1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Are you facing persistent bottlenecks in your gold processing circuit due to inefficient primary grinding? The performance of your initial size reduction stage directly dictates downstream recovery rates and overall plant profitability. Common challenges with conventional primary crushing and grinding setups include:

Thời gian ngừng hoạt động cao: Frequent liner changes and mechanical failures in jaw crushers or primary ball mills lead to unscheduled stoppages, tiêu tốn hàng trăm giờ sản xuất hàng năm.
Giải phóng dưới mức tối ưu: Inconsistent feed size from primary processing can cause poor gold particle exposure, trapping valuable material in waste rock and reducing overall cyanidation or gravity recovery yields by 515%.
Tiêu thụ năng lượng quá mức: Lớn hơn, oversized primary milling equipment operates at low efficiency, with a significant portion of input power converted to heat and noise rather than productive grinding work.
Chi phí nhân công bảo trì cao: The arduous, manual task of maintaining heavyduty primary crushers consumes skilled labor hours and increases safety exposure for your crew.

Is your operation sacrificing gold recovery and margin due to an unreliable or inefficient primary size reduction system? The solution lies in selecting the right foundational technology for consistent, controllable feed preparation.

2. TỔNG QUAN SẢN PHẨM

The Chinese Stamp Mill is a modern reinterpretation of a historically proven principle, engineered for robust primary crushing and coarse grinding in gold mining applications. This gravitydriven hammer mill is designed as a reliable, lowercapacity alternative or supplement for processing goldbearing quartz rock at the head of a milling circuit or within smallscale/artisanal operations.

Quy trình hoạt động:
1. Giới thiệu nguồn cấp dữ liệu: Runofmine (rom) or primarily crushed quartz ore (tiêu biểu <50mm) is fed into a vertical guide box.
2. Tác động theo trọng lực: Hàng loạt tem nặng được nâng lên một cách máy móc (wooden or metal rods shod with iron shoes) are released to drop onto the ore bed contained within a mortar box.
3. Giảm hạt: The repeated impact of the stamps fractures the ore through sheer force, progressively reducing it to a coarse sand consistency.
4. hình thành bùn & Phóng điện: Water is introduced into the mortar box, creating a slurry that passes through a fine screen at the discharge end. Vật liệu quá khổ vẫn còn để nghiền thêm, while the liberated slurry reports to downstream concentration (ví dụ., cống, bàn lắc).

Phạm vi ứng dụng & Hạn chế:
Lý tưởng cho: Smalltomedium scale operations, cây thí điểm, toll processing centers, or remote sites with limited access to grid power or complex maintenance infrastructure. Effective on freemilling gold ores hosted in brittle quartz matrices.
Hạn chế: Không thích hợp cho các hoạt động có trọng tải cao (>50 TPD thường). Less effective on clayrich, ướt, or highly ductile ores that absorb impact energy. Requires consistent ore feed size for optimal operation.
