The roller crusher can be used to finely crush various high and medium hardness ores and rocks in industrial sectors such as mineral processing, chemical industry, cement, refractory materials, abrasives, and building materials, especially for the production of guar and mung bean sand in the building materials industry. The feed size is large, and the output size is adjustable, which can crush materials with compressive strength ≤160MPa. Especially used in the coal industry, this machine crushes raw coal. It can be crushed directly after iron removal, impurity removal, and no gangue removal. The crushed material has a uniform particle size, which simplifies the coal preparation process and reduces investment and production costs...Learn More
