Design, material selection:
1. When the design, hubei and hubei crushing plate should be of teeth the tooth valley. So, the broken besides squeezing effects for the material, when there are bending effect, the material is easy to broken. In order to prolong the service life of crushing plate, small and medium-sized crusher crushing plate into the shape of a symmetrical design, when the lower wear adjustable head after use; Large jaw crusher crushing plate pieces that are designed to be symmetrical each other, so that the wear after crushing plate switch can be used.
2. The crushing plate materials can choose white cast iron. White cast iron is larger hardness, good wear resistance, easy source, low price; The disadvantage is that brittle and easily broken, short service life. In order to improve the service life of the crushing plate, material better by more than 12% of manganese content in manganese steel, commonly used is ZGMn13. The disadvantage of manganese steel is more expensive, but from the overall consideration, service life and cost ZGMn13 than white cast iron long service life, low cost.
Assembly:
Assembly, crushing plate must be firmly attached to the jaw plate, between the two should be flat, between crushing plate and jaw plate with soft metal gasket (such as lead, zinc, etc.), and bolts. Crusher, crushing plate should not have loose phenomenon, otherwise easy to break or wear crushing plate, reduce the service life of the broken plate. Therefore, the assembly must be installed crushing plate, so as to prolong the service life of the broken plate.
In use process improvement in order to prolong the life of the broken plate:
In the process of production, the broken plate and material directly, crushing force is very big, especially when broken larger material hardness, lead to install bolts crushing plate vibration, loose nut, crushing plate wear and great noise, serious when broken plate fall off or broken equipment downtime, affect the normal production. Encounter this kind of situation, only tighten the bolt, nut is not complete before starting the solution to the problem, according to the actual situation of site specific issues specific analysis, to find a way to take a practical approach to solve the problem.
In short, in use process can according to the specific circumstances to find a way to solve specific problems, to prevent crushing plate is loose, wear, broken, etc., so as to prolong the service life of crushing plate, reduce costs, improve work efficiency.
