Ball Mills

13/02/2017An increase in the mill speed will give a directly proportional increase in mill power but there seems to be a square proportional increase in the wear. Rod mills generally operate within the range of 60—75 % of critical speed in order to avoid excessive wear and tangled rods. Ball and pebble mills are usually operated at 70—85 % of critical speed. For dry grinding the

Shakers, Rockers, and Rotators

The motor speed may be adjustable, to offer a gentle mixing motion through to a more vigorous high-speed mixing action. Shakers typically provide either a reciprocal to-and-fro, orbital or wrist motion, rockers a wave or see-saw motion, and rotators rotate their samples either in a horizontal or vertical plane, with adjustable models offering tilts at all angles in between.

Base Stabilization Best Practices

The depth at which you are stabilizing will determine the size of roller required. Typically, base stabilization ranges from 6 to 14 inches. "Our stabilizers will mix up to 24 inches deep, but you can only process how deep you can compact," White said. "Most contractors' rollers can compact around 10 to 12 inches.".
