JMC Heavy Duty jaw crusher
JMC Heavy Duty Jaw Crusher – Industrial-Grade Crushing for Demanding Applications
The JMC Heavy Duty Jaw Crusher is purpose-built for primary stage crushing of the toughest materials—ranging from ROM (Run of Mine) minerals and rock to heavy construction and demolition rubble. This machine is engineered around a compression-based crushing principle, where a robust pitman mechanism and elliptical motion ensure high-impact, continuous crushing force.
🔧 Key Features:
- Rugged Construction: Built with modular, non-welded frames to deliver maximum fatigue strength and prolonged durability in all directions.
- Heavy-Duty Jaw Box: Designed with one fixed and one moving cast manganese liner, engineered for effective crushing under heavy loads.
- Precision Pitman Assembly: The pitman is made from cast steel, connected to a hardened forged crankshaft, producing elliptical motion for optimal crushability.
- Large Equal-Sized Bearings: All four main bearings are equal in diameter and oversized to maximise performance and longevity.
- Advanced Bearing Housings: Single-piece, cast steel bearing housings provide high load capacity and straightforward maintenance.
- Easy Maintenance: Ring feeders for flywheel locking, machined and bolted jaw stopper plates, and accessible housing designs simplify service work.
- Modular Design: Economical to recondition after years of operation—ideal for long-term deployment and plant integration.
- Dynamically Balanced Flywheels: Cast iron flywheels improve operational balance and extend bearing life.
📊 Application Areas:
- Quarrying and mining
- Large-scale construction and demolition recycling
- Processing of granite, steel slag, and other abrasive materials
- High-volume material reduction
