    In order for the ball mill to perform normal grinding operations, its working speed must be less than the critical speed. Ball mills generally work in a “dropped” state. There are many working speeds to achieve this working state, but there must be the most favorable working speed. 1. If the rotating speed is low, the ball in the ball mill

    Maximum efficiency. Liner wear is directly correlated to the ore trajectory in a grinding mill for a given RPM. As the liners wear, the ability to strike the toe at higher volumetric fills may not be possible. In cases where this is true, the volumetric load will automatically be decreased until the toe is impacted, thus restoring maximum

    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
