Energy efficiency IsaMill Advantages Isamill
The use of tower mills as an energy efficient alternative to secondary and regrind ball milling became a common inclusion in the latter part of the previous century. Traditionally the higher energy efficiency was attributed to the difference between attrition grinding in tower mills and impact grinding in ball milling.

Addition of pebbles to a ball mill to improve grinding
The idea of using a mixture of balls and pebbles, at a mill speed suitable for ball milling, was revisited in this investigation, using a normal spectrum of pebble sizes (1975 mm). Batch tests in a pilot scale mill (0.57 m diameter) were used to compare ball milling to various ball/pebble mixtures. The mill power was measured online by
The energy efficiency of ball milling in comminution
Earlier work by Fuerstenau and Kapur on the comminution of quartz in a single particle roll mill and in a dry ball mill showed the energy efficiency of ball mill comminution to be 22%. Thus, as a mechanical device for producing fine particles, the ball mill is reasonably efficient energetically.

Ball Mill Operating Speed Mechanical Operations Solved
At what speed will the mill have to be run if the 100 mm balls are replaced by 50 mm balls, all the other conditions remaining the same? Calculations The critical speed of ball mill is given by, where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm.
