The cluster was installed and commissioned within two days. At the start of the project, the incumbent competitor hydrocyclone cluster's overflow mass flow rate was approximately 50 t/h. The Cavex 250CVX eightcyclone cluster, on the other hand, produces up to 77 t/h, with a circulating load reduction from 342% to 245%.

the cyclone diameter. The cylindrical section is the next basic part of the cyclone and is located between the feed chamber and the conical section. It is the same diameter as the feed chamber and its function is to lengthen the cyclone and increase the retention time. For the basic cyclone, its length should be 100% of the cyclone diameter.

The testing was conducted in a large copper ore mine which had a SAG mill in a closed circuit with the cyclone cluster. The trial tested one Cavex 2 650 in a sixplace cluster of existing Cavex cyclones and saw an improvement of up to % in circulating load and % in water bypass versus the original cluster, according to Weir Minerals.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.

The ball mill has higher circulation load, it generates only 30 35% of actual fines you require to be called as product. If your product size needed is 100% passing 45 micron, then the ball mill total discharge material will contain normally 30% of 45 micron. The rest is oversize which has to be ground again.

High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% 10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.
