Abstract

1380954 Impact pulverizers NIPPON STEEL CORP 4 April 1972 [1 April 1971 9 Aug 1971] 15447/72 Heading B2A An impact pulverizer enploys a rotor having blades 7, Fig. 14, intercalating with cooled screen or impact bars 1. These each comprise a jacketted chamber within the bar connected to cooling meduim supply and exhaust pipes 4, 5, the bar having a wear resistant facing. The bar may comprise plates 8, 9, 11, 11', Fig. 8, a preparator plate 14, a facer 16, and a facer 17 to protect the outer side face 10. A caplike protection plate 23 may cover the top of a bar, Fig. 11. In the embodiment of Fig. 14 the part subjected to most wear, viz. the crushing cap itself is water cooled. The cap 2 is made of, e.g. a heat treated Nickel-Chromium alloy steel. A further cap 3 at the end of the bar 1 is not subject to such severe wear and not made of a wear resistant alloy, but is partially water cooled by covering and protecting the pipes 4 and 5.
