Jaw Breaker

Product Introduction

When the primary jaw crusher goes down, the entire crushing circuit stops — screens, cones, conveyors, stockpiling. The real problem is not the machine. It is the lead time you cannot control.

You contact the supplier. The answer is "45 days, maybe 60." You cannot confirm a delivery date, so you cannot confirm a restart date. You either hold extra capital in spare machines and oversized stock, or you wait and lose production every day.

For a mid-size quarry, each day of primary crushing downtime means lost output, delayed shipments, and penalty clauses. The cost of waiting is often higher than the cost of the machine.

Our Solution: Lead Time You Can Actually Plan Around

ZHUOYUE reduces uncertainty by confirming technical requirements before production starts — not during it. Crusher model, feed material, output, discharge range, motor, structure, wear parts, and inspection requirements are locked in a documented technical baseline. Production then runs without interruption.

What this delivers:

• Fewer delays: Specifications are confirmed before machining, preventing rework and repeated drawing revisions.

• Clear lead times: Standard and customized models follow separate, published schedules.

• Lower inventory costs: Long-term buyers can reserve raw material in advance, so production does not restart from zero each order.

• Better planning: Progress updates and pre-shipment inspection records let your team prepare foundations, lifting, and installation labor in advance.

This does not eliminate lead time. It makes lead time predictable — so you can plan restart dates, control stock, and stop losing production to uncertainty.

Product Features

1. Frame and cavity design
Frame manufactured from confirmed steel grade with welded or cast construction. Welds inspected according to the confirmed welding procedure. Cavity geometry confirmed according to feed gradation, moisture, and required throughput. Designed to support stable feed flow under specified operating conditions.

2. Wear parts matched to the application
Jaw plates and side guard plates available in Mn13, Mn18, Mn22, and other wear-resistant grades. Material grade, hardness, and heat treatment confirmed according to feed abrasiveness and required service interval. Hardness and impact toughness verified against the confirmed specification.

3. Discharge adjustment
Hydraulic, gasket, or combined adjustment according to model. Adjustment range confirmed according to the required product size. Operating procedure provided in the operation manual.

4. Toggle plate overload protection
Toggle plate designed as a sacrificial component. If uncrushable material enters the cavity, the toggle plate is intended to fail before major structural damage occurs. Replacement toggle plates available as spare parts.

5. Maintenance access and spare parts supply
Lubrication points and maintenance access arranged according to the model. Recommended lubrication interval and jaw plate replacement procedure provided in the operation manual. Wear parts and common spare parts can be supplied under a long-term framework agreement.

Applications

• Mining and ore processing: primary crushing of iron ore, copper ore, gold ore, and other hard ores

• Quarry and aggregate production: granite, basalt, limestone, river stone, and similar materials

• Construction waste recycling: concrete rubble and mixed demolition material

• Infrastructure projects: aggregate supply for highways, railways, and commercial concrete

Final configuration depends on feed material, required output, discharge size, and site conditions. Please confirm with our technical team before ordering.

Quality Control

Each jaw crusher is inspected against the approved technical requirements and applicable standards before shipment.

1. Incoming Material and Component Inspection

• Material grade: Verified by spectrochemical analysis or certificate review. Chemical composition according to ASTM E415 or GB/T 223 where required.

• Castings and forgings: Visual inspection for cracks, shrinkage, porosity, and surface defects. Acceptance criteria per approved drawing and applicable casting standard.

• Forging inspection: UT or MT arranged according to material specification and customer requirements.

2. Manufacturing Inspection

• Critical dimensions: Frame, bearing seats, and mounting interfaces measured against approved drawing. General tolerances per ISO 2768-1 where individual tolerances are not specified.

• Welds: Inspected per confirmed welding procedure. UT, MT, or PT applied as required. Inspection ratio and acceptance criteria per weld grade and customer requirements.

• Hardness: Brinell per ISO 6506-1 or ASTM E10; Rockwell per ISO 6508-1 or ASTM E18 where specified.

• Mechanical properties: Tensile strength, yield strength, and elongation per ISO 6892-1 where required.

• Impact toughness: Charpy per ISO 148-1 where specified.

• Microstructure and case depth: Per confirmed material specification.

3. Pre-Shipment Inspection

• No-load running test: Duration, speed, current, vibration, and noise recorded per confirmed test procedure.

• Dynamic balance: Per confirmed balance grade and test procedure where applicable.

• Discharge adjustment: Opening range verified against confirmed specification.

• Final check: Visual and dimensional inspection against approved drawing before shipment.

4. Documentation and Traceability

Available documents include material certificate, dimensional inspection report, heat treatment record, weld inspection report, no-load test record, and dynamic balance report where applicable.

Batch traceability covers raw material batch, production batch, heat treatment batch, and inspection record.

Third-party inspection by SGS, Bureau Veritas, or a customer-appointed inspector can be arranged on request. Scope, standards, and fees confirmed before inspection.

FAQ
