1. PAINPOINT DRIVEN OPENING

Are your gold processing operations constrained by inefficient primary crushing? The bottleneck at this initial stage ripples through your entire circuit, directly impacting profitability. Common challenges include:

Excessive Downtime for Maintenance: Frequent liner changes and unplanned repairs on abrasive gold ore halt your milling circuit, costing thousands per hour in lost production.
Inconsistent Feed Size for SAG/Ball Mills: Poorly controlled crusher product size leads to poor grinding circuit performance, higher energy consumption per ton, and reduced overall recovery rates.
High Operational Costs: Premature wear on crusher components due to high silica content and abrasiveness drives up your cost per ton in replacement parts and labor.
Capacity Limitations: An undersized or outdated primary crusher prevents you from scaling throughput to capitalize on highergrade ore bodies or optimized mine plans.
Safety Risks with Manual Adjustment: Traditional crushers requiring manual setting adjustment expose personnel to hazardous tasks near the crushing chamber.

Is your operation losing potential revenue due to unreliable crushing? Are you seeking a solution that delivers consistent throughput, reduces maintenance windows, and provides a predictable feed for downstream processes? The right primary gold ore crushing equipment is the foundational investment for plantwide efficiency.

2. PRODUCT OVERVIEW: PRIMARY JAW CRUSHER FOR GOLD ORE PROCESSING

This heavyduty jaw crusher is engineered as the robust primary reduction unit for runofmine (ROM) gold ore. It is designed to accept large feed material (typically up to 80% of the gape dimension) and deliver a consistent, coarse product for secondary crushing or direct feed to a grinding circuit.

Operational Workflow:
1. ROM gold ore is fed via dump truck or loader into the vibrating grizzly feeder (optional), which bypasses fines directly to the product belt.
2. Oversize material enters the deep crushing chamber of the jaw crusher, where a powerful elliptical motion compresses ore against a stationary jaw plate.
3. Crushed material exits through an adjustable discharge opening, determining the product's top size.
4. The crushed product is conveyed to the next stage of your mineral processing plant.

Application Scope & Limitations:
Scope: Ideal for hard, abrasive gold ores with high compressive strength and quartz content. Suited for stationary plants or semimobile setups. Effective in both greenfield projects and retrofit upgrades.
Limitations: Not designed as a finecrushing unit. Requires competent feed regulation to prevent chamber packing. Maximum feed size is constrained by the machine's gape dimension.
