  • The working principle of ball mill - Meetyou Carbide

    May 22, 2019  The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.

    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 steelballs. An internal cascading effect reduces the material to a fine powder. Industrial ball mills can operate continuously, fed at one end and discharged at the other e

    Speed of MillMedia and Product LoadingType of Grinding MediaSize of Grinding MediaBack in the old days, operating speeds where obtained through trial and error. Now, we are able to determine practical operating speeds by using the formula 54.19 divided by the square root of the radius in feet. Faster RPM are required for smaller mills to reach critical speed.To minimize any grinding or dispersion issues, we aim for the cascading action discussed prior. The most desirable angle to accomplish this falls between 50 to 60° from horizontal. The lower end of this range applies t...
