Product Introduction
Primary crushing for large feed material.
A jaw crusher uses a fixed jaw and a moving jaw to compress large feed into a smaller size. It is normally installed after controlled feeding and before secondary crushing, screening or grinding.
Common applications include quarry stone, granite, basalt, limestone and ore preparation. The required opening and model depend on the real feed size and output duty.
Main Features
What this machine does in practical operation.
- 01Compression crushing
The moving jaw compresses material against the fixed jaw for primary size reduction.
- 02Large-feed duty
The documented model range covers different feed openings for quarry and mining applications.
- 03Adjustable discharge range
The discharge opening is selected within the documented range for the required downstream size.
- 04Accessible crushing chamber
Jaw plates and the chamber can be inspected as part of routine wear management.
- 05Line integration
The machine can work with feeders, conveyors, secondary crushers and screens.

Technical Details
Working Principle
How a jaw crusher reduces large feed material.
A motor drives the eccentric shaft so the movable jaw approaches and moves away from the fixed jaw. Material is compressed in the chamber and leaves through the lower opening after it becomes small enough.
Process stepWhat happens inside the machineWhat the buyer should check
FeedingMaterial enters the chamber between the fixed jaw and movable jaw.Maximum feed size and whether a feeder controls the material.
CrushingThe movable jaw repeatedly compresses material against the fixed jaw.Material hardness, abrasiveness, moisture and unwanted metal.
DischargingCrushed material leaves through the opening at the bottom of the chamber.Required output size and whether secondary crushing or screening is needed.

Download Technical SheetMaintenance and Installation
Use an inspection plan based on operating hours and real wear.
The checklist below is a planning framework. Exact intervals and procedures must follow the supplied manual, site safety rules, material abrasiveness and inspection findings.
Daily / Each Shift
- Check guards, fasteners and visible damage.
- Listen for abnormal noise or vibration.
- Observe feed stability and discharge clearance.
- Check lubrication condition as instructed.
Weekly
- Inspect belts, drive parts and accessible bolts.
- Check jaw-plate wear and chamber condition.
- Review blockage or overload records.
- Clean accumulated material safely.
Monthly
- Record wear measurements and compare trends.
- Inspect support, alignment and safety devices.
- Review lubrication records and leakage.
- Plan required wear-part replacement.
Annual / Major Shutdown
- Complete a qualified inspection of major components.
- Check bearings, drive, support and chamber parts.
- Replace confirmed worn components.
- Review spare-parts stock and maintenance records.
Safety: Stop and isolate the power before clearing blockage, adjusting or replacing parts. Installation, lifting and electrical work require qualified personnel and the confirmed machine drawing.
Installation preparation
Confirm foundation or support dimensions, anchor positions, maintenance clearance, feed arrangement and discharge connection before the machine arrives.
Wear parts
Confirm the actual machine model, jaw-plate profile, part markings, photos and dimensions before ordering jaw plates, toggle parts, belts or related components. Planning your first spare-parts order? See the jaw crusher spare-parts checklist.
Commissioning
Check alignment, fasteners, guards and rotation direction, then complete the no-load and controlled-load checks required by the supplied instructions.
Common Operating Problems
Start troubleshooting from the operating condition.
These are general checking directions. Stop safely and contact qualified technical personnel when the cause is uncertain.
Observed problemPossible checking directionPractical response
Unstable outputUneven feed, changing feed size, discharge restriction or worn jaw plates.Stabilize feeding and inspect the chamber, setting and wear condition.
Frequent blockageOversized feed, sticky material, uncontrolled feeding or insufficient discharge clearance.Stop safely, clear the chamber and correct the feed or discharge condition.
Abnormal vibration or noiseLoose fasteners, drive alignment, worn parts or foundation condition.Stop for inspection instead of continuing under abnormal operation.
Fast wearAbrasive material, uneven feeding, unsuitable operation or delayed replacement.Review material, feeding practice and wear-part inspection records.
Buyer FAQ
Questions to resolve before selecting a jaw crusher.
What materials are suitable for a jaw crusher?
Jaw crushers are commonly used for quarry stone, granite, basalt, limestone, river stone, gold ore, copper ore and other hard or medium-hard materials. Final suitability should be checked by real material condition.
Who commonly uses a jaw crusher?
Common users include quarry operators, mining users, aggregate plants, contractors, EPC companies and local equipment dealers.
Where is a jaw crusher used in a production line?
A jaw crusher is typically placed after a feeder and before a vibrating screen, secondary crusher or grinding equipment.
Choosing a jaw crusher for a quarry? Check feed opening, capacity and discharge duty → For output planning, read the jaw crusher capacity guide. For machine quotation factors, see the jaw crusher price guide.
