FIELD: machine building.
SUBSTANCE: group of inventions refers to horizontal roll crusher and method of crushing in it for grinding of mineral materials and/or materials during cement clinker production. Crusher (1) with material layer (5) compression contains drum (2) with horizontal axis (A) and drive. Drum internal wall comprises crushing roller (3) rolling track (20) inside drum. Grinding roller axis is parallel to drum axis. In crusher grinding roller to raceway pressing facilities are fitted. Input for loading and ground material output are located at different drum ends. Leveller roller (4) is located before crushing roller in drum rotation (R) direction. Near and at distance from raceway leveller roller retainers (6) are located. Retainers are made with possibility to prevent any contact between leveller roller and raceway. During each drum revolution material is successively passed under leveller roller and under crushing roller. Retention and pressing devices make leveller roller possible to act on material layer with pressure. Leveller roller pressure aligns material surface. Leveller roller pressure on material layer is lower than grinding roller pressure (P).
EFFECT: longer service life of crusher.
