Jaw Crusher

Stone Jaw Crusher machine is kind of coarse crusher, mainly used in mining, building materials, infrastructure construction etc. The stone crusher machine can crush various materials with compressive strength not exceeding 320MPa.

  • Feed Size:100-1200mm
  • Motor Power:5.5-280KW
  • Processing capacity:5-700t/h
  • Applicable Materials: Quartz, granite, basalt, marble, calcite, dolomite, limestone, gypsum, pebble, bluestone, feldspar, glass, cement clinker, concrete, coal gangue, construction waste, gold ore, and other ores.

How to Select the Right Jaw Crusher? 

Selection hinges on material characteristics (max feed size, hardness, abrasiveness), required throughput (tph), desired output size (CSS), available motor power, and budget. Careful analysis ensures optimal, cost-effective performance.

How to Install and Operate Jaw Crushers for Efficiency?

Proper installation requires a robust, level foundation and precise alignment. Correct operation involves thorough pre-checks, empty start-up, controlled uniform feeding, avoiding overload/choking, and following the proper shutdown sequence.

Jaw Crusher Maintenance? How to Extend Jaw Plate Life?

Daily checks include fasteners, lubrication, and visual inspection of wear parts. Regular maintenance involves deeper inspections and component servicing. Extend jaw plate life significantly through proper material selection, uniform feeding, pre-screening, and strategically rotating or flipping the plates.

Common Jaw Crusher Faults? How to Troubleshoot?

Common faults include sudden stops (choking), reduced output, jaw plate issues, bearing overheating, excessive vibration, and toggle plate breakage. Troubleshooting involves systematically identifying causes like blockages, wear, loose parts, or improper settings.

Jaw Crushers vs. Cone/Impact Crushers: Pros & Cons?

Jaw crushers excel at primary crushing of large, hard materials due to their robustness. Cone crushers are better suited for secondary/tertiary hard rock crushing, offering higher reduction and better shape. Impact crushers produce excellent cubical product but wear much faster on hard, abrasive rock.
