1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Are you managing a highgrade gold operation where conventional crushing and grinding methods are eroding your profit margins? The challenges of processing hard rock gold ore are significant: inconsistent particle size distribution from primary crushers leading to poor liberation, excessive wear on grinding components from abrasive quartz, and high energy consumption per ton of ore milled. These factors directly impact your bottom line through increased downtime for liner changes, higher operational costs, and potential gold losses in coarse tailings. Làm thế nào để bạn đạt được sự nhất quán, highrecovery milling for premium ore bodies while controlling operational expenditure and maximizing the value of every ton? The solution requires a robust, precisionengineered approach to comminution.

2. TỔNG QUAN SẢN PHẨM

The Luxury Stamp Mill is a modern reinterpretation of the classic gravityimpact crushing principle, engineered for selective operations processing highvalue goldquartz veins and sulfide ores. It is designed for operations where preserving coarse free gold and minimizing overgrinding are critical to profitability.

Quy trình hoạt động:
1. Chuẩn bị thức ăn: Quặng cỡ (tiêu biểu 2" ĐẾN 1/2") from a primary jaw crusher is fed into a regulated feed hopper.
2. Nghiền tác động trọng lực: Camdriven heavyduty stamps (trọng lượng) are lifted and dropped onto the ore bed contained within a durable mortar box.
3. Giảm kích thước hạt & Amalgamation: The repeated impact fractures the ore along grain boundaries, liberating gold particles which can be captured via integrated amalgamation plates or direct collection.
4. Phóng điện & Phân loại: Crushed material passes through a grated screen at the mortar box discharge, with oversize recycled and fines reporting to downstream concentration processes (ví dụ., cống, bàn lắc).

Phạm vi ứng dụng & Hạn chế:
Lý tưởng cho: Small to mediumscale operations with hard rock lode deposits, khai thác thủ công và quy mô nhỏ (ASM) dự án chính thức hóa, custom milling facilities for highgrade ore, and historical site reprocessing.
Hạn chế: Not suitable for hightonnage, bulk mining operations (>200 TPD). Less effective for soft, quặng giàu đất sét gây đóng gói. Requires consistent feed sizing from primary crushing.

6. KỊCH BẢN ỨNG DỤNG

HighGrade Vein Mining Operation – West Africa

Thử thách: A midtier miner was experiencing >15% gold loss in coarse tailings from their hammer mill circuit when processing extremely hard quartz veins. Overgrinding also created slimes that hampered cyanidation efficiency.
Giải pháp: Installation of two parallel Luxury Stamp Mills configured with coarse discharge grates after primary jaw crushing.
Kết quả: Coarse free gold recovery via direct trapping improved by 22%. Sự phục hồi tổng thể của cây tăng thêm 9% due to improved particle liberation characteristics for the leach circuit. Energy costs per ton milled fell by an estimated 18%.

Historical Tailings Reprocessing Facility – North America

Thử thách: Retreating historical tailings required gentle but effective size reduction of slaglike material to liberate encapsulated gold without creating excessive ultrafines.
Giải pháp: A single lowspeed Luxury Stamp Mill was deployed as the primary grinder, replacing a small ball mill.
Kết quả: The impact crushing action proved more effective than tumbling abrasion on the brittle material. Gold liberation yield improved while reducing fines generation (35% TRONG 200 mesh fraction), enhancing downstream flotation kinetics. Maintenance costs were lower due to less abrasive wear compared to ball mill liners.
