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.
Working principle. Ball mill grinding machine is a kind of horizontal drum-type grinding mill with external gear and double bins. Materials goes evenly through quill shaft in feeding device into the first bin, which has ladder lining or ripple lining with steel balls in different specifications.Steel balls are taken to a certain height by centrifugal force from drum rotation and then fall.
