Vertical roller mill is the wear of the bearing, the whole set of equipment is the most demanding bearing, so the protection of bearings must be done in place, so as to ensure the smooth production.

1. How to protect the bearing of vertical roller mill?
Vertical roller mill is the wear of the bearing, the whole set of equipment is the most demanding
bearing, so the protection of bearings must be done in place, so as to ensure the smooth
production.
First of all know bearing vertical roller mill so mounted to each worker: the old method of vertical
milling machine hollow shaft of rolling bearing is suitable for processing into the hollow shaft
bearing inner diameter, outer bearing heating device, bearing, bearing inner rings with a top
cover, the top cover on the inlet and outlet spiral tube bolt fixed in the hollow shaft, press. In the
grinding process, the inlet and outlet spiral tube, fixed bolts often loose, causing the top sleeve
and the hollow shaft displacement, the dust from the gap between the top set of hollow shaft
and the bearing box into the grease, dirty, leading to poor lubrication, bearing damage
phenomenon have occurred from time to time.
The use of thin oil lubrication in the bearing vertical milling machine, can make the friction
coefficient of the bearing is reduced to the minimum, better energy saving effect, and the use of
thin oil lubrication, the normal operation of the bearing temperature, dry oil lubrication bearing
temperature is much lower, prolonging the service life of the bearings; bearing seat is provided
with the oil level to observe the oil standard, the operator can see the oil level height, can
replenish the oil, prevent oil lubrication, the bearing damage accident; vertical bearing mill base
oil chamber oil content, reduce the external diameter of the rolling bearing can be installed in the
installation of charging and discharging device (to ensure sufficient strength and torque), the
hollow shaft with a flange and the inlet and outlet spiral tube connecting end connected with the
feed screw, the cylinder flange. By the end of the hollow shaft tapering, a pressing bearing ring
flange, to prevent the bearing axial channeling out.
