ISOCertified Gold Ore Crushing Equipment: Engineered for Maximum Yield and Minimum Downtime

1. PainPoint Driven Opening: The High Cost of Inefficient Comminution

Processing gold ore presents a unique set of profitability challenges directly tied to your crushing circuit’s performance. Inconsistent feed size, abrasive sulfide ores, and the relentless demand for throughput create significant operational hurdles. Are you facing:
Recovery Loss: Poorly sized crusher product leading to gold particle lockup in downstream processes, directly reducing overall plant yield.
Unscheduled Stoppages: Frequent mechanical failures in critical components due to extreme abrasion and shock loads, resulting in costly, unpredictable downtime.
High Operating Costs: Excessive energy consumption per ton of ore processed and rapidly escalating wear part expenses that erode profit margins.
Maintenance Complexity: Lengthy, laborintensive liner changes and component servicing that keep your equipment—and skilled personnel—out of operation for days.

The core question for plant managers is this: how can you achieve consistent, speccompliant product size while controlling the total cost of ownership and maximizing gold liberation? The answer lies in precisionengineered, ISOcertified crushing equipment designed specifically for the rigors of gold ore processing.

2. Product Overview: Primary & Secondary Hard Rock Gold Ore Crushers

This product line encompasses robust, stationary jaw crushers and cone crushers engineered for the primary and secondary crushing stages of hard rock gold ores (e.g., quartz veins, sulfidebearing deposits). The operational workflow is optimized for continuous mineral processing plants:

1. Primary Reduction: ROM (RunofMine) ore is fed into a heavyduty jaw crusher, reducing large material to a manageable size (typically <200mm).
2. Secondary Crushing: The jaw crusher discharge is conveyed to a highperformance cone crusher for further reduction to a target size optimal for grinding mill feed (typically <20mm).
3. Size Control & Recirculation: Crusher product is screened; oversize material is recirculated back to the cone crusher in a closed circuit to ensure consistent final product specification.

Application Scope: Ideal for medium to hightonnage fixedplant operations processing abrasive and hard gold ores (Unconfined Compressive Strength up to 300 MPa). Limitations: Not designed for wet, sticky ores without prior drying/scalping, or as standalone units for allinone crushing without appropriate screening and conveying systems.

3. Core Features: EngineeringDriven Performance

Patented Liner Geometry | Technical Basis: Optimized crushing chamber kinematics and nip angle | Operational Benefit: Produces a more cubical product with fewer fines and slabby material, improving downstream grinding efficiency and gold liberation. | ROI Impact: Field data shows up to an 8% increase in grinding circuit throughput due to improved feed characteristics.

MultiLayer Chromium Alloy Mantle & Concaves | Technical Basis: Microalloyed steel with directional hardening for maximum abrasion resistance. | Operational Benefit: Extends wear life by 3050% compared to standard manganese steel in highly abrasive gold ores. | ROI Impact: Reduces wear part inventory costs and frequency of changeouts, lowering costperton significantly.

HydroPneumatic Tramp Release & Clearing | Technical Basis: Automated system using hydraulic accumulators and nitrogen charge. | Operational Benefit: Protects the crusher from uncrushable material damage; clears a stalled cavity in under 60 seconds without manual intervention. | ROI Impact: Prevents catastrophic damage to main shaft and frame; reduces risk of hourslong downtime events associated with tramp iron incidents.

Centralized Grease Lubrication with Flow Monitoring | Technical Basis: Automated, programmable lubrication system with sensors at each bearing point. | Operational Benefit: Ensures optimal bearing lubrication under all loads; provides early warning of blockages or failures before they cause damage. | ROI Impact: Extends major bearing service life by up to 40%, avoiding unplanned teardowns and associated labor costs.

Dynamic Adjustment Under Load (ASRi®type System) | Technical Basis: Continuous, sensorbased control of the crusher’s closedside setting (CSS). | Operational Benefit: Maintains consistent product gradation despite varying feed conditions or liner wear, operating fully under load. | ROI Impact: Delivers a stable product size critical for recovery optimization; increases total throughput by maintaining peak cavity performance.

Modular Frame Design with Maintenance Rails | Technical Basis: Fabricated steel sections bolted with precision alignment dowels; integrated overhead crane rails. | Operational Benefit: Enables faster assembly onsite and allows for swift removal/replacement of major components like the eccentric assembly during scheduled maintenance. | ROI Impact: Reduces planned maintenance downtime by up to 50%, increasing annual operating hours.
