Grinding Mills: Ball Mill & Rod Mill Design & Parts

Grinding Mill RPM – Rotating Speed Grinding Mill speed is one of the factors affecting the character of the cascading charge. As shown in the illustrations, the lower the percentage of critical speed, the smoother the flow of balls from top of charge to bottom. Higher percentage of critical speed is used for impact grinding of large feed.

Reliable, easy maintenance rotor weighfeeders | FL

A load cell weighs the content in the rotor gravimetrically, providing the bulk material mass in kilograms and this is stored together with the relative rotor wheel position. The rotor speed is controlled accordingly – more material, less speed; less material, more speed. The rotor weighfeeder then discharges the material at the outlet.
