The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or
It is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter,,P M = Mill Constant * (Mill Diameter ) n where n = to It is evident that mill power is a function of the height at which the media is lifted and the density of the media,, PM = K #207; b LD where k is a proportionality constant.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
Analysis of ball mill grinding operation using mill power specific kinetic parameters. March 2014; Estimation of specific energy required for size reduction in ball mills by analysing Bond a
Mills usually operate in the range 65 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and autogenous mills
Estimate the power require to grind 100 tonne/h ore in a ball mill operating circuit with hydro cyclone at a. circulating load of 300 .Rod mill discharge has a P80 of 0 25 .Flotation feed size required correspond to 80 65 bond work index Wbm is determined to be / simplicity consider the product of all efficiency for power estimation to be equal to 1 and
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum chunk size, product size as P80 and maximum and finally the type of circuit open/closed

THE OPTIMAL BALL DIAMETER IN A MILL. The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. 3 The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding wet/dry.
Effective mill power draw Ball mill specific grinding rate Ball mill grinding efficiency The circuit output is defined as the production rate of fines by the circuit. It is calculated from three values: 1. The dry ore feed rate to the circuit (t/h). 2. The % fines in the circuit feed.
