ادامه مطلبThe grinding roller bearing is the key and fragile part in of vertical grinding mill. There are two forms of lubrication for roller bearing: Immersion lubrication and forced circulation lubrication. At present, thin oil circulating lubrication is widely used in roller lubrication of vertical grinding mill.
ادامه مطلبSecond, the grinding roller lubrication system does not return oil. When the roller is working, the bearing will generate some heat and it is in a high temperature environment. Therefore, it is generally lubricated by thin oil circulation, so that excess heat can be taken away to ensure that the bearing is in the normal temperature range.
ادامه مطلبThe grinding roller installed on the grinding plate of the mill seals the air to form a space. In this way, a ring-shaped seal cleaning system can be formed. It not only ensures that the powder will not enter the roller bearing, but also prevents the powder from damaging the oil seal. All links are closely linked and indispensable.
