The Heavy Duty Mining Jaw Crusher is a specialized variant of the PE series, re-engineered specifically for the extreme conditions of the mining sector. While standard crushers suffice for limestone, they often suffer in hard rock applications.
The Heavy Duty version addresses this with thicker side plates, a reinforced heavy-duty shaft, and oversized premium bearings. For the used equipment buyer, this model is a gem because:
Unstoppable Durability: Built with a higher safety factor, its structural lifespan far exceeds standard models.
Mining Grade: Designed to operate 24/7 in applications involving Iron Ore, Copper, and Gold.
Risk Mitigation: Minimizes the risk of frame cracking or bearing seizure in remote, high-stress environments.
If your project involves crushing rocks with a compressive strength exceeding 300 MPa, this is the only jaw crusher you should consider.
The Heavy Duty Mining Jaw Crusher is not just a standard machine with a new coat of paint. It is a purpose-built beast. In the mining industry, downtime is the enemy. A cracked frame or a seized bearing can cost millions in lost production. This crusher is designed with one goal: Unstoppable Reliability. It features a significantly higher weight-to-power ratio than standard aggregate crushers, indicating the sheer amount of steel used in its construction to absorb the punishment of crushing hard, abrasive ores.
Why Choose a Used Heavy Duty Model?
Over-Engineered for Longevity: These machines are built to last 20+ years. Buying a 5-year-old used unit means you are getting a machine that has barely broken in its structural life.
Cost vs. Performance: A new heavy-duty mining crusher is extremely expensive due to the cost of raw materials (thick steel). A used unit allows you to access “Mining Grade” equipment for the price of a standard “Quarry Grade” machine.
Risk Mitigation: For remote mines, the risk of equipment failure is high. The Heavy Duty model minimizes this risk with its robust design.
Key Technical Features
Reinforced Frame Assembly: The side plates and front wall are made from extra-thick steel plates. Critical stress points are reinforced with stiffeners. This rigidity prevents the frame from flexing under load, which is the primary cause of bearing failure.
Oversized Spherical Roller Bearings: This model uses bearings that are typically one or two sizes larger than those found in standard crushers of the same opening size. This allows for higher load capacity and cooler running temperatures.
Flywheel Energy: Heavier flywheels are used to store more inertia. This helps the crusher power through “hard spots” or oversized rocks without stalling the motor or causing current spikes.
Premium Wear Liners: Comes standard with Mn18Cr2 or Mn22Cr2 (Super High Manganese) jaw plates, which offer 20-30% longer wear life in abrasive applications compared to standard Mn13.
Working Principle
The fundamental principle remains the toggle mechanism, but the kinetics are tuned for Power rather than just Speed. The Heavy Duty crusher operates at a slightly lower RPM but with higher torque. This allows it to fracture extremely dense ore bodies. The deep crushing chamber maximizes the leverage exerted on the rock. The crushing angle is carefully calculated to grip round, slippery river stones or hard ore chunks without them popping back out of the chamber.
Applications and Material Suitability
This machine is strictly recommended for:
Metal Mining: Primary crushing of Magnetite, Hematite, Copper Porphyry, and Gold-bearing Quartz.
High Abrasiveness: Materials with high silica content that would destroy a standard crusher.
Extreme Environments: High altitude, extreme heat, or cold environments where steel brittleness can be an issue (the high-quality steel used here resists cold brittleness).
Refurbishment & Quality Check
Refurbishing a Heavy Duty Mining Jaw Crusher requires expertise. We perform Magnetic Particle Inspection (MPI) on the eccentric shaft to ensure no fatigue cracks exist. We check the bearing housing bores for ovality. We also inspect the heavy-duty flywheel hubs. Because these machines are used in critical applications, our testing standard is stricter. We ensure that the used unit you receive is ready to be dropped onto a concrete foundation and run continuously for years to come.
Common Customer Questions (FAQ)
Q: How can I tell the difference between a Standard PE and a Heavy Duty model?
A: Visually, the Heavy Duty model has thicker steel plates on the frame (we can measure this for you via video). It also uses larger bearing housings. We can provide the weight data—Heavy Duty models are significantly heavier than standard ones.
Q: Has the main shaft been inspected?
A: Yes, this is the most critical check. We perform Ultrasonic Flaw Detection (NDT) on the eccentric shaft to ensure there are no internal fatigue cracks. We guarantee the shaft is sound.
Q: Can this machine handle iron ore?
A: Yes, it is specifically designed for metal mines like iron, copper, and gold ore. It can withstand the high crushing resistance of these dense materials.
Q: What happens if I need to replace the bearings in the future?
A: These machines use standard international bearing sizes (SKF/TIMKEN/FAG equivalents). You can source them locally, or we can ship them to you. We ensure the bearing housings are within tolerance so new bearings fit perfectly.
