Hammer stone production line, back-breaking life extension method:
In order to improve back-breaking hammer wear resistance, welding a thin layer of hard alloy in its surface coated.
Manganese steel system back-breaking hammer wear, available manganese steel electrode surfacing methods to patch it. Chromium, high chromium material hammerhead is not easy to repair. The process of impact crusher hammer top of the surfacing can be introduced to the surfacing metal composition of 1.2 ~ 1.5mm ranging from axis of granular columns stand Ortega solid carbide based alloy for a dedicated high-chromium cast iron.
End disk and intermediate disk crusher rotor Ministry to improve the utilization of the back-breaking hammer, and relative to extend the life of the hammer. PC800mm × 800mm back-breaking, for example, in the end of the disc and intermediate disc with a drill the six 40mm diameter pin pitting, uniform in diameter 450mm circumference, staggered 30 ° center of a circle with the original pin hole angle arrangement. Continue to work in the original position after the pros and cons of two alternate use can not be a full set of hammer pin and gap sets removed, and 6 with drill diameter 40mm shaft hole assembly to ensure that the balance of the rotor.
