Ball Size as Initial Charge. Commercial ball sizes 10 – 150 mm; Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., dâ†"V = 0.40 ...

Impact and attrition size-reduction methods include air classifying mills, pin mills, hammer mills and jet mills. Shear, impact and compression methods are used in media or ball mills. The five types of milling technologies discussed in this article cover more than 90 percent of size-reduction applications in major chemical, food ...

Size Reduction Goals. To help make sense out of the dizzying array of milling options, start at the end by first considering — not the milling machine — but the end product. The most important step in selecting the right size reduction equipment is to establish the target size reduction goal for the end product at the outset.

Hammer mill is a size reduction machine that consists of high speed swinging hammers mounted on rotor which impacts on the materials fed into it and get them disintegrated to finer particles such ...

Dec 23, 2013· In ball mill, size reduction is done by both impact and attrition of particles. Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a self-grinding mill which is used in breakage of larger rocks.

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio "length to diameter" and this ratio most frequently varies from 0.5 to 3.5. The
