ContactOur cast iron grinding balls can be divided into three categories including the high chromium type, medium chromium type and the low chromium type. 1. The Quality Index of the High Chromium Type The chromium content of the high chromium type product is greater than or equal to 10.0%. And the carbon content is between 1.80% and 3.20%.
ContactA manufacturing technology has been developed for wear-resistant cast-iron grinding balls without shrinkage defects. In this method, the balls are cast in single-use sand–clay molds. A new approach to designing the casting system is developed. By numerical modeling, the time dependence of solidification is derived. As a trial, grinding balls are produced by the proposed technology.

Contact1997-4-1 The molten fluidability is good enough to cast grinding balls as long as CE is over 3.0. To decrease the manufacturing cost, manganese rather than Ni, Mo, Cu etc. is added to the cast iron to improve the hardenability; this is not the same as austempering ductile irons, because manganese is
