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 ...

Grinding control strategy on the conventional milling ...

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 ...
