Understanding the Use of Ball Mills in Wet Grinding

Wet mills are designed as overflow mills and they are often operated in closed or open grinding circuits. Description. A ball mill is made up of a cylindrical shell which is hollow and rotates around its axis. The shell's axis could be horizontal or could be positioned at a small angle to the horizontal. A part of it is filled with balls.

The operating principle of the ball mill

Cascade mode motion of grinding balls carried out at low drum speed. At start-up of a mill, the grinding material rotated by a certain angle and grinding balls start to move by closed path. The curved surface of natural slope is close to the plane inclined at some angle to the horizontal. This angle is equal to a limit angle of rotation.

Generally, a maximum allowed ball size is situated in the range from D /18 to D /24. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed 30–35% of its volume.
