1. PAINPOINT DRIVEN OPENING

Are your gold processing operations constrained by inconsistent feed size, excessive liner wear costs, or unplanned downtime in the primary crushing stage? Inefficient initial size reduction directly impacts downstream milling efficiency, leading to higher energy consumption per ton and lost recovery opportunities. Consider these common challenges:
High Abrasion Costs: The extreme hardness and abrasive nature of goldquartz ores rapidly degrade crusher liners, resulting in frequent maintenance shutdowns and high consumable parts expenditure.
Throughput Bottlenecks: Inadequate primary crushing capacity creates a bottleneck, limiting mill feed and capping overall plant production potential.
Unpredictable Downtime: Component failures in critical crusher assemblies lead to unscheduled stoppages, costing thousands per hour in lost processing time.
Poor Particle Size Distribution: Inconsistent output product size increases load on secondary crushers and grinding circuits, reducing their operational efficiency and increasing power costs.

Is your primary crushing circuit a reliable asset or a recurring cost center? The solution begins with specifying OEMengineered China Gold Ore Crushing Equipment designed for the specific demands of auriferous ore.

2. PRODUCT OVERVIEW

This product line encompasses heavyduty primary jaw crushers and gyratory crushers engineered as the first stage in hard rock gold ore comminution. These machines are built to accept runofmine (ROM) gold ore with maximum feed sizes up to 1200mm and reduce it to a manageable product for secondary crushing.

Operational Workflow:
1. ROM gold ore is fed via dump truck or loader into the crusher’s vibrating grizzly feeder (VGF).
2. The VGF removes fines and directs oversize material into the crushing chamber.
3. A robust, oscillating jaw or mantle exerts immense compressive force, fracturing the ore against a stationary surface.
4. Crushed material discharges onto the main plant conveyor for transport to the next processing stage.
5. Hydraulic adjustment systems allow operators to modify the closedside setting (CSS) to finetune product size without downtime.

Application Scope & Limitations:
Scope: Ideal for primary crushing of hard and abrasive gold ores (quartz, sulphides), mine waste rock, and construction aggregates in largescale mining and fixedplant operations.
Limitations: Not designed for wet, sticky ores without prior scalping; requires a stable concrete foundation and significant installation planning.

3. CORE FEATURES

HeavyDuty Manganese Steel Liners | Technical Basis: Workhardening Hadfield steel composition | Operational Benefit: Liners develop a hardened surface layer during operation, extending service life in highly abrasive conditions by up to 40% compared to standard alloys. | ROI Impact: Reduces liner replacement frequency and associated labor costs, directly lowering costperton for consumables.

Hydraulic Adjustment & Clearing | Technical Basis: Integrated hydraulic cylinders for CSS adjustment and chamber clearing. | Operational Benefit: Enables quick setting changes for product size control and safe, rapid clearing of tramp metal or blockages without manual intervention. | ROI Impact: Minimizes downtime for routine adjustments and clears stalls in minutes versus hours, maximizing plant availability.

Spherical Roller Bearings & Labyrinth Seals | Technical Basis: Oversized bearings with multistage sealing systems. | Operational Benefit: Handles high radial and axial loads with superior heat dissipation; seals effectively exclude dust and contaminants from bearing housing. | ROI Impact: Extends bearing service life significantly, preventing catastrophic bearing failure—a leading cause of extended unplanned downtime.

Optimized Crushing Chamber Geometry | Technical Basis: Computermodeled nip angle and stroke profile based on gold ore characteristics. | Operational Benefit: Promotes interparticle crushing for improved reduction ratios and generates a more consistent product curve with fewer slabby or flaky pieces. | ROI Impact: Improves overall circuit efficiency by providing optimal feed for secondary/tertiary stages, reducing cycling load.

Modular Frame Design | Technical Basis: Fabricated steel sections bolted together under stressfree conditions. | Operational Benefit: Simplifies transportation to remote sites, allows for easier replacement of individual frame sections if damaged, and facilitates future relocation. | ROI Impact: Lowers logistical costs for greenfield projects and reduces longterm maintenance complexity.

PLCBased Automation Interface | Technical Basis: Crusher metrics integrated with plant Distributed Control System (DCS). | Operational Benefit: Allows remote monitoring of power draw, CSS, pressure, temperature; enables automated load regulation and fault diagnostics. | ROI Impact: Enables proactive maintenance scheduling based on actual operating data, optimizing personnel deployment.

6. APPLICATION SCENARIOS

West African Hard Rock Gold Mine | Challenge: Extremely abrasive quartzite ore was causing jaw crusher liner changes every 6 weeks at significant cost and downtime (~24 hours per change). Secondary circuit was often starved due to primary throughput limitations.| Solution: Replacement with a JC160 HeavyDuty Jaw Crusher featuring optimized chamber geometry and proprietary liner alloy.| Results: Liner life extended to an average of 9 weeks (+50%). Throughput increased by ~18% due to higher reduction ratio in single pass. Annual savings exceeded $200k in parts/labor/downtime avoidance.

Chinese Polymetallic Sulphide Operation | Challenge: Frequent blockages from occasional tramp metal delayed feed by several hours per incident; manual clearing posed safety risks.| Solution: Installation of a GC426 Gyratory Crusher equipped with full hydraulic adjustment and automatic clearing cycle.| Results: Blockage clearance time reduced from an average of 3 hours to under 20 minutes via remote operation from the control room. Improved site safety protocol compliance.
