1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Quản lý hoạt động chế biến vàng đòi hỏi phải cân bằng thông lượng, sự hồi phục, và chi phí hoạt động. Traditional comminution methods often fall short, creating significant bottlenecks. Bạn có đang phải đối mặt với những thử thách dai dẳng này?

Tiêu thụ năng lượng cao & Trị giá: Conventional ball mills and crushers are energyintensive, with power costs consuming a disproportionate share of your operating budget.
Mercury Amalgamation Dependency: Inefficient liberation of gold from ore drives reliance on hazardous mercury amalgamation in the concentration stage, posing severe environmental and health liabilities.
Excessive Water Usage & Quản lý chất thải: Wet milling processes demand large volumes of water and create slurry tailings that are costly to contain and remediate.
Operational Downtime for Maintenance: Thay đổi lớp lót thường xuyên, hỏng ổ trục, and unplanned stops in continuous systems directly impact tonnage processed and profitability.
Low Recovery Rates from Complex Ores: Inadequate particle size reduction fails to fully liberate fine gold particles locked within host rock, leaving revenue in the tailings.

What if your crushing and grinding circuit could address these issues simultaneously, reducing both operational expense and environmental footprint?

2. TỔNG QUAN SẢN PHẨM: ECOFRIENDLY MODULAR STAMP MILL

The EcoFriendly Modular Stamp Mill is a modern reinterpretation of the classic gravityimpact crushing principle, engineered for selective milling of goldbearing quartz veins and hard rock ores. It is designed as a drycrushing or minimalwater addition system to facilitate mercuryfree gold recovery.

Quy trình hoạt động:
1. Chuẩn bị thức ăn: Runofmine hoặc quặng nghiền sơ cấp (<50mm) is fed into a sealed hopper.
2. GravityImpact Milling: Tem hạng nặng Camdriven (búa) repeatedly drop onto the ore bed contained within a hardened steel mortar box, pulverizing material through controlled impact.
3. Phân loại & Tái chế: Crushed material passes through a replaceable screen grate at the mortar box exit. Oversize material is recycled; correctly sized material discharges for concentration.
4. Dry Processing Pathway: The milled, dry product is conveyed directly to downstream electrostatic, airgravity, or dry magnetic separators.

Phạm vi ứng dụng & Hạn chế:
Lý tưởng cho: Hoạt động vừa và nhỏ (150 TPD), vein mining, cây thí điểm, những địa điểm xa xôi với khả năng tiếp cận nguồn nước hạn chế, and regions with strict environmental regulations prohibiting mercury or cyanide.
Best Suited Ore Types: Freemilling gold in quartz, sulphideassociated ores (postroasting), and other brittle materials.
Hạn chế: Not optimal for highclay content ores (nguyên nhân đóng gói), very hightonnage operations (>100 TPD), or where ultrafine grinding (<100 lưới) is required as a standalone solution.

6. KỊCH BẢN ỨNG DỤNG

thủ công & Khai thác quy mô nhỏ (ASM) Formalization Project – West Africa

Thử thách: A governmentsponsored project needed to replace hundreds of manual mortarandpestle and mercurydependent grinding sites with a scalable, cleaner technology that maintained simplicity but drastically reduced toxic emissions.
Giải pháp: Deployment of semimobile EFM5 stamp mill units at centralized processing hubs. Each unit served multiple mining cooperatives.
Kết quả: Field data shows an average gold recovery increase of 22% due to improved liberation. Mercury use was eliminated at equipped hubs within six months.

Remote Hard Rock Exploration Camp – Canadian Shield

Thử thách: An exploration company required onsite bulk sampling and pilot processing but had no access to water or grid power at the drill site. Transporting wet samples was prohibitively expensive.
Giải pháp: Installation of one EFM10 stamp mill powered by a hybrid solardiesel generator system coupled to a dry shaking table.
Kết quả: The system processed over 500 tons of drill core reject material onsite, providing critical metallurgical data without water infrastructure. Power fuel costs were reduced by an estimated $15,000 during the campaign versus running a dieselpowered wet mill.
