1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Are you managing a small to midscale gold operation where consistent, lowcost comminution is critical to profitability? The challenges of processing hard rock gold ore are welldocumented: excessive energy consumption from oversized equipment, high maintenance costs from abrasive materials, and the logistical complexity of operating in remote locations. These factors directly erode your margin. When your primary crushing and grinding circuit is inefficient, you face not only increased power costs but also lost recovery from inadequate liberation. Làm thế nào để bạn đạt được độ tin cậy, fine grinding for effective cyanidation or gravity recovery without the capital outlay and operational overhead of a full ball mill circuit? The answer lies in a proven, purposebuilt technology: the modern Custom Stamp Mill.

2. TỔNG QUAN SẢN PHẨM

MỘT Custom Stamp Mill is a mechanized gravitydriven crushing mill designed specifically for the liberation of freemilling gold from quartz or other host rock. It modernizes the historic stamp battery principle with durable materials and precision engineering for continuous, lowtonnage operation.

Quy trình hoạt động:
1. Cho ăn: Quặng cỡ (tiêu biểu 2" from a primary jaw crusher) is fed into a enclosed mortar box.
2. Nghiền & mài: Nâng tem nặng bằng máy móc (đôi giày) are dropped in sequence onto the ore within the mortar box, pulverizing it by repeated impact.
3. Phóng điện & Phân loại: Pulverized material passes through a screen at the mortar box discharge, with oversize material recycled and fines reporting to subsequent gold recovery processes (ví dụ., cống, máy tập trung).

Phạm vi ứng dụng & Hạn chế:
Lý tưởng cho: Quặng vàng nghiền tự do, cây thí điểm, smallscale commercial operations (150 TPD), historical mine reprocessing, and locations with limited water or power infrastructure.
Hạn chế: Not suitable for refractory ores requiring fine grinding below 100 mesh for liberation, or for hightonnage operations exceeding 75 TPD. Performance is optimal on brittle, siliceous ores.
