A guide to maximising ball mill circuit classification ...

In this example the ball mill circuit classification system efficiency is 77.1 per cent at 75 μs. This means that 77.1 per cent of the particles in the mill are 'coarse' and that 77.1 per cent of the mill power is being used 'effectively'. Conversely, 100-77.1, or 22.9 per cent of the mill contents are 'fine' and are being ...

Ball Mill - an overview | ScienceDirect Topics

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING

environment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions: • The grinding of coarse particles; and, • The removal of the fine particles to make room for grind-ing more coarse particles in the ball mill. The overall efficiency of the ball mill circuit is therefore comprised of

Technical Feedback

III> Mill operation with very less ball charge. Mills operated at very less ball charge will not give the required output and recycling time to get the required finenees will increase. This is indicated by lower mill output, less power consumption, lower fineness percentage through 200 mesh. This situation also can lead for mill fires.
