PURPOSE:To improve workability and economical availability as well by mounting a liner on a body as compressed, which many result in keeping the body from being exposed to a seam and also the liner unnecessary for having a rubber plate mounted on the lower side. CONSTITUTION:A rubber plate 2 and a lifter bar 4 are mounted, as compressed, between a fixed member 6 and a projection 7 of a mill body 1. Then, a rubber plate 3 and a lifter bar 5 are also mounted, as compressed in the direction butted each other, between the fixed members 6, 6. Therefore, a compressive stress alpha works on ends of the fixed member 6 which form a seam 8 with the rubber plate 3 or the lifter bar 5, a seam 9 between the rubber plates 3 or the lifter bars 5 and a seam 10 between the rubber plate 2 and the fixed member 6 or the projection 7, the ends come in contact full with each other to prevent a material to treat from incoming, and portions of the seams 8, 9, 10 come to wear uniformly. |
