Milling usually means reducing material to sizes in the low micron or even nano-size range. Crushing mostly is done dry while attrition milling may be done wet or dry [1]. In this article we'll discuss attrition …
The Bureau's Pittsburgh (Pa.) Coal Research Center (now with the U.S. Department of Energy) for a number of years investigated comminution of anthracite to determine the finest anthracite particle that …
The working principle of a ball mill is based on the impact and attrition between the balls and the grinding media. As the mill rotates, the grinding media (usually steel or ceramic balls) are lifted to a certain height and then allowed to fall freely, causing the materials to be reduced in size by the impact and abrasive forces generated ...

Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …
