1. PYNPUNT GEDREWE OPENING

Are your gold recovery operations constrained by inconsistent throughput, excessive energy consumption per ton, or unplanned maintenance halting your entire milling circuit? Legacy stamp mill configurations often lead to three critical challenges:

Suboptimal Liberation & Herstel: Inefficient crushing and grinding can fail to fully liberate gold from complex ores, leaving measurable value in your tailings and directly impacting your bottomline recovery rate.
High Operational Expenditure: Aging stamp mills with manual controls consume disproportionate power for their output. Unoptimized wear part cycles lead to frequent, costly replacements and associated labor downtime.
Inflexible Plant Design: Fixedconfiguration equipment struggles to adapt to varying ore hardness and feed grades, forcing operations to run at a constant, often inefficient, pace regardless of feedstock variability.

How do you increase tonnage throughput while improving recovery consistency? Can you reduce energy and maintenance costs without a complete plant overhaul? Die antwoord lê in 'n doelontwerp, customized stamp mill assembly plant.

2. PRODUK OORSIG

'n moderne Customized Stamp Mill Gold Mining Assembly Plant is not a single machine but an integrated processing system engineered for the specific comminution (verpletterend) of goldbearing ore. It replaces antiquated, standalone stamp batteries with a synchronized circuit designed for reliability and efficiency.

Operasionele werkvloei:
1. Primêre voer & Regulation: Runofmyne (ROM) ore is fed via a regulated conveyor system to a primary scalping or jaw crusher for initial size reduction.
2. Controlled Stamp Milling: Precrushed ore is fed uniformly to a battery of modernized stamp mills. Each camdriven stamp (or pestle) is precisely weighted and dropped in a controlled cycle onto the ore within a hardened mortar box.
3. Misvorming & Ontslag: Crushed material mixes with water in the mortar box to form a slurry, which passes through a discharge screen with precise aperture sizing, ensuring only sufficiently liberated material exits the circuit.
4. Gravity Concentration Ready: The discharged slurry, containing nowliberated gold particles, is directed to downstream processes like sluices, skud tafels, or centrifugal concentrators for separation.

Toepassingsomvang & Beperkings:
Omvang: Ideal for smalltomedium scale hard rock gold mining operations, particularly where ore is amenable to gravity recovery methods. Effective for both freemilling ores and as a primary crusher for refractory ores ahead of leaching.
Beperkings: Not suitable for hightonnage operations exceeding several hundred TPD where ball mill/cyanide circuits are more economical. Performance is highly dependent on correct customization for local ore characteristics.
