>HOME>Of Torque Of Cement Mill

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).

The mill manufacturer specifies a load which is designed to be the optimum load applied to the bolts to hold the mill together for its entire life, which can be in excess of 20 years, some mill manufacturers specify an elongation, unfortunately they usually specify a torque figure which should in a best

Inching drives in a cement plant have two possible applications that support the production of product. The first of which is the heart of any • Full load running torque required at the kiln or mill shell at inching operating speed. Typically this is set at 120% of main drive operating torque. • The desired output speed at the
