1. PAINPOINT DRIVEN OPENING

Are you facing persistent challenges in your primary gold ore processing circuit? The limitations of traditional comminution and liberation methods directly impact your bottom line. Consider these common operational hurdles:
Low Gold Recovery Rates: Inefficient liberation of gold from quartz or sulfide matrices, leaving payable values in your tailings.
High Operational Downtime: Frequent maintenance stops due to the abrasive nature of ore, wearing out components and halting production.
Excessive Energy Consumption: Older crushing and grinding methods consuming disproportionate power per ton of ore processed.
Inconsistent Throughput & Grade Control: Difficulty maintaining a steady, fine grind size essential for optimal cyanidation or gravity recovery.
High Total Cost of Ownership: The cumulative cost of replacement parts, labor for repairs, and energy outweighing the initial equipment savings.

Is your operation sacrificing recovery and profitability due to an inefficient primary grinding solution? The right industrial stamp mill for gold mining addresses these exact pain points.

2. PRODUCT OVERVIEW

Our heavyduty stamp mill is a mechanized gravitydriven crushing mill designed for the primary liberation of gold from hard rock ore. It functions as a reliable, highimpact pulverizer, ideal for operations where simplicity, durability, and coarse to mediumfine grinding are priorities.

Operational Workflow:
1. Feed: Runofmine or primary crushed ore (<50mm) is fed into a sealed mortar box.
2. Crushing & Grinding: Mechanically lifted stamps (5002000+ lbs each) are sequentially dropped onto the ore, pulverizing it by repeated impact.
3. Wash & Discharge: A continuous flow of water washes the finely crushed slurry through a perforated plate (screen), discharging it for subsequent concentration.

Application Scope & Limitations:
Ideal For: Processing freemilling gold ores, pilot plants, small to mediumscale operations, and regions with limited grid power or technical infrastructure. Effective as a primary grinder ahead of shaking tables or centrifugal concentrators.
Limitations: Not suitable for ultrafine grinding (100 TPD). Requires competent foundation design due to dynamic loads.
