Separation Efficiency - Metallurgist & Mineral Processing ...

The Separation Efficiency meets all the usual requirements of a true efficiency and is independent of the nature of the process used. It can be visualized as the percentage of the feed material that, in effect, actually undergoes complete separation while the rest of the feed is distributed randomly and unchanged into the two separation products.

What is the screening efficiency | magnetic separators

How to calculate? The screening efficiency is the ratio of the weight of the grain size smaller than the mesh size, ball mill in India screening products under the weight of the screening actually get into the sieve material contained within is generally expressed as a percentage. The formula E = [100 (a-b)] / a (100-b)] ¡Á .
