Heavy Duty Jaw Crusher PE-600x900 Rock Stone Machine for Quarry Primary Crushing

The Heavy Duty Jaw Crusher PE-600x900 is engineered as the workhorse of primary crushing, turning large run-of-mine rock into uniformly sized material for downstream processing. Its robust welded frame, deep symmetrical crushing cavity and high-manganese jaw plates allow it to handle hard, abrasive materials with a compressive strength of up to 320 MPa. From iron ore and granite to basalt and construction demolition waste, this machine delivers a steady, predictable reduction ratio that keeps the whole crushing plant running at capacity. Operators value its simple mechanical structure, which translates into fewer wear parts, shorter downtime and a lower cost per ton.

• Deep Crushing Cavity: A non-clogging, symmetrical cavity with no dead zone increases the feeding capacity and improves the material flow, so throughput stays high even with sticky or slabby feed.
• Gasket Discharge Adjustment: The discharge opening is set through a shim gasket system that is reliable and convenient, offering a wide adjustment range for flexible product sizing.
• Reliable Lubrication: A safe, well-protected grease lubrication system reduces friction on the eccentric shaft and bearings, extending service intervals and simplifying maintenance.
• Simple Reliable Structure: Few moving parts and a bolt-together frame mean low operating cost, easy inspection and fast replacement of jaw plates and toggle plates.
• Wide Adjustment Range: The large discharge setting range lets one machine produce a variety of product sizes, reducing the need for secondary equipment in many circuits.
• High Manganese Wear Parts: Reversible jaw dies made from high-manganese steel deliver long wear life and can be rotated for maximum utilization of the wear metal.

This primary jaw crusher is the first stage in quarry and mining production lines, feeding impact or cone crushers for further reduction. It is widely applied to granite, basalt, river stone, limestone, iron ore, gold ore and construction waste recycling. Typical installations include aggregate plants, cement raw material preparation, metallurgical slag processing and sand and gravel yards where a dependable, high-throughput first-stage crusher is required.

Each unit is shipped in a heavy-duty steel frame or plywood export case with the flywheel, motor and jaw dies secured for ocean transport. Critical machined surfaces are protected with anti-rust oil. A full set of operation and maintenance manuals, a spare set of toggle plates and fasteners are included. All machines pass a full running test before dispatch, and our engineers provide remote commissioning support and a twelve-month quality warranty, with wear parts available year-round.
