Jaw crushers components
1. Frame
� Heavy-duty design
� Steel plate welded construction
� Welded by CO2 shield arc process
� Pressure relieved immediately after fabrication
2. Crushing Chamber
� Deep crushing chamber
� Sharp nip angle ensures high crushing capacity
3. Swing Jaw & Main Bearing Housings
� Allows removal from frame as an integral sub assembly
� Permits onsite substitution of a changeover unit in the event of bearing damage
� Swing Jaw is a robust steel casting with fully machined face to support swing jaw plate
4. Flywheel
� Balances inertia
� Promotes smooth operation
5. Eccentric Shaft
� Forged from hardened and tempered chrome molybdenum steel
� Particularly large diameters to suit heavy -duty application
6. Bearings
� Fag or SKF heavy -duty selfaligning double row bearings on swing jaw and main frame
� Bath oil lubrication ensures positive lubrication
� Bearing life in excess of 8 years under typical quarry applications
7. Hydraulic Cylinder
� Allows easy adjustment of discharge setting by moving toggle block to the desired setting
8. Shim
� Allows easy adjustment of closed side setting
9. Toggle Block
10. Tension Rod with Spring
11. Toggle Seat
� Allows smooth toggle plate stroke
12. Toggle Plates
� Designed to shear protecting crusher components if noncrushable object is introduced to crusher (i.e. Steel)
13. Check Plates
� Manganese steel castings allow easy replacement
14. Jaw Plates
� High manganese steel castings can be reversed allowing extended life
� Wedge lug system allows easy replacement
