Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is m diameter and m long with a corresponding motor power of 22 MW not least because the specific power consumption of vertical mills is about 30% less than that of ball mills
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 A simplified picture of the mill load is shown in Figure Ad this can be used to establish the essential

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
the mill has increased to 160 t/h with an specific power consumption of Kwh/ t OPC at blaine of 2700 cm 2 /gm. The percentage benefits for the above two parameters are depicted below:

Power Consumption Of Ball Mill czeu. Scaleup of power consumption in agitated ball mills . Abstract. Previous investigations have shown that the specific energy input is the overall parameter of influence on product size during communition in agitated ball mills, from laboratory up to industrial scale.
grinding media (steel balls) on power requirements and energy consumption of a ball mill. With constant mass of the steel balls (20, 30 and 40 kg), the agitator shaft speed was increased from 10 to of the maximum speed, which corresponds to a speed of 50 rpm. The power consumption (W) was recorded upon which milling energy consumption
Charge behaviour and power consumption in ball mills: sensitivity to mill operating conditions, liner geometry and charge composition. Author study the effects of changes in mill operating parameters and particle properties on the charge shape and power draw of a 5m ball mill. Specifically, changes in charge fill level, lifter shape
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

Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
