of efficiency, in the same way that motor output power is related to motor input power by the motor efficiency. For a mill motor directly connected to the mill drive pinion, the following relationships apply. • Motor output power = input power x motor efficiency. • Effective mill grinding power = motor output power x CSE/100.

Air Classifying Mill is used for separating dry materials into different particle size fractions by their size, mass or shape also modify a particle size distribution. We have established a note worthy status among the Air Classifying Mill Manufacturers in India.

Motor power and media addition. The power drawn by the Vertimill motor is required to establish the grinding rate. Motor power should be measured using corrected power. As the grinding media wears fine enough to be carried out by the uprising velocity in the mill, the total media charge will diminish, and the power draw will decrease.

Gearless mill drives (GMDs) are the grinding solution of choice in challenging environments. By eliminating bolt-on mechanical components such as ring-gears, pinions, couplings and gearboxes, GMDs offer ore producers unrivalled availability, efficiency and durability, while reducing operating expenditure, according to GMD provider ABB.
