Double roller crusher can adjust theclearance between rollers and drive through triangle belt or multidirectionalshaft coupling, and the four roller crusher will do it only through triangle belt.
double roller crusher is widely used inmining, coal mining, can adjust the clearance between two rollers for thedischarging.
Double roller crusher is mainly used forthe crushing of medium or lower-hardness mines and rocks with medium or lowerrigidity in mine selection, chemicals, cement and building materials industrialproduction.
Double roller crusher Working Principle :
Through the feed opening, the raw materialsfall to between the two rollers, after crushed, the final products dropnaturally. When there are unbreakable materials or the material is too hard,the roller will concede automatically under the effects of spring and hydraulicpressure, which will widen the clearance between the rollers and make the hardor unbreakable so as to avoid damaging the machine. The clearance between thetwo rollers can be adjusted to change the sizes of final products.
