 · The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence, typical gold or copper ore requires between and kWh per ton of energy to reduce the particle size. Considering a typical mining operation processes 10,000 to 100,000 tons per day the energy expenditure in grinding is 50 percent of the cost of production of the metal. A research team ...

A ball mill is a type of grinder used to grind or blend 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 rotating about its axis. The axis of the ...

The Media Charge_Linear Wear_Ball Mills spreadsheet was designed to estimate the Linear Wear Rate Constants for a ball charge in a Conventional Ball Mill, as a function of its known dimensions and basic operating conditions. Also, the spreadsheet allows for the calculation of the typical Grinding Media Consumption Rate indiors; that is, gr/ton, gr/kWh, kg/hr or tons/month.
