Installation of Fixed Umbrella Board of Cone Crusher | Life Insurance

During the operation of the cone crusher, the umbrella plate is most easily to be worn. The ore directly contacts the umbrella plate. The service life of the umbrella plate is related to the hardness of the ore and the grinding member. The umbrella board is generally made of high manganese steel and the service life is from 3 to 6 months. When quality of the manganese steel is too poor, such as the improper heat treatment, the umbrella board will be damaged within dozens of days, even within a few days. The fixed umbrella board is hanged on the steel hook of the adjustment ring by the ?U? shaped bolt. The zinc alloy layer should be casted between the fixed umbrella board and the adjustment ring to ensure that they are closely integrated.
When you replace the fixed umbrella broad on the adjustment ring, you should clear and clean the dirt on the adjustment ring and the surface of the fixed umbrella surface, which is very advantageous to ensure the quality of the cast zinc alloy. When the adjustment ring falls on the fixed umbrella, you should check the centre position according to the processing position of the upper parts of umbrella board or lower part of umbrella plate. After the confirmation, you can appropriately tighten the platen of the ?U? bolt on the upper part of the adjusting ring. For gap exists in the joint part between the adjustment ring and the fixed ring, you should carefully fill other suitable materials to prevent the outflowing of zinc alloy in the casting process. If conditions allow, you should dry the contact surface of the zinc alloy, which is very beneficial to the pouring quality of the zinc alloy. After cooling the cast zinc alloy, you should clear the zinc alloy on the edge of the upper portion of the plate and retighten the nut of the ?U? shaped screw platen. Ensuring the tensioned state between the fixed umbrella plate and the adjustment ring is very important.
