Ball Mills an overview ScienceDirect Topics

The ball mill is a cylindrical drum (or cylindrical conical) turning around its horizontal axis. It is partially filled with grinding bodies: cast iron or steel balls, or even flint (silica) or porcelain bearings. Spaces between balls or bearings are occupied by the load to be milled.

AMIT 135: Lesson 7 Ball Mills & Circuits Mining Mill

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

Scale up of lifters in ball mills ScienceDirect

01/10/1985· INTRODUCTION Although many factors influence grinding rate and energy consumption in ball mill grinding, liner design {lifter design) is one of the most important parameters. Mill liners {lifters) are the agents to transmit energy and impart motion to the grinding balls, which in turn comminute ore particles( Dunn, 1976). Rose and Sullivan {1958) stated that the optimum lifter size, for
