  • Formula For Grinding Mill Power Draw

    The fraction of mill volume occupied by rocks, grinding media and slurry in grinding mills are dominant factors influencing AG and SAG mill power draw and grinding rate. Hence accurate mill filling measurements are needed for modelling mills. To that end, it is usually necessary to enter the confined space of a grinding mill, a task that involves a degree of safety risk and a potentially.Fig. 1 Hammer Mill. 2.2 Attrition Mills. Attrition mills use the hammermill principle to a certain extent i.e., shattering by impact. However, they also impart a shearing and cutting action. Grinding is done between two discs equipped with replaceable wearing surfaces. One or both of these discs is rotated if both, they rotate in opposite.

    Grinding capacity is calculated according to the factory’s capacity. Crushing roller mill rolls should be up to approximately 40 percent of the total roller mill length, Reduction (liso) roller mill rolls are up to 60 percent of the total roller mill lenght. The average lenght of the roller mill is based on the account of12mm 100kg 24 hours.

    Power draw for each mill is in the region of 5200kW with a feed rate of about 1700 tph (consuming about 3 kWh t of energy), milling from a feed size of nominally 80 minus 150mm to a grind P. 80. in the region of 340 microns. The ore at IOC is ideal for AG milling comprising a small amount of hard . component that acts as grinding media.

    Oct 06, 2009 This means that the power draw decreases by the third power of the impeller outer diameter reduction. So a 10 diameter reduction (19 head reduction) would result in a 27 reduction in the power draw, plus any reduction from the lower percent flow rate. This is the same impact as pump speed, which can, however, be varied during operation.
