jaw crusher pex 350 wear plate

Addressing the High Cost of Jaw Crusher Wear Plate Failure

For plant managers and maintenance supervisors, the wear plates in your PEX 350 jaw crusher represent a critical, yet often problematic, component. The operational challenges are clear:

• Unscheduled Downtime: A failed wear plate halts your entire crushing circuit. With production rates of 50-100 tons per hour, every hour of downtime represents significant lost revenue.
• High Replacement Frequency: Standard manganese steel plates can require replacement every 4-6 weeks under high-abrasion conditions, leading to recurring parts costs and labor expenditure.
• Compromised Product Gradation: As wear plates degrade, the gap between the jaws fluctuates, resulting in inconsistent product size and potential non-compliance with product specifications.
• Secondary Damage Risk: A severely worn or broken jaw crusher PEX 350 wear plate can lead to damage to the crusher body and other internal components, escalating a simple parts replacement into a major repair.

Are you constantly balancing part costs against total operational uptime? Is the true cost of your wear plates measured in lost production hours?

Product Overview: High-Performance Wear Plate for Jaw Crusher PEX 350

This product is a precision-engineered replacement wear plate designed specifically for the PEX 350 model jaw crusher. It functions as a critical liner within the crushing chamber, directly absorbing impact and abrasion from feed material.

Operational Workflow:

1. Installation: The jaw crusher PEX 350 wear plate is fitted and secured to the movable jaw using recommended torque specifications.
2. Crushing Action: During operation, the plate protects the underlying jaw structure from direct contact with rock, ore, and aggregate.
3. Material Flow: Its profile guides crushed material downward through the chamber, promoting efficient throughput and reducing choke points.
4. Protection: The plate sacrificially wears, preserving the integrity and geometry of the crusher jaw itself.

Application Scope: Ideal for secondary crushing of granite, basalt, quartzite, iron ore, and recycled concrete in mining, construction, and aggregate production.

Limitations: Not designed for use with materials exceeding a specified hardness (e.g., >250 Mpa) without prior engineering consultation. Proper installation and correct crusher operation are required to achieve stated performance metrics.

Application Scenarios

#### Aggregate Production Plant | Challenge: A granite quarry was experiencing premature failure of its standard PEX 350 wear plates every 380 hours, causing unplanned downtime that disrupted load-out schedules. The cost per ton for wear parts was exceeding operational targets. Solution: Implementation of the high-performance jaw crusher PEX 350 wear plate with optimized alloy composition. Results: Wear plate life extended to an average of 550 hours per set. This translated to a reduction in annual change-outs from 5 to 3.5 cycles on average, cutting parts consumption by 30% and associated labor costs by an equivalent margin.

#### Gold Processing Circuit - Secondary Crushing | Challenge: In a milling circuit, inconsistent final product size from the secondary crusher was impacting grinding mill efficiency. Worn plates were changing the crusher's closed-side setting unpredictably. Solution: Fitting the precision-cast jaw crusher PEX 350 wear plate which maintained its profile longer due to superior work-hardening properties.| Results: Field data showed a more stable product gradation curve over the full life of the plates (+85% consistency). This led to a measured 5% improvement in downstream ball mill throughput due to more consistent feed size.
