Mill Speed Control Using Programmable Logic . The paper handle a few topics from cement industry, such are: critical speed, mill speed control. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls. Contact Supplier

Mar 16, 2010· Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers, allowing the use of different sizes of grinding media. Large balls are used at the inlet, to crush clinker nodules (which can be over 25 mm in diameter).

The mostused development was the Cormorant mill a horizontal mill with 24" conical grinding elements made of cementbonded rock emery (corundum), and driven at high speed. These, although expensive, avoided the dressing costs of conventional mills, and were used at .

Cement Mill. Cement clinker is usually ground using a cement ball mill. This is essentially a large rotating drum containing grinding media normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. Grinding systems are either 'open circuit' or 'closed ...
