Get PriceThe objective of this dissertation was to investigate how media shape affects grinding. Ball size distribution inside an industrial mill was analysed in terms of shapes and sizes. Load behaviour, mill power and breakage as affected by media shapes were studied in a pilot laboratory mill. An inductive proximity probe, light.

Get Priceworks and full size plant observations showed that ball diameter, as an operating variables, can affect grinding efficiency at a given output fineness in ball milling. It is however known that there is a specific ball size which maximises the breakage rate of a given size fraction of a material (Austin et al, 1984; Gupta et al, 1985).

Get PriceIntroduction. Barite is being produced in various region of Turkey, mainly in Adana, Konya, and Isparta that is widely used as oil drilling, painting, paper and plastic sector, etc. In these industries, grinding of barite mineral is needed (Deniz,. 2012). It is well known that it is very difficult to reach ultraf- ine sizes by dry grinding in...
