1. PYNPUNT GEDREWE OPENING

Are you managing a gold processing operation where inconsistent throughput, hoë instandhoudingskoste, and unpredictable recovery rates are eroding your margins? Key operational challenges with traditional comminution and liberation circuits include:

Oormatige stilstand: Unplanned stoppages for liner changes and mechanical repairs can halt your entire milling circuit for 824 ure, duisende in verlore produksie per geleentheid kos.
Inkonsekwente slyp & Swak Bevryding: Variable feed size and worn components lead to an uneven grind. Insufficient liberation of gold from host rock directly caps your recovery rate, waardevolle materiaal in die uitskot agterlaat.
Hoë bedryfsuitgawes: Consumable wear parts (voerings, skoene, sterf), hoë energieverbruik per ton verwerk, and laborintensive operation create a significant ongoing cost burden.
Omgewing & Veiligheidsnakomingsrisiko's: Dust generation, slurry spillage, and noise levels present ongoing challenges for meeting ISO 14001 and OHSAS 45001 standaarde, risking fines and operational licenses.

Is your current stamp mill or primary crusher delivering the predictable, costeffective performance required for profitable gold extraction? The solution lies in precisionengineered equipment designed for reliability and optimal mineral liberation.

2. PRODUK OORSIG

The ISO Certified Stamp Mill is a modern reinterpretation of a proven technology, engineered for efficient gold ore processing in mediumscale operations. It functions as a core component for primary crushing and coarse grinding, facilitating the initial liberation of freemilling gold.

Operasionele werkvloei:
1. Voer Inleiding: Runofmyne (ROM) ore is fed into a robust hopper, regulating flow onto the feed table.
2. Meganiese perkussie: Camdrive seëls (or hammers) are lifted in sequence and dropped onto the ore placed on a durable die shoe/block assembly.
3. Deeltjiereduksie: The repeated impact fractures the ore particles through compressive force.
4. Misvorming & Ontslag: Crushed material is washed over a discharge screen with water; fine particles pass through as slurry for further concentration (bv., via sluices or shaking tables), while oversize material is recirculated.

Toepassingsomvang & Beperkings:
Ideaal vir: Processing freemilling alluvial or hard rock ores where coarse to medium grinding is sufficient for initial gold liberation. Suited for operations processing 10500 ton per dag.
Beperkings: Not suitable for refractory ores requiring ultrafine grinding or complex chemical treatment. Performance is optimal with consistent feed size distribution.
