1. PEMBUKAAN PAINPOINT DRIVEN

Are you facing persistent bottlenecks in your primary gold ore processing circuit? Operational data from hard rock gold mines consistently highlights three critical challenges: excessive downtime for liner changes and maintenance, inconsistent particle size distribution leading to poor cyanide leach recovery, and escalating energy costs per ton of ore processed. Isu ini secara langsung memberi kesan kepada keuntungan anda, translating to lost production hours, suboptimal gold yield, and shrinking profit margins.

How do you maintain throughput when dealing with increasingly complex ore bodies? Can your comminution circuit adapt without requiring a complete plant overhaul? The solution lies not in incremental adjustments, but in the foundational efficiency of your primary crushing and grinding equipment. Yang mantap, wellengineered stamp mill remains a proven asset for specific gold mining operations seeking reliable, mechanical simplicity and high recoveries from freemilling ores.

2. GAMBARAN KESELURUHAN PRODUK

This product line comprises heavyduty Stamp Mills for gold ore processing. Also known as a stamp battery or crushing stamp, this equipment utilizes a gravitydriven, mechanical pounding action to liberate gold from host rock.

Aliran Kerja Operasi:
1. Suapan: Sized ore (biasanya 2" ke 3") is fed into a mortar box.
2. Menghancurkan & Pengisaran: Camdriven stamps (weighted rods with mallets) are lifted and dropped onto the ore within the mortar box.
3. Pembentukan Slurry: Water is introduced during the process, creating a slurry of crushed material.
4. Pelepasan: The fine slurry passes through a perforated screen at the mortar box's end.
5. Konsentrasi: The discharged slurry flows over amalgamation plates or to downstream concentration tables for gold recovery.

Skop Permohonan & Batasan:
Sesuai Untuk: Small to mediumscale operations processing freemilling gold ores (where gold is not encapsulated in sulfides), remote sites with limited access to grid power, or operations prioritizing mechanical reliability over ultrafine grinding.
Batasan: Less efficient on refractory ores requiring fine liberation. Generally has a lower throughput capacity per footprint compared to modern ball mills or HPGRs in largescale operations. Requires consistent ore feed sizing for optimal performance.
