The ore materials crusher (double-roll crusher) excels in the field of mineral material crushing, particularly suited for medium and fine crushing operations of medium to low hardness ores. It functions like a precision surgical scalpel. 1. Working Principle The double-roll crusher generates high-pressure squeezing forces ranging from 50 to 200 MPa through two counter-rotating rollers (smooth or toothed surfaces). This force draws ore into the gap between the rollers, where it undergoes compression and shear crushing.
