1. PAINPOINT DRIVEN OPENING

Are you facing persistent bottlenecks in your primary crushing circuit that limit overall plant throughput? The challenges of processing hard, abrasive gold ore are quantifiable: excessive wear on manganese steel components leads to unplanned downtime for liner changes, directly costing in lost production hours. Inconsistent feed size from blasting operations can cause bridging and choking, requiring hazardous manual intervention and stalling your milling process. Furthermore, inefficient initial size reduction forces secondary and tertiary crushers to work harder, accelerating their wear and increasing your total cost of ownership per ton.

How do you achieve consistent, highvolume primary crushing while controlling maintenance costs and protecting downstream equipment? The solution begins with selecting the right primary gold ore crushing equipment.

2. PRODUCT OVERVIEW

This product line focuses on heavyduty jaw crushers engineered specifically for the primary crushing stage of gold ore processing. These machines are designed to accept runofmine (ROM) feed directly from the mine haul trucks.

Operational Workflow:
1. Feed Intake: ROM gold ore (typically up to 1meter top size) is dumped into the vibrating grizzly feeder (VGF), which scalps off fine material.
2. Primary Reduction: Oversize material is directed into the crusher's fixed and moving jaw dies, where immense mechanical pressure fractures the rock.
3. Discharge: Crushed product discharges at a preset closedside setting (CSS), typically between 150mm to 200mm, ready for conveyor transport to secondary crushing or stockpiling.

Application Scope & Limitations:
Scope: Ideal for hard rock gold deposits (quartz veins, sulphide ores), suitable for both stationary plants and semimobile setups. Handles high compressive strength materials effectively.
Limitations: Not designed for wet, sticky ores without proper feeder design; requires a prepared foundation; initial capital investment is significant compared to smaller units.

6. APPLICATION SCENARIOS

Hard Rock Underground Mine RampUp

Challenge A new underground portal required a primary crusher to handle lumpy quartzite ore with a UCS of over 250 MPa. The tight space demanded a robust unit with minimal external infrastructure that could operate reliably with infrequent but intensive maintenance windows.
Solution Installation of a singletoggle jaw crusher with hydraulic CSS adjustment and an integrated motor base directly under the ore pass.
Results Achieved design capacity of 800 TPH within one week of commissioning. The quickadjust system allows the night shift to alter product size for blending needs without delaying dayshift haulage.

Expanding OpenPit Processing Plant

Challenge An existing plant’s secondary circuit was being starved due to insufficient primary crushing capacity after mine expansion. Downtime for liner changes on the old unit was causing major bottlenecks.
Solution Replacement with a larger doubletoggle style jaw crusher known for lower wear costs on highly abrasive sulphide ore.
Results Plant throughput increased by 22%. Liner life improved by an average of 40%, aligning changeouts with quarterly planned maintenance stops instead of unplanned interruptions.
