1. PYNPUNT GEDREWE OPENING

Bestuur jy goudherwinningsbedrywighede wat deur inkonsekwente deurset belas word, excessive downtime for maintenance, en stygende bedryfskoste? Key challenges with traditional comminution and liberation processes directly impact your bottom line:
Hoë bedryfsuitgawes: Excessive energy consumption per ton of ore processed and frequent replacement of wear parts like dies and shoes.
Onbeplande stilstand: Mechanical failures in camshafts or bearings halt entire processing lines, duisende per uur in verlore produksie kos.
Ondoeltreffende Bevryding: Inconsistent particle size distribution from the crushing stage limits optimal gold exposure to leaching agents, algehele herstelkoerse te verminder.
Arbeidsintensiteit & Veiligheid: Manual feeding and monitoring of heavy stamp batteries increase labor costs and present safety risks.
Skaalbaarheidsbeperkings: Difficulty in reliably scaling operations to process highergrade or harder ore bodies without major capital investment.

How can you achieve more predictable throughput, koste per ton verminder, and improve gold liberation without constant mechanical intervention? Die oplossing lê in gemoderniseer, heavyduty stamp mill technology engineered for commercialscale reliability.

2. PRODUK OORSIG

Our HeavyDuty Industrial Stamp Mill is a mechanized crushing system designed for the primary liberation of gold from quartz and hard rock ore. It operates on the principle of repetitive percussive crushing via weighted stamps dropped onto ore fed into a mortar box.

Operasionele werkvloei:
1. Voer: Runofmine or primarycrushed ore is consistently fed into the stamp mill’s mortar box via a regulated conveyor or feeder system.
2. Verpletterend: Mechanically lifted cast iron or steel stamps are released in a controlled sequence, pulverizing the ore against a hardened anvil block (sterf) within the mortar box.
3. Was & Ontslag: A continuous flow of water washes the finely crushed slurry through a perforated screen plate at the mortar box's end, ensuring continuous operation and proper particle size discharge.
4. Konsentrasie: The discharged slurry is routed to downstream concentration systems such as sluices, skud tafels, or amalgamation plates for gold recovery.

Toepassingsomvang & Beperkings:
Omvang: Ideal for small to midscale hard rock gold mining operations, loodsaanlegte, and processing centers dealing with quartz veins and sulphide ores requiring physical liberation. Effective as a primary or secondary crusher in a dedicated gravity recovery circuit.
Beperkings: Nie geskik vir nat nie, kleiryke materiaal sonder om vooraf te skrop; requires a consistent feed size (tipies 2" aan 4"); less energyefficient than some modern roller crushers for very highvolume operations (>500 TPD).
