In this article the effect ofgrinding media size distributionandfeed material particle size distribution(PSD) on the product fineness requirements were investigated. A model free approach called the Attainable Region method was then applied in order to optimize theproduct size finenessin terms of thefeed sizeandball mix.

Thesize distributionof theballsin themill chargeappears to have no significant effect upon thesize distributionof the product, nor upon therate of grinding, provided that thesize distributionof theballsis not too unreasonably chosen.

Silica ore was used as the test material. Particle Size Distribution of Grinding Mill Products For example, reduction to one-half of the original particle size requires about4-3 kg cm pergm by impact as compared to18.5 kg-cmby ball mill; that is, the energy requirements are less than 25 percent as much for impact crushing as for ball milling.

Allow me to compare:Ball millscan be of the overflow or of the grate discharge type. Overflow dischargemillsare used when a product with high specific surface is wanted, without any respect to theparticle size distributioncurve.Overflow dischargemillsgive a final product in an open circuit.

A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of80% passing ¼ inch(6350 microns). The required product size distribution is to be80% passing 100 mesh (149 microns).

The grinding results show that changes in feed size, agitator speed, and grinding media size mainly affect the particle breakage rate. The test data also show that a finer product size is obtained...

Key properties ofgrindingmedia include composition, hardness,sizeand density. Some common types include alumina, stainless steel, yttria stabilized zirconia and sand.Ball millingwill result in aballcurveparticle size distributionwith one or more peaks. Screening may be required to remove over or undersized materials.
