1. PYNPUNT GEDREWE OPENING

Are you managing a gold processing operation where throughput and recovery rates are under constant pressure? The limitations of your primary comminution and liberation circuit directly impact your bottom line. Common challenges with traditional stamp mill operations include:

Oormatige stilstand vir instandhouding: Frequent wear part replacement on individual stamps halts the entire milling line, costing hundreds of dollars per hour in lost production.
Inkonsekwente deeltjiegrootteverspreiding: Poorly calibrated drops or worn shoes create uneven grind sizes, leading to gold losses in tailings and reduced cyanidation or gravity recovery efficiency.
Hoë operasionele arbeidskoste: Manual monitoring, feeding, and adjustment of multiple stamps require significant skilled labor, increasing operational expenses and variability.
Inefficient Energy Utilization: Ouer, mechanically inefficient designs convert a disproportionate amount of power into heat and vibration rather than effective ore fracture.

Is your operation facing rising costs per ton and unpredictable maintenance cycles? What if you could implement a modern commercial stamp mill solution engineered to address these exact pain points with measurable improvements in availability and mineral liberation?

2. PRODUK OORSIG

The modern commercial stamp mill is a heavyduty, mechanized crushing device designed for the reliable reduction of goldbearing quartz ore to a sandlike consistency suitable for subsequent gravity separation or leaching processes. Ontwerp vir deurlopende, hoëtonnage-bedrywighede, it replaces antiquated singlestamp units with synchronized battery systems.

Operasionele werkvloei:
1. Beheerde voer: RunofMine (ROM) ore is consistently metered via an apron feeder into a centralized feed hopper.
2. Synchronized Percussion: A rotating camshaft lifts multiple (tipies 510) heavy iron stamps in a precise sequence, allowing them to drop onto iron mortars containing the ore.
3. Deurlopende Bevryding: Crushed material passes through fine screens integrated into each mortar box, ensuring only optimally sized particles exit the circuit.
4. Mishantering: The discharged sand is conveyed as a slurry to settling tanks or directly to concentration tables.

Toepassingsomvang & Beperkings:
Omvang: Ideal for freemilling gold ores where coarse gold liberation is critical; serves as a primary crusher and grinder in remote locations or smallerscale commercial mines where simplicity and robustness are prioritized over ultrafine grinding.
Beperkings: Not suitable for refractory ores requiring fine pulverization below 100 gaas. Operational noise and vibration levels require proper foundation engineering and site planning.
