload.
5) Large production capacity, large crushing ratio, and strong adaptability to materials. Generally, brittle materials below medium hardness can be crushed, and the discharge port is large, and it is not easy to be blocked when the water content is about 20%.

The vertical chain crusher can meet the material crushing needs in the compound fertilizer production process in terms of structural design and practicality. At the same time, it can reduce labor intensity, improve production efficiency and automation, so it has a broad market prospect.
