Ball mill Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

The abrasive used for each succeeding grinding operation should be one or two grit sizes smaller than that used in the preceding step. A satisfactory fine grinding sequence might involve SiC papers with grit sizes of 240, 320, 400, and 600 grit [P280, P400, P800 and P1200]. This sequence is used in the “traditional” approach.

OSHA Silica Rule Misconception of Glass Dust TERRAZZCO

Dec 08, 2017 To best understand silica, we must address where it comes from and how it is formed. Silica makes up most of the Earth’s crust. 100 times smaller than sand, silica is not visible to the naked eye. Today silica is found in many building materials, with dust forming by cutting, grinding, or drilling these materials on the construction site.
