1. PAINPOINT DRIVEN OPENING

Are your gold processing operations constrained by inconsistent throughput, excessive maintenance costs, and unpredictable recovery rates? The primary crushing stage sets the tone for your entire recovery circuit. Inefficient or unreliable premium gold ore crushing equipment directly impacts your bottom line through:
Throughput Bottlenecks: Underperforming crushers create a feed bottleneck for your SAG/Ball mills, leading to lost production hours.
Premature Wear Costs: Abrasive gold ores, particularly those with high quartz content, can degrade standard manganese steel at an accelerated rate, requiring frequent liner changes and associated downtime.
Unoptimized Liberation: Improperly sized feed material from the primary stage reduces grinding circuit efficiency and can hinder downstream gold liberation, negatively affecting overall recovery.
High Energy Intensity: Inefficient crushing technology consumes disproportionate power per ton of ore processed, a significant and growing operational cost.

Is your current setup delivering maximum yield per ton of ore? Are you managing crushing plant downtime more than you are optimizing it? The solution requires equipment engineered specifically for the density, abrasiveness, and variability of premium gold ores.

2. PRODUCT OVERVIEW

This product line encompasses heavyduty, highcapacity jaw crushers and gyratory crushers engineered as the primary workhorse for hard rock gold mining operations. Designed for the initial size reduction of runofmine (ROM) gold ore to a consistent, conveyable product for further processing.

Operational Workflow:
1. ROM ore (up to 1.5m lump size) is fed into the crusher’s robust receiving hopper.
2. Hydraulic adjustment systems allow operators to set the closedside setting (CSS) in minutes to achieve precise target product sizing (typically 150250mm).
3. The highinertia crushing action fractures the dense ore between a fixed surface and a reciprocating/moving surface.
4. Crushed material discharges onto a primary conveyor system for transport to the next stage of the mineral processing plant.

Application Scope: Ideal for stationary primary crushing stations in medium to largescale gold mining operations processing hard rock ores (e.g., quartz veins, sulphideassociated deposits). Not designed as a portable solution or for handling placer/alluvial gravels without significant prescreening.

6. APPLICATION SCENARIOS

West African Gold Mine – HighAbrasion Quartz Ore

Challenge: A Tier1 operator faced liner replacement every six weeks in their primary jaw crusher due to extremely abrasive ore. Downtime was cutting annual throughput targets.
Solution: Implementation of our premium gold ore jaw crusher with its modular liner system and optimized chamber geometry.
Results: Liner life extended to an average of fourteen weeks—a 133% improvement—and changeout time reduced by over forty percent. Annual plant availability increased by an estimated ~180 hours directly attributable to reduced crushing station maintenance.

North American Gold Processing Plant – Fluctuating Ore Hardness

Challenge: Variable ore competency from different pits caused frequent plugging events and product size fluctuations in their primary circuit, hampering SAG mill performance.
Solution: Installation of our gyratory crusher model featuring automated hydraulic setting adjustment.
Results: Operators now make realtime CSS adjustments based on loader operator feedback from the face or measured power draw. Product size consistency improved by over thirty percent as measured by standard deviation analysis on sample belts.
