Ball Mills And Ball Charging Bulk Handling Technologies

Grinding is the process of achieving particle size reduction through attrition and compressive forces at the granular level. The grinding media in a ball mill is typically steel or ceramic balls of varying sizes, depending on the feed size, work index of the ore and the size reduction and distribution required in the discharge.

Advanced Controller For Grinding Mills

The ball mill is in closed circuit with a sump and three cyclone classifiers. The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. The slurry from the ball mill is pumped out of a sump into two cyclone separators. The underflow from the cyclone is returned to the ball mill. Balls are added periodically to the mill on a per shift basis or when the power draw drops below.
