1. PAINPOINT DRIVEN OPENING

Are your gold ore processing operations constrained by persistent bottlenecks and escalating costs? The primary crushing stage sets the tone for your entire recovery circuit, and suboptimal equipment here creates a cascade of downstream inefficiencies. Common challenges include:

Excessive Downtime: Frequent liner changes and unplanned maintenance in abrasive gold ores halt your milling circuit, costing thousands per hour in lost production.
Low Throughput Capacity: Inadequate feed opening or crushing force creates a bottleneck, preventing your SAG/ball mills from operating at designed capacity and limiting overall plant yield.
Poor Product Gradation: Inconsistent discharge sizing, with excessive fines or oversized material, reduces grinding circuit efficiency and can negatively impact downstream recovery processes like leaching or flotation.
High Operational Costs: Premature wear component failure, coupled with high energy consumption per ton crushed, directly erodes profit margins.
Material Handling Issues: Equipment not engineered for variable ore hardness (from soft oxidized ore to hard quartz vein material) leads to packing, bridging, and unreliable feed.

Is your current gold ore crushing equipment a reliable asset or a recurring liability? The right primary crusher is not an expense; it’s a strategic investment in plant stability and metallurgical performance.

2. PRODUCT OVERVIEW: HEAVYDUTY GOLD ORE CRUSHING EQUIPMENT

Our engineered solution for primary gold ore crushing equipment is built for maximum availability and throughput in demanding mineral processing environments. This machinery is designed to accept runofmine (ROM) gold ore directly from the mine haulage system.

Operational Workflow:
1. ROM ore is dumped into a rugged vibrating grizzly feeder, which scalps out fine material and directs oversize to the crusher.
2. Ore enters the crusher’s large feed opening and is subjected to highpressure compressive force between a fixed surface and a moving mantle/liner.
3. Crushed product discharges onto a main conveyor at a consistent, predetermined size set by the crusher’s closedside setting (CSS), ready for secondary crushing or direct feed to a grinding circuit.

Application Scope: Ideal for primary crushing of goldbearing ores including hard rock quartz veins, sulphide ores, and mixed oxidesulphide materials. Suitable for both stationary plant installations and modular/trackmounted setups for satellite deposits.

Limitations: Not designed as a standalone solution for final product sizing; requires integration with secondary crushing or grinding circuits for liberation. Maximum feed size is constrained by model selection.

3. CORE FEATURES

HighCapacity Hydraulic Adjustment | Technical Basis: Remote hydraulic adjustment of the crusher’s closedside setting (CSS) | Operational Benefit: Allows operators to change product size or clear a stall in minutes from a control room or local station, without manual intervention. | ROI Impact: Reduces downtime for routine adjustments by up to 80%, maximizing crusher utilization time.

Reinforced Chamber Design | Technical Basis: Optimized nip angle and increased throw for aggressive bite | Operational Benefit: Effectively draws in large, slabby feed material common in gold mining, reducing bridging and ensuring consistent throughput even with variable ore geometry. | ROI Impact: Improves overall plant feed stability; field data shows a 1525% reduction in bridgingrelated stoppages.

AbrasionResistant Alloy Liners | Technical Basis: Manganese steel alloys with specific workhardening properties | Operational Benefit: Liners develop a hard, wearresistant surface layer upon impact, prolonging service life in highly abrasive siliceous gold ores. | ROI Impact: Extends liner life cycles by 2040% over standard alloys, reducing part consumption costs and maintenance frequency.

Automated Overload Protection | Technical Basis: Hydropneumatic tramp release system with pressure sensing | Operational Benefit: Instantly discharges uncrushable material (e.g., tramp steel) by releasing the crushing chamber, preventing catastrophic damage to major components. | ROI Impact: Avoids weeks of downtime and sixfigure repair bills associated with major mechanical failure.

Direct Drive & High Inertia Kinematics | Technical Basis: Efficient direct coupling of motor to crusher drive shaft with heavyduty flywheels | Operational Benefit: Delivers constant power transmission and maintains momentum through load surges, ensuring consistent crushing action and particle size distribution. | ROI Impact: Industry testing demonstrates up to 10% lower energy consumption per ton of ore crushed compared to Vbelt driven systems under load.

Integrated Dust Suppression Manifold | Technical Basis: Sealed housing with strategically placed spray nozzles | Operational Benefit: Minimizes airborne silica dust at transfer points during dry crushing operations, critical for compliance with health and safety regulations (e.g., MSHA/OSHA). | ROI Impact: Reduces housekeeping labor costs and mitigates risk of regulatory penalties while protecting worker health.
