Ball Mill Circulating Load - Mineral Processing

09/10/2015  As the circulating load increases, typically the cyclone underflow density increases, causing the density and viscosity in the mill to also increase. This can lead to excessive mill viscosity, causing the balls to float, leading to a sharp drop in the power draw. The operator can be misled to conclude that the mill is overloaded due to the higher circulating load. The operator will usually sharply

Factors Affecting Ball Mill Grinding Efficiency

c) Closed Circuit Grinding – Also closely related to the ability of a ball mill to perform most effectively on a particular material size distribution is the increased grinding efficiency observed with increased circulating load and classifier efficiency. Increased circulating load decreases overgrinding and provides the media with an effectively narrower size distribution to work on. However, it meets with diminishing returns in

Circulating Load Calculation Formula

Why have a large circulation load: If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70). In practice, circulating loads between ball mills and classifiers are rarely less than 200 per cent and

Ball Mills - Mineral Processing Metallurgy

Grate Discharge Ball Mill: This type of mill usually works with a high circulating load and thus produces very little extreme fines. The specific power consumption is therefore less than for an Overflow Mill. A Grate Discharge Mill will also have 15—25 % higher capacity per volume unit as compared with an Overflow Mill. The discharge trunnion can be furnished with trommel screen.
