Roller crusher Overview
1 Brief Introduction
Roller crusher is mainly used for secondary and fine crushing to materials below middle hardness, such as coking coal, clinker mineral, limestone, metallic and nonmetallic ore. Roll crusher is available for ore dressing, chemical, cement, refractories, abrasive, building materials industries, finely crushing all kinds of ore and rock below the high, medium hardness,which can make the minimum grain size below 100 mesh,especially in the building materials industry to produce melon meters stone and green bean products etc, and have the more excellent effect than general stave machinery , in recent years, also widely used in crushing steel grit industries.
2. Structure info.(Including Base Materials)
Roller crusher is mainly combined by foundation, frame, crushing rollers, shafts, adjusting device, protective springs, pulleys.

3.Finely crushing all kinds of ore and rock below the high, medium hardness,which can make the minimum grain size below 100 mesh;
4.Roller crusher is stable operation, easy maintenance, low cost, output size adjustable.
4. Working Principle of Roller crusher
Adjustment of the discharging materials: wedge-shaped or gasket adjustment device is installed between the two rollers; adjusting bolt is installed on top of the wedge-shaped device, and when the wedge is pulled up by the adjusting bolt, it will push the dynamic roller pulley away from the fixed pulley, thus making space between the rollers wider and particle size bigger;
when the wedge moves down, the dynamic roller pulley is pressed by the hold-down spring and then the space gets smaller as well as the particle size. The gasket device works depending on the adjustment of the number and the thickness of gaskets. When adding more gaskets, space between rollers and the particle size will become big; vice versa.
