1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.
recorded as 17 per cent. The new. ball size distribution did not change. the power draw of the mill, but. the mills production capacity was. increased from 115tph to 150tph. at the same quality figures. The energy consumption fell. from kWh/t to kWh/t.
The ball mill maintenance period can be divided into 36 months for minor repair, 612 months for medium repair and 60120 months for major repair. In the daily operation process, we should also pay attention to the ball mill maintenance. These are the basic maintenance conditions

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 ...
