High fineness, high output screening mill technology is a technology improving grinding efficiency for the ball mill. The new screening partition plate with the function of separating is installed in the mill to reduce over-grinding condition. The micro grinding medium is used to increase grinding efficiency. The removable liners and flow speed control measures are taken to strength grinding operation. Thus it achieves the goal of output increasing and energy saving.
The technology obtained U.S. Invention Patent, China Invention Patent and 2nd award of Scientific and Technological Advancement at the State Level. It has been successfully applied to more than 1000 sets of mills, which has brought good economic and social benefits.
