In general, therefore, the required mill power is calculated using the following equation where n is the number of efficiency factors, EFi, used and fo is the feed rate of new ore to the mill. The power calculated from equation 2 can be looked up in published tables (Rowland and Kjos, 1978) and the correct mill size and type can be selected.

experience or laboratory tests before mill size can be determined. The required mill net power P kW ( = ton/hX kWh/ton) is obtained from. P = const. x c x q x nc x Li x Di2.5; where an approximate figure for the constant is 3.5 for rod mills, 4.0 for overflow ball or pebble mills and 4.5 for grate discharge ball or pebble mills.

Ball mills designed for long life and minimum maintenance overflow ball mill sizes range from 5 ft. x 8 ft. with 75 HP to 30' x 41' . and as much as 30,000 HP. Larger ball mills are available with dual pinion or ring motor drives. Our mills incorporate many of the qualities which have made the Marcy name famous since 1913.

Limestone is fed by gravimetric feeder from limestone silo to wet ball mill. The limestone slurry from wet ball mill shall be discharged to mill overflow tank. Grinding water for the limestone ball mill shall be ratio controlled by the signal of gravimetric feeder to maintain specified solid content at outlet of mill .

The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to draw this power is .

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. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential ...

Abstract: In determining the proper mill size required to meet a targeted production rate, many factors are evaluated including: length to diameter (L/D) ratio, individual compartment lengths, rotational velocity, liner type, ball gradation and percent filling degree. This paper examines the effects of changing mill filling degree with respect to specific power consumption (kWh/ton) and ...

DOVE Ball Mills are size reduction machines, designed for grinding applications, where fine material is required. Applicable for the grinding applications within the following branches of industries: – Mining – Construction – Waste Processing – Food Processing – Chemical – Pyrotechnics – Ceramics and etc.

the mill power and the efficiency of the mill operation (Van Nierop and Moys, 2001). If a SAG mill has been designed with a conventional power or specific energy model which do not con-sider the projected feed size distribution it is likely that this mill will reach the expected power .

Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications).
