Pitman is one of main components of jaw crusher and also the complicated structure part,It is widely used in mining, chemical, cement, steel and other industries.The reasonable structure of the movable jaw is the sufficient condition to ensure the superior performance of the crusher, and its strength and stiffness affect the performance of the equipment directly.On the basis of summing up casting experience,we go on technology improvement and innovation.
1.Special heat treatment technology is used for movable jaw so that casting structure is optimized, hardness is increased.Casting performance is also improved.
2.Moveable jaw is made of high strength steel. In order to ensure the components stability in the long-running and increase the service life,we make casting optimized according to the jaw crusher’s operating characteristics.
3.Large manufacturing capacity within a short period.
4.Standard:ASTM, JIS, GOST, DIN, BS, WCB, etc.
2. Pattern check
5. Risers cut
6. Sand clean
7. Heat treatment
8.Peel and grind
9. Weld and polish
10. Blast and paint
11. Rough machine
12. Fine machine
13. Inspect and pack
