1. PEMBUKAAN PAINPOINT DRIVEN

Is your gold recovery operation constrained by persistent bottlenecks and escalating costs? Untuk pengurus loji dan kontraktor kejuruteraan, the crushing and grinding circuit is often the source of critical inefficiencies that directly impact the bottom line. Cabaran biasa dengan peralatan comminusi tradisional termasuk:

Masa Henti Berlebihan untuk Penyelenggaraan: Frequent liner changes and unplanned repairs on critical components halt production, menelan belanja beribu-ribu sejam dalam pengeluaran yang hilang.
Taburan Saiz Zarah Tidak Konsisten: Poorly calibrated or worn equipment yields uneven ore feed to concentration processes, mengurangkan keseluruhan kadar pemulihan emas.
Penggunaan Tenaga Tinggi setiap Tan: Older stamp mill designs and inefficient drives lead to unsustainable power costs, perbelanjaan operasi utama.
Operasi Intensif Buruh & Pemantauan: Reliance on manual adjustments and sampling increases labor costs and introduces human error, affecting process stability.
Had Kebolehskalaan: Difficulty in efficiently scaling operations to process highergrade zones or increased ore volumes without major capital redesign.

Are you seeking a robust solution that enhances throughput predictability, reduces total operating cost per ton, and delivers consistent grind for optimal cyanidation or gravity recovery? The evolution of the modern stamp mill addresses these exact operational challenges.

2. GAMBARAN KESELURUHAN PRODUK: HeavyDuty Gravity Discharge Stamp Mill

This product is a modern, industrialgrade stamp mill engineered for the continuous crushing and fine grinding of goldbearing ore. It is designed as a core component within a hard rock gold processing plant, typically following primary jaw crushing.

Aliran Kerja Operasi:
1. Pengenalan suapan: Bijih bersaiz (biasanya 2") is fed uniformly into the mortar box via a regulated feed system.
2. GravityPowered Percussion: Satu siri setem berat yang diangkat secara mekanikal (kasut) are released to drop onto the ore bed within the mortar box, applying repeated impact force.
3. Pengurangan Saiz Zarah: Ore is fractured by direct impact and ground via attrition between particles beneath the stamp shoe.
4. Pelepasan Buburan: Finely ground material is washed through a perforated screen plate at the mortar box end by a continuous water flow, creating a slurry for subsequent concentration stages.

Skop Permohonan & Batasan:
Skop: Ideal for freemilling gold ores where liberation occurs at relatively coarse grinds. Highly effective in remote operations due to mechanical simplicity and reliability. Suited for both smallscale commercial mining and larger modular plant configurations.
Batasan: Not optimal for ultrafine grinding requirements (<100 mesh) or highly abrasive, lowgrade deposits where wear costs may be prohibitive. Requires a consistent feed size and controlled water volume for optimal operation.
