1. PEMBUKAAN PAINPOINT DRIVEN

Adakah anda menghadapi kesesakan berterusan dalam litar pemulihan emas anda yang secara langsung memberi kesan kepada keuntungan anda? Untuk pengurus loji dan kontraktor kejuruteraan, the crushing and grinding stage often presents critical challenges. Inconsistent feed size from primary crushers leads to frequent overloading of your stamp mill, causing unplanned downtime for maintenance and adjustment. Wear part consumption on shoes and dies becomes a significant, unpredictable cost, while achieving the optimal 100 mesh grind for efficient cyanidation or gravity recovery can be elusive with aging or undersized equipment. This results in lower overall recovery rates, higher energy costs per ton processed, and constant operational firefighting.

How do you stabilize this foundational stage of your operation? Can you reduce the total cost of ownership for your comminution equipment while improving throughput and recovery consistency? Penyelesaiannya terletak pada menentukan moden, heavyduty premium stamp mill engineered to address these exact industrial pain points.

2. GAMBARAN KESELURUHAN PRODUK

This premium stamp mill is a modern reinterpretation of a proven technology, designed for reliable, highvolume crushing and grinding of goldbearing quartz ore. It functions as a core component in hard rock gold processing plants, typically positioned after primary jaw crushing.

Aliran Kerja Operasi:
1. Pengenalan suapan: Bijih bersaiz (biasanya 2 inci) is fed continuously into the mortar box via a regulated feeder.
2. Perkusi Mekanikal: A camshaft lifts heavy cast iron stamps (5 ke 10 per mill) in a rotating sequence, dropping them onto the ore bed within the mortar box.
3. Pengisaran & Pembebasan: The repeated impact pulverizes the ore against hardened dies. A controlled water flow creates a slurry that passes through a fine screen at the mortar box's end.
4. Pelepasan Buburan: The ground slurry reports to the next stage—either direct cyanidation tanks or concentration via shaking tables/centrifugal concentrators.

Skop Permohonan & Batasan:
Skop: Ideal for medium to hightonnage operations processing hard, abrasive quartz veins where simple operation and mechanical reliability are prioritized. Excellent for remote sites with limited technical support.
Batasan: Not suitable for soft or clayrich ores that cause packing. Requires consistent feed sizing from upstream crushing. Physical footprint and foundation requirements are significant compared to some modern ball mills.
