### 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).
