1. PEMBUKAAN PAINPOINT DRIVEN

Adakah anda menghadapi kesesakan yang berterusan dalam litar pemulihan emas anda? Inconsistent ore throughput, excessive liner and part wear, and unplanned maintenance downtime directly erode your profit margins. Each hour a stamp mill is offline for repairs or adjustment represents thousands in lost processing revenue. Tambahan pula, inefficient particle liberation can leave valuable gold locked in tailings, while high energy consumption per ton of ore processed squeezes operational budgets.

Are you asking how to:
Increase consistent throughput while managing variable ore hardness?
Reduce the frequency and cost of mechanical maintenance?
Improve overall recovery rates from complex ores?
Achieve predictable operating costs with lower energy consumption per ton?

A certified, modern stamp mill solution is engineered to address these exact operational challenges.

2. GAMBARAN KESELURUHAN PRODUK

This certified stamp mill is a heavyduty, mechanized milling system designed for the reliable crushing and grinding of goldbearing quartz rock to liberate values for subsequent recovery processes. It operates on the proven principle of dropping heavy weights (setem) ke bijih yang dimasukkan ke dalam kotak mortar.

Aliran Kerja Operasi:
1. Suapan: Runofmine atau bijih primer dihancurkan (<50mm) is continuously fed into the mortar box.
2. Penumbuk: Mechanically lifted stamps are released in a controlled cycle, melumatkan bijih terhadap acuan yang mengeras (mortar block) with repeated impact.
3. Basuh & Pelepasan: A continuous water flow through the mortar box washes the finely ground pulp (buburan) over an apron or through screens for discharge to downstream concentration (mis., pintu air, menggoncang meja).

Skop Permohonan & Batasan:
Skop: Ideal for small to mediumscale hard rock gold mining operations, loji perintis, and processing centers handling quartzdominant ores. Effective for both freemilling and some refractory ores requiring fine grinding.
Batasan: Not suitable for highclay or highly abrasive nongold ores without modification. Requires a consistent feed size and stable water supply. Operational noise and vibration necessitate proper site planning.
