1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Bạn có đang gặp phải tình trạng tắc nghẽn dai dẳng trong quá trình phục hồi vàng của mình không?? Inefficient primary grinding and liberation can directly undermine your entire operation's profitability. Common challenges with conventional crushing and grinding setups include:
Thời gian ngừng hoạt động cao: Frequent liner changes and unplanned maintenance in primary crushers and ball mills halt your processing line, gây thiệt hại hàng ngàn mỗi giờ trong sản xuất bị mất.
Giải phóng vàng dưới mức tối ưu: Inconsistent particle size from primary grinding limits cyanide leach or gravity recovery efficiency, leaving payable gold locked in tailings.
Tiêu thụ năng lượng quá mức: Overgrinding to achieve target liberation consumes disproportionate power, one of the highest cost centers in mineral processing.
High Media & Liner Wear Costs: Abrasive ore types lead to accelerated consumption of grinding media and mill liners, driving up consumable expenses.
Complexity in Wet Ore Processing: Handling clayrich or highmoisture feed material can lead to clogging, thông lượng giảm, and increased handling costs.

Is your current primary comminution circuit a source of variable performance and unpredictable cost? What if a robust, purposebuilt solution could provide consistent, coarse liberation with lower operational complexity?

2. TỔNG QUAN SẢN PHẨM

The Chinese Stamp Mill is a modern reinterpretation of a historically proven principle for coarse gold ore liberation. This gravityimpact crushing equipment is engineered for primary or secondary reduction of goldbearing quartz rock and sulphide ores.

Quy trình hoạt động:
1. Giới thiệu nguồn cấp dữ liệu: Runofmine (rom) ore is fed into a sturdy mortar box.
2. GravityDriven Impact: Nâng tem nặng bằng máy móc (trọng lượng) được thả rơi xuống lòng quặng.
3. Continuous Pulverization: The repeated impact of multiple stamps reduces the ore to a coarse sand consistency.
4. WaterAssisted Discharge: A controlled flow of water flushes the crushed material through a perforated screen plate for classification.
5. Gravity Concentration Ready Output: The discharged slurry presents optimally liberated coarse gold particles for immediate recovery via downstream concentrators (ví dụ., bàn lắc, máy tập trung ly tâm).

Phạm vi ứng dụng & Hạn chế:
Lý tưởng cho: Small to mediumscale hard rock gold operations, cây thí điểm, thủ công & smallscale mining (ASM) dự án chính thức hóa, and processing centers dealing with freemilling ores.
Rất phù hợp cho: Remote sites with limited grid power or where operational simplicity is paramount.
Hạn chế: Not designed for fine grinding to ultrafine sizes (<100 lưới). Efficiency decreases with highly ductile or claybound ores without feed preparation.
