GMSG GUIDELINE: DETERMINING THE BOND EFFICIENCY … - power consumption calculation for closed circuit ball mill

The power drawn by the mill is determined from the ball contact forces acting on the mill lifters and liners. At any wall element the contact normal and tangential force is resolved into the x and y components, and the distance from the mill centre determined .A torque arm calculation is performed, and the torque integrated over all contacts and all timesteps.A power analyser was utilized to measure mill power. Increase in mill speed and ball filling leads to a remarkable increase in the amount of the power. Preliminary results show that there is a definite trend between the power and the slurry filling U. Mill power draw is maximum at slurry concentration 60–70% and slurry filling 0.84.

The power consumption calculated for the rod and ball compartments were 401 and 753 kW, respectively. These values indicate a power consumption ratio of 34.8 % for the rod compartment and 65.2 % for the ball compartment. The Bond formula (Equation 2) was used to calculate the required power for both compartments (rodThe maximum power draw in ball mill is when ball bed is 35-40 % by volume in whole empty mill volume. Considering that ball bed has a porosity of 40 %, the actual ball volume is …

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 calculated from known tables 'the old fashion way'.CALCULATION OF THE POWER DRAW OF DRY . Equation 1 is multiplied by the factor of 1.08. A multi-compartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw. The total power is the sum of the power . More
