1. فتحة مدفوعة بنقطة الألم

Are you facing persistent bottlenecks in your gold recovery circuit that directly impact your bottom line? لمديري المصانع والمقاولين الهندسيين, the crushing and grinding stage often presents critical challenges. Inconsistent feed size from primary crushers leads to frequent overloading of your stamp mill, causing unplanned downtime for maintenance and adjustment. Wear part consumption on shoes and dies becomes a significant, unpredictable cost, while achieving the optimal 100 mesh grind for efficient cyanidation or gravity recovery can be elusive with aging or undersized equipment. This results in lower overall recovery rates, higher energy costs per ton processed, and constant operational firefighting.

How do you stabilize this foundational stage of your operation? Can you reduce the total cost of ownership for your comminution equipment while improving throughput and recovery consistency? الحل يكمن في تحديد الحديث, heavyduty premium stamp mill engineered to address these exact industrial pain points.

2. نظرة عامة على المنتج

This premium stamp mill is a modern reinterpretation of a proven technology, designed for reliable, highvolume crushing and grinding of goldbearing quartz ore. It functions as a core component in hard rock gold processing plants, typically positioned after primary jaw crushing.

سير العمل التشغيلي:
1. مقدمة الأعلاف: خام الحجم (عادة 2 بوصة) is fed continuously into the mortar box via a regulated feeder.
2. الإيقاع الميكانيكي: A camshaft lifts heavy cast iron stamps (5 ل 10 لكل مطحنة) in a rotating sequence, dropping them onto the ore bed within the mortar box.
3. طحن & تحرير: The repeated impact pulverizes the ore against hardened dies. A controlled water flow creates a slurry that passes through a fine screen at the mortar box's end.
4. تفريغ الطين: The ground slurry reports to the next stage—either direct cyanidation tanks or concentration via shaking tables/centrifugal concentrators.

نطاق التطبيق & القيود:
نِطَاق: Ideal for medium to hightonnage operations processing hard, abrasive quartz veins where simple operation and mechanical reliability are prioritized. Excellent for remote sites with limited technical support.
القيود: Not suitable for soft or clayrich ores that cause packing. Requires consistent feed sizing from upstream crushing. Physical footprint and foundation requirements are significant compared to some modern ball mills.
