The vertical pre-grinding mill is primarily composed of the electric motor, speed reducer, grinding wheel, grinding roller, hydraulic system, and the lubrication system. The feeding material is firstly delivered to the middle of the grinding wheel.
Operating pressure of hydraulic system is low, can reduce the leakage failure and the mill vibration, is good for operation and management. 7. The centralized circulating oil lubrication is applied to the grinding roller bearings, which ensures the bearing operate at constant temperature and with pure oil, so that longer service life is achieved.
A hydraulic system is a drive technology where a fluid is used to move the energy from e.g. an electric motor to an actuator, such as a hydraulic cylinder. Hydraulic systems are mainly used where a high power density is needed or load requirements chance rapidly. This is especially the case in all kinds of vertical roller mill.
But for vertical roller mills, the growth rate of that of material will gradually decrease. From this point of view, roller press is superior to vertical mill. In roller press, the contact area between the two rollers and the material is small; the material is ground by only passing through the roller press once due to the large grinding ratio.
