Abstract

1,207,655. Conical mills; disc pulverizer's. J. M. VOITH G.m.b.H. 25 April, 1969 [25 April, 1968], No. 21166/69. Heading B2A. Grinding tool, e.g. a disc 1, or conical plug and shell 10, 20 for a difibrator has a working surface as at 1a. Fig. 1, having projections 2 or 12, 22 whose height is at least one and a half times the width of the projections measured at their tips, the grooves 3 or 13, 23 between the projections being in part filled with plastics material 4 or 14, 24 introduced in liquid, paste or powder form and then cured or set. An epoxy resin with a talc filler may be used. When worn down, the plastics is removed and a new filler may be poured in. When further wear takes place, this material is removed and the original casting used alone. The life is thus prolonged.
