1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Are you facing persistent bottlenecks in your gold recovery circuit? Inconsistent grind size from your milling operation directly reduces leach efficiency and gold yield. Frequent liner replacements and unplanned maintenance on your grinding equipment cause costly production halts, while high energy consumption per ton of ore erodes your profit margins. Are abrasive, hardrock ores accelerating wear on critical components, leading to excessive spare parts inventory and operational risk? Your operation requires a reliable, efficient comminution solution engineered for longevity. Làm thế nào để bạn đạt được sự nhất quán, optimal liberation of gold particles while controlling operational costs and maximizing mill uptime? The answer lies in a purposebuilt Chinese Stamp Mill for gold mining.

2. TỔNG QUAN SẢN PHẨM

This product is a modern, industrially manufactured Chinese Stamp Mill, a mechanized gravityimpact crushing and grinding machine designed for the liberation of freemilling gold from quartz and other host rocks. It is not a historical replica but an engineered piece of mineral processing equipment built with contemporary materials and manufacturing standards.

Quy trình hoạt động:
1. Cho ăn: Runofmine hoặc quặng nghiền sơ cấp (<50mm) is fed into a mortar box.
2. Impact Grinding: Nâng tem nặng bằng máy móc (đôi giày) are released to drop onto the ore bed within the mortar box, repeatedly pulverizing the material through gravity impact.
3. Slurry Formation & Rửa: Water is introduced into the mortar box, creating a slurry of crushed material.
4. Phóng điện: The fine slurry washes over an internal screen, exiting the mill for subsequent gravity concentration (ví dụ., cống, bàn lắc).

Phạm vi ứng dụng & Hạn chế:
Lý tưởng cho: Small to mediumscale operations, cây thí điểm, or specific circuits targeting freemilling alluvial or hardrock gold deposits where cyanidefree processing is preferred or as a primary grinder ahead of leaching.
Hạn chế: Not suitable for ultrafine grinding requirements (<100 lưới). Efficiency decreases with highly clayey or sticky ores that can impede slurry flow. Requires a consistent feed size for optimal operation.

6. KỊCH BẢN ỨNG DỤNG

HardRock Quartz Vein Mining – West Africa Challenge:

A contractoroperated mine faced excessive downtime replacing worn hammers in their small ball mill circuit every three weeks due to highly abrasive quartz ore, halting production for a full day each time.

Giải pháp:

Implementation of a threestamp Chinese Stamp Mill with carbidetipped shoes as the primary grinder.

Kết quả:

Stamp shoe replacement interval extended to over four months of continuous operation. Combined with lower energy consumption, total grinding cost per ton was reduced by an estimated 28%. Liberated coarse gold was also recovered via an integrated catch tray before cyanidation.

Alluvial Processing Plant Upgrade – Southeast Asia Challenge:

A processing plant using rudimentary crushing methods experienced poor overall recovery due to inconsistent particle size fed to their shaking tables, leaving locked particles unrecovered.

Giải pháp:

Integration of a Chinese Stamp Mill into the circuit after primary scrubbing to provide a controlled, consistent grind size.

Kết quả:

Plant managers reported a much more uniform feed to concentration tables. Industry testing demonstrated improved liberation led to a measurable increase in overall gravity recovery yield by approximately 15%, paying back the equipment investment within one season.
