How to Calculate Grinding Mill Operating Efficiency In grinding, operating Efficiency compares the operating index of a comminution machine to the Bond index from bench scale crushing and grindability tests or/and pilot plant tests. Economic Efficiency is comparing the income from production to the planned income from production.

The first method used to determine 100% power efficiency is grinding the ore in a 450 mm Aerofall Mill. This mill is operated with a standard ball charge for all ores producing normally a minus 14 mesh product. The 450 mm mill is a replica of the standard Aerofall Mill and is complete with an air classifying system and an automatic feeding system.

Calculate Efficiency Grinding Grinding energy u of 35 wsmm3 the grinding wheel rotates at 3600 rpm has a diameter d of 150 mm thickness b of 25 mm and c 5 grains per mm2 the motor has a power of 2 kw the work piece moves v at 15 mmin the chip thickness ratio r is 10 determine the grinding force and force per grain determine the.

May 15, 2017· Before getting into the four categories that influence grinding efficiency, it's important to know how the grinding process works. When you're using a grinding machine, three interactions are happening at the same time: cutting, plowing and sliding. What you're creating determines the primary interaction occurring.
