The Three Types of Ball Mills - Minerallurgy

Ball mills are usually either of the grate (diaphragm) or overflow type. Ball Mill Components. Ball mills consist of the following components: Inlet – crushed ore is fed to the ball mill through the inlet. A scoop ensures the feed to the mill is constant. Discharge – reduced feed exits the mill through the discharge. Ball Mill Components

The Three Types of Ball Mills - Minerallurgy

The overflow type of Ball Mill is designed to overflow and discharge materials from the trunnion on the outlet side. By combining it with a mechanical classifier or wet-processing cyclone, you are able to extensively use this type for grinding in closed circuit or for special applications such as re-grinding in open circuit.

Converting a ball mill from overflow to grate discharge ...

If a mill has available power, conversion of the discharge arrangement from overflow to grate can be beneficial in allowing increased throughput or a finer product size. Conversely, if the mill does not have available power then it is still possible to install a grate discharge and to draw the same power by using a lower ball charge.

Ball Mills - Mine Engineer.Com

Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral ...
