HPGR product has microcracked particles which weakens the boundaries and lowers the Bond work index. This reduces the amount of ball milling power required downstream. With a reduced load for the ball mills, you get a substantial reduction in required motor power, lowered steel ball consumption and increased grinding efficiency.

Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today the largest ball mill in operation is m diameter and m long with a corresponding motor power of 22 MW (Toromocho, private communications).

The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure ), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...

The feed enters one end of the ball mill, and discharges out the other end. Ball mills vary greatly in size, from large industrial ball mills measuring more than 25 ft. in diameter to small mills used for sample preparation in laboratories. Rod mills are similar to ball mills and use metal rods as the grinding media. Pebble mills use rock ...
