The unsupported length is the dominate factor, because the critical speed is inversely proportional to the square of the unsupported length. Using a fixed unsupported screw length, the critical speed can be varied by the selection of the screw diameter, lead and end bearing supports. Critical Speed Formula N=C S x x 106 x NS = N x FS Where: N = Critical Speed (RPM) NS = Safe Drive Speed .

derivation of critical velocity of ball mill. derivation of critical velocity of ball mill 23 Jan 2011, The grinding in ball mill is therefore caused due to:, charge will centrifuge is known as the critical speed of the mill and is given by formula:
Critical Speed: The "Critical Speed" for a grinding mill is defined as the The basic formula for this is the Bond formula: Hence a rod mill generally precedes a ball mill in a grinding circuit especially where a fine size product is required.
