Operating and Troubleshooting a Grinding Circuit

06.08.2015· You start to get a few rejects. Then the heavier density with the courser grind is pumped to the cyclone. Both the overflow and the underflow from the cyclone become heavier. Remember you now have a higher amount of ore that will have to be ground further. This causes the density of the ball mill to climb. Which in turn is discharged back to the cyclone. If now, you go back through the circuit ...

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the ...
