Crushers are designed for crushing oversized pieces of materials with dimensions up to 1.2 × 1.0 × 0.8 and a compressive strength of 40 MPa (strength factor 7 = 4 on the scale of Prof. M. M. Protodyakonov) and periodic crushing of waste rock with compressive strength of 70 MPa on the conveyor system of underground mining enterprises, as well as on the surface of mines of hard, brown coal, potash salts and other minerals.
