Costs – Media that may be 2–3 times more expensive may last considerably longer, and therefore, be well worth the extra cost over the long run. The type of mill also can affect the selection of grinding media. Ball Mills use very large media while Attritors employ media ranging in size from 1/8" to 1".

Ball mill media ball loading and ball size and matching

The grinding gap between the ball and the ball is dense with the decrease of the ball diameter. Therefore, the ball with larger mass and smaller diameter should be used. For grinding media. The size of the ball depends mainly on the particle size of the material to be milled, and secondarily the diameter and speed of the mill can be

ENERGY SAVINGS AND TECHNOLOGY COMPARISON USING

The use of small grinding media (5 12 mm), called Millpebs, in regrind mills proved that fi ner grinding can be achieved at lower energy consumption. In ball mills, energy savings vary from 10 per cent to 40 per cent compared to 25 mm media. A regrind ball mill with a mix of small grinding media

Grinding media density. The range of specific gravity for commercially available grinding media runs from sp.gr. 1.0 for plastics to sp.gr. 15 for tungsten carbide. It makes sense that you wouldn''t select a very light grinding bead for a highly viscous system or a very dense grinding bead for a lowsolids aqueous suspension.

Cement mill Wikipedia

The mill is usually divided into at least two chambers (although this depends upon feed input size mills including a roller press are mostly singlechambered), allowing the use of different sizes of grinding media. Large balls are used at the inlet, to crush clinker nodules (which can be over 25 mm in diameter).

Attritor, Grinding Media, Dry Grinding, Wet Grinding

The Attritor is often referred to as a agitated ball mill. GRINDING MEDIA: Of these, only size and density control its ability to disperse, the other factors being secondary. In other words, for a given size and given density, the material of which the bead is made makes no difference in its ability to disperse.
