1. PEMBUKAAN PAINPOINT DRIVEN

Are your gold recovery operations constrained by inefficient primary grinding? Saiz suapan tidak konsisten, memakai pelapik yang berlebihan, and unplanned maintenance on your comminution equipment directly impact your bottom line. Consider these common challenges in gold ore processing:
Kos Operasi yang Tinggi: Frequent replacement of grinding media and mill liners due to abrasive ore results in significant consumable expenses and production halts.
Saiz Kisar Tidak Konsisten: Variable feed material leads to fluctuating particle size output from your primary mill, reducing downstream cyanidation or gravity recovery efficiency.
Excessive Downtime: Traditional mill designs require lengthy, laborintensive shutdowns for liner changes and maintenance, costing valuable production time.
Ketidakcekapan Tenaga: Older milling technology may consume excessive power per ton of ore processed, menjadikan tenaga sebagai salah satu kos tidak terkawal terbesar anda.
Had Kebolehskalaan: Rigid mill configurations struggle to adapt to changing ore body characteristics or increased throughput targets without major capital investment.

Adakah operasi anda mencari yang mantap, reliable primary grinding solution engineered to reduce cost per ton and maximize gold liberation?

2. GAMBARAN KESELURUHAN PRODUK

The China Stamp Mill for gold mining is a modernized, heavyduty mechanized crushing and grinding apparatus designed for the primary comminution of goldbearing quartz rock and ores. It functions as a core piece of mineral processing equipment, applying repetitive percussive force to reduce runofmine (ROM) ore to a consistent, liberatable size for subsequent concentration processes.

Aliran Kerja Operasi:
1. Pengenalan suapan: bijih ROM (typically sized below 100mm) is continuously fed into a centralized feed hopper.
2. Percussive Grinding: Satu siri setem berat yang diangkat secara mekanikal (berat) are released in a controlled cycle, dropping onto the ore bed contained within a durable mortar box.
3. Pengurangan Saiz Zarah: The repeated impact fractures the ore along natural grain boundaries, efficiently liberating gold particles without excessive overgrinding.
4. Pelepasan Buburan: Ground material is washed through a discharge screen with water, creating a slurry of target particle size that reports to downstream shaking tables, penumpu emparan, or leaching circuits.

Skop Permohonan & Batasan:
Skop: Ideal for freemilling gold ores where gravity recovery is viable; effective for smalltomedium scale operations (5500 TPD); suitable for remote sites due to robust mechanical design.
Batasan: Less efficient on clayrich or highly weathered ores that cause packing; not a finegrinding solution—typically produces product in the 20100 mesh range; requires consistent water supply for slurry handling.

6. SENARIO APLIKASI

Alluvial/Vein Gold Processing Plant Challenge:

A West African operation processing hard rock quartz veins faced high energy costs and rapid wear from their small ball mill circuit. Downstream gravity recovery was inefficient due to poor and inconsistent primary grind.

Penyelesaian:

Implementation of two parallel CSM300 China Stamp Mills as the primary grinding stage ahead of existing shaking tables.

Keputusan:

Achieved a target grind of 80%65 mesh consistently. Gravity recovery rate improved from ~55% to over 70%. Combined energy and media savings reduced processing cost by an estimated $18/tonne.

Secondary Grinding Circuit Feed Preparation Challenge:

A South American mine using a cyanidation plant required finer feed but their primary jaw crusher produced too many coarse slabs causing bottlenecks in the secondary roller mill.

Penyelesaian:

Installation of a single China Stamp Mill as an intermediate crushing/grinding stage between the jaw crusher and the roller mill.

Keputusan:

The stamp mill effectively broke down coarse slabs into granular feed ideal for the roller mill. This balanced the load across the circuit, increasing overall plant throughput by approximately 22%.
