Tracking the mill performance showed that the mill power consumption decreased from to kWh/t (a nearly 30% reduction), P 80 of the mill product decreased from 611 to 355 m, and the mill fresh feed flow rate increased from 511 to 521 t/h by decreasing the feed ore hardness from 112 min to 58 min based on SAG power index (SPI).
average specific power consumption (power at mill pinion shaft) for the AG tests was kWh/mt, compared with kWh/mt for the SAG tests. The specific power consumption values for both types of primary grinding agreed very well with the results of the simulation work performed by .

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
Jan 01, 2016#0183;#32;For autogenous mills, like the dry Aerofall mills, MacPherson and Turner established that the power consumption was a function of mill diameter and length. For dry commercial AG mills they derived the power as () P M = L D c where c = bulk density of the mill charge (rock plus balls and water) (t/m 3 )
What is the power consumption per hour of the rod mill. 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

Tracking the mill performance showed that the mill power consumption decreased from to kWh/t (a nearly 30% reduction), P 80 of the mill product decreased from 611 to 355 m, and the mill fresh feed flow rate increased from 511 to 521 t/h by decreasing the feed ore hardness from 112 min to 58 min based on SAG power index (SPI). Finally, a model was developed for the prediction of mill power
ball mill power consumption Such mills are usually called pebble mills, but the working principle is the same as for ball mills As the power input is approximately directly proportional to the volume weight of the grinding media, the power input for pebble mills is correspondingly smaller than for a ball mill, The specific power consumption is therefore less than for.
Scaleup criterion is the net specific power consumption, the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids. For the full scale mill, specific power is multiplied by the feed rate to get the net mill power.
Highefficiency autogenous mill can realize the second and third stage crushing and screening, and part or all crushing and grinding of rod mill or ball mill. Low power consumption, no dust pollution, less auxiliary equipment, easy production automation, and stable particle size.
The electric power consumption by this process run on ore mining and processing enterprises is variously estimated as a value from 5 to 20% of overall world electric power.
