FIELD: design members of device for crushing, grinding and conveyance of mineral raw material, applicable in mining concentrating, construction, chemical and other branches of industry. SUBSTANCE: the lining has plate 1 made of wear- resistant alloy and pad 2. Plate 1 has holes 3 distributed on its working surface 4 and closed with pad 2. Lumps of rock and working medium, retained in holes 3, self-line plate 1, due to which the wear of plates 1 is reduced. Worn-out plates 1 are replaced, and pads 2 are used many times. EFFECT: enhanced utilization factor, reduced maintenance costs. 2 cl, 2 dwg2
