Problems based on Size reduction 1. A certain crusher accepts a feed material having a feed size of 19 mm and gives a product of 5 mm. The power required to crush 15 tones per hr is kw. What will be power consumption if the capacity is reduced to 12 tones per hr with same feed and product size? The mechanical efficiency remains unchanged. Assume that the Rittingers law is applicable ...

Highenergy mill (HEM) has a wide application in material preparation, activation and synthesis. In the present study, fly ash was selected to be milled by HEM under the speed of 700 rpm and the balltopowder ratio of 10:1 by weight, but varied periods of milling time. The changes in physical and morphology properties of the milled fly ash were determined using BET analysis and scanning ...

The acceleration factor of the ball or rod mass is a function of the peripheral speed of the mill. Thus. n = c9np/√D, the above equation becomes P = f1 (D²)·f5 (πD c9 np/√D) = cs np As a first approximation, the capacity, T, of a mill may be considered as a function of the force acting inside the mill.
