Four Roller Crusher

详情

Summarize  

Quad roller crusher suitable for the solid material(compression strength less than **0Mpa,humidity less than *0%)  to proceed fine crushing. Such as coal, coke,  ceramics raw materials,mine,grain slag,Gypsum,clay,salt,chemicals and other solid materials.

Features: low use and maintenance costs,high ratio of reduction, high reliability, low dust , low noise.

 The four rollers of quad toothed roller crusher are divided into overlay welding rollers or flat rollers,according to the discharge size requirement to combination, It is suitable for the materials(feed sizeis less than *0mm,discharge size required 0.2mm**0mm) to proceed  fine crushing.Such as steel,industry crushing coke;Quartz industry crushing quartz stone;Iron industry crushing iron ore;or in the similar occasion as above.
 

Principle of work

Four roller crusher is fixed with four high-strength wear-resistant alloy grinding rollers. Their relative rotation makes high extrusion pressure and shear force for crushing the material. Firstly the material is entered into the space between the top two rollers. Here, it is extruded, rolled and sheared (rough broken) because of the rotation of the top two rollers. Then, it is secondly extruded and gnawingly milled (fine crushing) by the middle two rollers which are relatively rotating. Finally, under the extrusion, cut and mill of the next two rollers, the material becomes the required size, sent by the transport equipment.
