Grinding Media Wear Rate Calculation in Ball Mill - 911 MetallurgistApr 29, 2017 . in which R is the rate of wear of any ball of weight W; K is a constant and depends upon the operating conditions of the mill and the resistance of the material .. Since the large ball is just as likely to strike the small pieces of ore and the small ball is just as likely to strike the large pieces of ore as the reverse,.piece weight of grinding media,How Can I calculate new ball size and weight desing for ball mill .4.See the availability of roller press in comparision with the mill. 3.If the performance of roller press will be too good the u can run the mill only 24-26% loading with a very good out put and low specific energy. 4.Tonnage of grinding media u can calculate on the basis of dia.length and the filling degree.
For various diameters of steel balls in chromium and stainless steel, weight per 1000 pieces.
More balls with small size results in fine powder. As a thumb rule powder to be milled should be taken as 25% of total ball weight. If the quantity of charge is very less then milling balls will start to collide with each other and no milling will take place. Ball size depends on initial size of charge and ranges from 10mm-150mm.

inc. V = the volume of charge, cm. V = grinding media or volume, inc. M. = weight of the charge, cm. M. = weight grinding media, ( cm inc M. M. ≈. ), ρ = the density of the material of grinding media, cm ρ = bulk density of grinding media. Bulk density of grinding media can be determined (if ρ and ε are known), with the relation.
Mar 4, 2013 . The nonporous CoorsTek high-density media are a tougher charge with longer life. With this media, CoorsTek helps customers to improve productivity, enhance product purity, and reduce operating costs. CoorsTek offers two materials for general purpose grinding: AD-90 (90% AI2O3) with superior density.
A grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the make-up ball sizes in tumbling ball mills. .. The breakage distribution is often used in the cumulative form, Bij = ∑ k = nibkj which is the cumulative weight fraction of material broken from size interval j which.
