Jaw Crusher Structure, Jaw Crusher Design, Jaw Crusher Diagram
SBM mining machinery has long history in design jaw crusher. With many years of research base on a large of staffs, our company has developed a strong technical team and provides good after-sale service for jaw crusher. Below introduce our factory jaw crusher structure and characteristics.
SBM jaw crusher design with many advantages:
• Energy saving
• Low noise, little dust
• Simple structure, working steady, operation cost is low
• Big crushing ratio, product particle size uniform
• Deeply crush cavity and no dead zone that improve the production capacity
• Large scale adjustable range that meet different user requirements
• Gasket type adjusting devices of jaw crusher discharging mouth that's reliable, convenient, wide adjustment and increased the equipment of flexible
Main parts of jaw crusher structure refer to the diagram
1. Jaw Crusher 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. Jaw Crusher Flywheel
• Balances inertia
• Promotes smooth operation
5. Eccentric Shaft aligning double row bearings
• Forged from hardened and tempered chrome molybdenum steel
• Particularly large diameters to suit heavy -duty application
6. Jaw Crusher Bearings
• Fag or SKF heavy-duty self aligning double row bearings on swing jaw and main frame
• Bath oil lubrication ensures positive lubrication
• Bearing life in excess of 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 non-crushable object is introduced to crusher
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
