Flowing Rate Control. The flow rate of materials in the cement ball mill is controlled, and the partition in the ball mill is forced to pass through the compartment; the discharge grate plate ventilation area is adjusted to select the use proper scheme, and the hollow part of the activation ring is blocked to adjust the material flow rate.

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.
A mechanical classifier often receives its feed from a ball mill and produces (1) finished material which overflows to the next operation and (2) sand which returns to the mill for further sizereduction. The term "circulating load" is defined as the tonnage of sand that returns to the ball mill, and the "circulating load ratio" is the ...
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 ...
