Ball mill
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. An internal cascading effect reduces the Abstract: The first large gearless ball-mill in North America has been successfully installed at the Mississauga, Ontario, plant of the St. Lawrence Cement Company.

Ventilation Prediction for an Industrial Cement Raw Ball Mill by
1. Introduction. In the cement industry, grinding is one of the most consuming energy stages in the production units. Around 65% of the total used electrical energy in a cement plant has to be utilized to grind raw materials, coal, and clinker [1,2].Through the process, many variables can affect the efficiency and productivity of Generally, filling the mill by balls must not exceed 30%–35% of its volume. The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length.
