The influence of mill speed and pulp density on the grinding

The best grinding efficiency measured in terms of Operating Work Index (Wio) or 'Kwh/T passing a certain screen' is obtained with the lowest speed. The extra power input obtained by increasing the speed does not have any effect and does not result in a finer grind. However, one should bear in mind that this testwork was

Media type effect on Grinding Efficiency

The consumption of energy in the grinding process is significant in both the amount used and the cost involved. Both imply that it is important to maximise the throughput for a given grinding task; which in turn implies it is important to maximise mill power draw, which is related to the efficiency whereupon this power is used.

2 Search for efficiency. It's been tried with combustion, and the general consensus is that 50% is the limit. In a fuel cell that figure jumps up to a possible 80%, but, considering that even the worst EV is roughly 80%-85% efficient, the limit could be far higher. McGeachie says: "It'd be difficult to see how an EV drivetrain as a whole

Grinding Medium

Tumbling ball mills are capable of fine grinding to around 20 μm with the energy efficiency increasing with decreasing media size, depending on the feed size. For feed sizes, P80, of 55 and 100 μm, Partyka and Yan [15] showed an increased efficiency with decreasing steel ball size from 36 to 5.5 mm in a ball mill.
