Our Case### THE OPTIMAL BALL DIAMETER IN A MILL

Let us look back at the optimal ball charge in a mill. The necessary number of balls having the definite diameter N b in a mill should be proportional to grain number N having the definite diameters which they can grind: N b ~ N. (7) The number of grains of the material with determined diameters depends on the grain size distribution. For a great number of materials the grain size distribution at the

### Ball Mill an overview ScienceDirect Topics

The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds.

### Ball Mill: Operating principles, components, Uses

11/01/2016· A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse

### SAG Mill Ball Sizing Grinding & Classification Circuits

Optimum ball charge in a SAG mill is a function of many factors. Some are discussed below. For a SAB or SABC circuit. In general, the higher the ball charge the higher the throughput (and fine feed helps as well). Of course, you need a bigger ball mill. But, high ball loads mean higher ball consumption in the circuit. Many ores can be amenable to autogenous milling, but getting it right without piloting can be

### MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING

In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill.
