Roll crushers are designed for crushing of coke and coal of different sorts with strength up to 18 on Protodyakonov scale, and for crushing of manganese ores, rocks and other minerals with strength up to 12 on Protodyakonov scale.

The crushers consist of 2 parallel plain, ridged or toothed rolls of the same size rotating towards each other. The material being crushed is fed through the charging chute to the operating space from above and is drawn by the rotating rolls in the space between them for crushing.

Toothed-roll crushers DDZE 9×9 and roll crushers DG 1000×550 have mechanical (spring) compression of rolls, other standard sizes of roll crushers are equipped with hydraulic compression of rolls. Toothed-roll crusher DDZE 9×9 is designed for crushing of coke and coal of different sorts. Two-rolled crusher with plain rolls DG 1000×550 is designed for crushing of materials with strength up to 18 on Protodyakonov scale. Two-rolled crushers with plain rolls DG 1000×600, DG 1000×900 and ribbed rollers DR 1000×600, DR 1000×900 are designed for crushing of manganese ores, rocks and other minerals with strength up to 12 on Protodyakonov scale.
