The grinding roll system used within roller mills consists of grinding rolls, bearings, a bearing seat, inter-roll transmission mechanism and clutch rolling and distance adjustment mechanism.
In the actual work operations of the mill, the vibration amplitude of the roll produced by the defect of the roll grinding system and the impact of the load is called the stability of the roll grinding system. The grinding roll exerts a grinding effect on material, primarily through friction and extrusion.
The smooth operation of the grinding roll system is the key to ensure the grinding effect of the mill is carried out efficiently and properly. The poor stability of the grinding roll system will produce a periodic load/pressure on the grinding roll, increasing the friction force between the two rolls and the material, generating excessive friction heat and increasing energy consumption, resulting in wear and tear on the roll surface and reducing the grinding effect….Read more.
