Gold Ore Crushing Equipment Contract Manufacturer Specification
Targeted Gold Ore Crushing Solutions for HighTonnage, HighAbrasion Operations
Are your gold processing plant’s profitability margins being eroded by crushing circuit bottlenecks? Operational challenges in primary and secondary crushing directly impact recovery rates and bottomline results. Common pain points include:
Excessive Downtime for Maintenance: Frequent liner changes and unplanned repairs on abrasive gold ores (particularly quartzrich deposits) halt your entire processing line, costing thousands per hour in lost production.
Inconsistent Feed Size Reduction: Inefficient crushing leads to poor liberation of gold particles, creating downstream inefficiencies in grinding and leaching circuits, ultimately reducing overall recovery.
High Operational Costs: Skyrocketing energy consumption per ton of ore processed, coupled with the high cost and short lifecycle of wear parts in highly abrasive environments.
Material Handling Issues: Ineffective crushing can produce excessive fines prematurely or fail to break down claybound conglomerates, causing clogging and handling challenges.
Is your current equipment delivering the required availability and costperton metrics necessary for today's volatile gold markets? The solution lies in specifying a robust, engineeredtotask gold ore crushing system.
Product Overview: HeavyDuty Gold Ore Crushing Equipment
Our contract manufacturing service delivers customengineered primary and secondary crushing solutions specifically built for the demands of gold ore processing. This equipment is designed to handle highabrasion feeds, from hardrock quartz veins to complex sulphide ores.
Operational Workflow:
1. Primary Size Reduction: Large runofmine (ROM) ore is fed into a rugged jaw crusher or gyratory crusher for initial breaking.
2. Secondary Crushing & Screening: Material is conveyed to a cone crusher for further reduction to a predetermined size, then screened to ensure optimal feed for the grinding mill.
3. Recirculation & Final Product: Oversize material is recirculated back into the crusher circuit, while correctly sized product is sent to the next stage of your beneficiation process.
Application Scope: Ideal for medium to largescale gold mining operations requiring throughput from 150 to over 2,500 tonnes per hour. Suitable for both stationary plant installations and modular plant designs.
Limitations: Not designed for alluvial or placer deposit processing without significant prescreening; optimal performance requires welldefined feed size and moisture content parameters.

Application Scenarios
HardRock Underground Mine Expansion
Challenge: An existing operation scaling up throughput faced bottlenecks with an aging secondary crusher unable to handle increased tonnage of hard quartz ore without frequent mechanical issues.
Solution: Implementation of a customconfigured heavyduty cone crusher with automated setting regulation as the core of an expanded secondary crushing circuit.
Results: Achieved sustained throughput of 600 tph at a consistent 25mm product size. Mechanical availability reached 95.5% over the first year, supporting the plant’s expansion goals without additional downtime.
Refractory Sulphide Ore Processing Plant
Challenge: A new greenfield project processing complex sulphide gold ore required extreme reliability due to remote location logistics making spare parts delivery slow and costly.
Solution: Specification of a complete primary jaw crusher and secondary cone crusher package with enhanced wear protection packages on all critical components.
Results: The robust design exceeded liner life projections by 30%, allowing maintenance scheduling aligned with planned quarterly shutdowns. This eliminated two unplanned liner change events in Year One, saving an estimated three weeks of lost production time.
