torque of cement mill

High/Low Torque Alarm on Vertical Roll Mill in Cement

One of the most common types of machinery in cement plants are vertical roll mills. The primary function of a vertical roll mill is to grind coarse rocks into fine material that can then be used to create cement. It was on one of these roll mills that the cement company was experiencing repeated gearbox failures (at least once annually).

Mill Bolting

Torque in basic terms is the force multiplied by the distance needed to overcome the friction created between the mating faces and parts of a fastener. If your contracting company uses torque and is very diligent in the application of their bolting techniques, you could only end up with a mill which has 50% of the bolts doing 100% of the work

Finding failure International Cement Review

During mill operation roller surfaces wear down, which results in a higher dynamic load, peaks which exceed the nominal torque and, in general, an instable mill operation and lower performance. In many instances, bearing failures at the rolls are caused by excessive dynamics in the grinding process.
