Working principle:
Roller crushers have a theoretical maximum reduction ratio of 4:1. If a 2 inch particle is fed to the roller crusher the absolute smallest size one could expect from the crusher is 1/2 inch. Roller crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm). A crushes using compression, with two rollers rotating about a shaft, towards the gap between the rolls.  

Introduction of coal crusher

The coal crusher can be used for intermediate and fine crushing such hard and medium hard ore and rock in mineral separation, chemical industry, cement, corhart, abradant materials, building materials and other industrial department, especially for producing rice-like and bean-like stone. Its effect is more excellent than common crushing equipment. We can provide you not only the roller crusher and all of accessories, but also type selection introduction and installation guidance, etc.
