FIELD: mechanical engineering. SUBSTANCE: proposed rotary crusher contains housing, crushing chamber, rotor with crushing blades, detachable lining of housing made in form of staggered cones pointed by vertices into crushing chamber. Cone angle is less than double angle of friction in pipe lining-material under crushing pair. Each cone can be furnished in its base with cylindrical shank provided with thread on end orientated in axis of cone. Said shank can be fitted in hole of crusher housing and fixed by nut. EFFECT: reduced wear of lining material, its cost and labor input at replacing the lining. 2 cl, 2 dwg
