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).
