The grinding rollers are raised hydraulically from the grinding table prior to commencing grinding. This is realised by reversing the oil pressure exerted on the spring assembly cylinders. The grinding mill can therefore be started in an empty or full state with a low starting torque (approx. 40% of the nominal torque).

Creep feed grinding is a slow, one-pass operation that makes a deep cut of up to one inch in steel materials at low table speeds between 0.5 and 1 ipm. It is not suitable for conventional grinding machines, but for those which are compatible with it, it offers high productivity and cost effectiveness.

Load capacity is the maximum allowable force that can be applied to a stage in a specified direction while meeting stage specifications. This maximum force includes static (mass × gravity) and dynamic forces (mass × acceleration). Dynamic forces must include any external forces, such as vibrations, acting upon the stage.
