Critical critical sppeed of ball mill in pisalivorno

The critical speed of ball mill in the pisalivorno hammer mill, the critical speed in theory refers to the speed when the centrifugal force is large enough to make a small particle adhere to the inside of the shell in a complete rotating process of the mill. The general range of mill speed is 65 to 80 of the critical speed type the size and application click for details.

Variables in ball mill operation paul o abbe174

The critical velocity CS is the centrifugal speed of the grinding medium against the cylinder wall. Obviously, milling will not occur when the medium is fixed on the cylinder, so the working speed will be a certain percentage of CS. The formula for the critical velocity is CS 12 GRR, where G is the gravity constant R.
