Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1. For fine regrinding in open circuit, the ...

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing . continuous operation similarly it is suitable for open as well as closed circuit grinding and is applicable Ball Mill. We bring forth a highly advanced Ball Mill specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design bearing ...

The only manipulated variable available in the closed milling circuit (ball mill 2) is the cyclone dilution water flow rate. Attempts to use this for density control were not successful. Because of the high magnetite concentration of the ore it was found that the actual density exceeded the required density, causing the density control loop to become unstable. If the operator did not intervene ...

AG Mill + Ball Mill + Crusher (ABC Circuit) This can be used to correct a too coarse product from the primary mill. Mostly operated wet, but also dry possible. AG Mill + Pebble Mill. Two stage AG-grinding with the primary mill in open circuit and the secondary pebble mill in closed circuit. The pebbles screened out from the primary mill or recirculated to the primary mill based on size ...

The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed ...

Each milling circuit is unique, and as such the goals and most optimal control strategy might differ for individual cases. Process IQ is an expert in implementing control systems for SAG and Ball milling circuits, making use of advanced stabilisation and optimisation strategies developed by Mintek.
