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.

grinding the Pc pigment in water using a media mill. Mostly, dispersions of Pc in water are used in heat-set inks to make the color phthalo blue. Typically, Pc slurries are 40-50% solids and ground with steel media (spherical beads) to produce a stabilized dispersion with 99.9 percent of all solid particles less than 0.5 microns in size.

Ratio of grinding mill loading by grinding balls. Ratio of grinding balls volume to mill working volume is calculated by the formula: where: G н – mass of grinding balls, kg; γ – apparent density of grinding media, kg/m3; L – drum length, m. Apparent density of grinding media depends on ball diameter and density of the material.

Relief is usually not noted until polishing begins, so it is important to begin the preparation with grinding media that will keep the samples as flat as possible. However, for the best possible starting conditions, MD-Largo should be used for fine grinding of materials with a hardness below 150 HV, and MD-Allegro should be used for fine ...
