FIELD: machine building.
SUBSTANCE: invention relates to the device for processing of mineral material including outer and inner wearing parts. Inner wearing part comprises outer wearing surface including wearing surfaces of initial and final life stages and the ledge extending from the final life stage wearing surface. Note here that the final life stage wearing surface can be actuated vertically at the release from the initial wearing surface at increased wear. The initial stage wear wearing surface can make the grinding chamber along with the opposite wearing surface of outer wearing part. Note here that inner wearing part and ledge can displace vertically relative to outer wearing part. Invention relates to the device for processing of mineral material includes outer and inner wearing parts. Note here that inner wearing part is made in compliance with the above description to run eccentrically relative to outer wearing part. Claimed unit comprises the frame, bed secured thereto for independent displacement, material feeder and material crusher. Note also that said crusher comprises inner wearing part made as described above. EFFECT: longer life.
EFFECT: 11 cl, 10 dwg.
