Grinding control strategy on the conventional milling circuit

There are six parallel conventional milling circuits at Palabora Mining Company. Each milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (-9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first

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

Ball Mill vs Rod Mill | How To Choose Ball Mill or Rod

In coarse grinding, when the product size is 1-3mm, the processing capacity of the rod mill is greater than that of the ball mill(usually the feed size of rod mill is 15-23mm). In fine grinding, when the product size is < 0.5mm, the grinding effect of the ball mill is greater than that of the rod mill(The feeding particle size of ball mill is generally 5-25 mm).
