1. PEMBUKAAN PAINPOINT DRIVEN

Adakah anda menguruskan operasi pemulihan emas yang dihalang oleh pengeluaran yang tidak konsisten, masa henti penyelenggaraan yang berlebihan, dan peningkatan kos operasi? In hard rock gold mining, the crushing and liberation of ore is a critical bottleneck. Common challenges with conventional stamp mills or primary crushing circuits include:

Masa Henti Operasi yang Tinggi: Perubahan pelapik yang kerap, mechanical failures, and unplanned stops can reduce plant availability by 1525%, directly impacting production targets.
Pembebasan Emas yang tidak cekap: Inconsistent particle size distribution from worn or poorly calibrated equipment leads to suboptimal recovery in downstream processes like cyanidation or gravity concentration.
Penggunaan Tenaga Berlebihan: Lebih tua, mechanically inefficient crushing systems consume disproportionate power per ton of ore processed, a significant and growing lineitem cost.
Buruh Tinggi & Kos penyelenggaraan: Pemakanan manual, constant mechanical adjustment, and reactive repair schedules demand skilled labor and drive up total cost of ownership.

Adakah operasi anda mencari yang mantap, highcapacity solution to reliably process bulk tonnages of goldbearing quartz ore while controlling costs and maximizing recovery?

2. GAMBARAN KESELURUHAN PRODUK

The modern Bulk Stamp Mill is a heavyduty, mechanized milling system designed for the primary crushing and coarse grinding of gold ores at a production scale. It serves as a core component in mineral processing plants where reliable, highvolume size reduction is required.

Aliran Kerja Operasi:
1. Suapan Terkawal: Runofmine (ROM) ore is uniformly fed via conveyor into the mill's feed hopper.
2. Perkusi Mekanikal: Satu siri setem berat yang diangkat secara mekanikal (Hammers) are dropped onto the ore bed contained within a mortar box.
3. Pembebasan & Pelepasan: Hentaman berulang memecah bijih; crushed material passes through a discharge screen grate, memastikan saiz zarah terkawal.
4. Pengangkutan Slurry: The crushed product is typically mixed with water to form a slurry for transport to secondary grinding or direct leaching circuits.

Skop Permohonan & Batasan:
Sesuai Untuk: Hightonnage processing of freemilling gold ores (particularly quartz veins), primary crushing circuits, and operations requiring simple, robust technology with lower technical oversight.
Batasan: Less suitable for very hard, abrasive ores without frequent liner maintenance. Not intended for fine grinding; operates most effectively as part of an integrated circuit with secondary processing.
