SAG mill balls experience both significant abrasive and impact wear due to their large (75 – 100 mm) diameters. Ball mill balls experience a greater number of impacts, but at lower magnitude than SAG mill balls, due to the smaller ball size, and smaller mill diameter. Feeds are typically highly abrasive,

chemical composition is relatively wide, 2 – 4% C and 1,5 to ca. 30% Cr in whole range it is white cast iron. Besides chromium it usually include other alloy additions from which the most important are: Mo to 3% and Ni to 5%. Moreover its cast iron may include not large amount: Cu, V, Ti, W, B and N. Taking into account different combination of chemical composition its initial microstructure ...

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

Grinding balls. This type of the grinding media made of steel and cast iron. Manufacturing methods – helical rolling of round billet, molding, stamping. Recently, manufacturers of stamped balls losing their relevance in the market, because this method is quite energy intensive, which leads to higher costs of the finished products.

The properties of a casting are - apart from alloy composition and heat treatment - strongly influenced by the casting process and part design. Mechanical properties will vary with the local freezing rate from location to location within a single casting. Exact mechanical performance data can thus be difficult to obtain in forms other than minimum and typical values and FE analysis is ...

Let us look back at the optimal ball charge in a mill. The necessary number of balls having the definite diameter N b in a mill should be proportional to grain number N having the definite diameters which they can grind: N b ~ N. (7) The number of grains of the material with determined diameters depends on the grain size distribution.
