Overview
Jaw crushers are heavy-duty primary crushers that use a fixed and a movable jaw to crush large rocks and ores into smaller, manageable sizes. Common in mining, quarrying and demolition, they handle oversized feed and deliver high reduction ratios and reliable throughput. Buyers should consider feed opening, capacity, wear parts availability, and compatibility with their tracked or stationary crushing plants.
FAQ
What should I inspect when buying a used jaw crusher?
Check jaw plates and liners for wear, frame and cheek plate condition, bearings, toggles, drive components and hydraulic systems. Verify service history, hours, and any repairs. Confirm feed opening size and capacity meet your needs.
How is a jaw crusher shipped and what should I prepare?
Jaw crushers are heavy; plan for low-loader or flatbed transport. Use certified lifting points, consider partial disassembly (flywheel, conveyors) to lower height/weight, and secure all loose parts. Confirm permits and route limits for oversized loads.
What maintenance keeps a jaw crusher reliable?
Regularly inspect and replace jaw plates, grease bearings per schedule, check toggle and tensioning systems, monitor drive belts and pulleys, and keep dust seals intact. Maintain lubrication, tighten fasteners, and follow the manufacturer’s inspection intervals.
