Formula For Grinding Mill Circulating Load
Procedure for determination of ball Bond work index in …
The number of revolutions in the second grinding cycle is calculated so as to gradually produce the 250% circulating load. After the second cycle, the same procedure of screening and grinding is continued until the test-sieve under size produced per mill revolution becomes constant for the last three grinding cycles.

Closed circuit ball mill – Basics revisited
1. Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product).

A guide to maximising ball mill circuit classification …
Calculate the CSE as the average: (80.7 + 73.5) ÷ 2 = 77.1% + 75 μ. 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'.
