Ball mill size and power selection As discussed previously, ball mill circuit capacity could be increased by around 20 if cyclones are replaced with screens operating at high classification efficiency of 90 and low circulating load of 100 . This means that a ball mill selected in Step 1 of the design selection process would have 20 higher.The circulating load is a result of the ore hardness, mill power, powertherefore wear out evenly, a factor that is essential for high ball mill efficiency.with increase or decrease of circulating load.

The circulating load is recycled back to the ball mill for further grinding. 2.1. Mathematical model of grinding circuitsThe classical approach to the modeling of ball mills is the so called energy-size relationships . However, these relationships can only be used to predict an average product particle size.

Because the material that is ground to the specified fineness need to maintain a certain amount of detention time in the ball mill, and the coarse material in the ball mill will accumulate and , thus resulting in overage grind if the feeding capacity is not reduced timely. 3. Too much circulating load.Ball mill performance – is an indicator for showing the material amount passing through the mill per unit time.The drum mills productivity depends on the initial and final products size, the ore grindability, the mill size, the mill type, mill speed, the grinding balls degree filling, the circulating load value, and the classifier efficiency.
An industrial test work was performed to analyse the effect of applying a lower ball load and a finer ball size distribution in the second compartment of a KHD Humboldt Wedag ball mill on grinding and classification performance of a hybrid high pressure grinding roll (HPGR) multi-compartment ball mill cement grinding circuit. Mass balance of the circuit was done by JKSimMet Steady State.4 HIGH CIRCULATING LOAD If the cyclone keeps returning ore to the ball mill, the total volume of ore will be increasing in the grinding circuit, as is the density of the slurry. The recirculating ore is also called circulating load. If the grinding process becomes less efficient, the circuit.
Smaller values than those for ball mills in some points. This is due the wear of cyclones apexes and, consequently, the increase on vertical mill circulating load, which reached values over 500 by the end of the year. Unfortunately, due to the difficulty to access the cyclones of the vertical mill, its maintenance was compromised.Dec 26, 2017 Another factor that affects ball mill cement grinding efficiency and effectiveness as it relates to a specific material size distribution is the circulating load. It has been observed with increased circulating load and classifier efficiency there is an increase in the grinding efficiency.
