1. The oil of hp series cone crusher quality is not good. The load-bearing capacity of the cracked oil film of lubricating oil is reduced, and the oil wedge cannot be formed, which causes the oil film to be broken and the HP cone crusher thrust bearing is directly contacted and burned.
2. Bad running-in of hp cone crusher. When replacing a new thrust bearing, the load should be gradually increased. If it is too large or too fast, the thrust bearing will be partially stressed and cause burnout. In severe cases, abnormal noise will occur in the crushing, and copper chips will appear in the oil return to make the thrust bearing fast Burned.
3. Overload of multi-cylinder cone crusher. Excessive iron or unsmooth discharge will cause the crushing force to increase, the thrust bearing assembly is overloaded, and the oil film ruptures and burns.
