static charge ball mill in kenya

May 28, 2008 · When friction is applied in a ball mill, that is literally a recipe for binding two substances together with static electricity. But something else also happens to the fumed silica inside the ball mill: The fragile strands of nano-spheres are crushed and broken into tiny pieces. The resulting tiny pieces are considerably smaller than a spore

    Apr 01, 2001 · The ball mill is 13-ft-6-in diameter by 18-ft, and was originally intended for a rod mill application. It has a large diameter trunnion and an oversized motor. To bring the ball mill speed up to 75% of critical from 66%, the 24-tooth pinion was replaced with a 27-tooth one. Equipment selection using SPI data was deemed a success
