Jaw crushers components

1. Frame
§ Heavy-duty design
§ Steel plate welded construction
§ Welded by CO2 shield arc process
§ Stress relieved 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
