Mill Discharge: • In continuous mill to avoid buildup of material rate of discharge=rate of feed • Discharge rate must be such that the working parts of the mill can operate most effectively on particle. • If particles are crushed more than necessary, then more energy will be wasted. This type of crushing operation is called choke crushing.

Wet ball mills were being tested on the gold ores in South Africa and copper ores in Arizona and the Dorr classifier made continuous closed circuit grinding a reality. The ball mill – rake classifier circuit (spiral classifiers were also used) were used for 50 years until the development of better pumps enabled hydrocyclones to replace

On the basis of the batch tests, continuous- grinding-circuit flowsheets were designed. The basic components of the continuous open-circuit and closed-circuit grinding plants were essentially the same as in the smaller scale tests. In the larger closed-circuit plant, however, a 6-inch-diameter, solid-bowl centrifuge was used as a classifier.

Closed-circuit Grinding System. The closed-circuit grinding system of the ball mill is shown as follows: materials mixed in a certain proportion will firstly enter the cement ball mill for grinding and then be sent to the powder concentrator by bucket elevator. The powder concentrator divides the materials into coarse and fine materials.

ABSTRACT An industrial ball mill operating in closed-circuit with hydrocyclones was studied by five sampling surveys. The aim of the present study was to optimise operating parameters (i.e. charge volume, make-up ball size regime, slurry mean residence time, number of hydrocyclones in operation and hydrocyclone’s feed solids content (Sf)) with respect to increasing throughout from 225 to 300

The mill is a side drive as you refer to and the seals are of the twin lip type. We definitely have an issue with seals because of the amount of contamination in our oil. The tin content I assume is from the white metal bearings. It varies quite considerably with each sample, but is a real worry.

The characteristic differences between open- and closed-circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product, the rate of powder production in the closed-circuit is about 5% higher than that of the open-circuit.
