This promotes people to study and develop the ball mill system with smooth start, high grinding efficiency, high output and low consumption. This is exactly the VFD control system. II. Working principle of the ball mill The ball mill is mainly constituted by cylindrical barrel, end cap, bearing and transmission big gear ring and other components.
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.
