1. فتحة مدفوعة بنقطة الألم

Are your gold recovery operations constrained by inefficient primary grinding? حجم التغذية غير متناسق, ارتداء بطانة المفرطة, and unplanned maintenance on your comminution equipment directly impact your bottom line. Consider these common challenges in gold ore processing:
التكلفة التشغيلية العالية: Frequent replacement of grinding media and mill liners due to abrasive ore results in significant consumable expenses and production halts.
حجم الطحن غير متناسق: Variable feed material leads to fluctuating particle size output from your primary mill, reducing downstream cyanidation or gravity recovery efficiency.
التوقف المفرط: Traditional mill designs require lengthy, laborintensive shutdowns for liner changes and maintenance, costing valuable production time.
عدم كفاءة الطاقة: Older milling technology may consume excessive power per ton of ore processed, جعل الطاقة واحدة من أكبر التكاليف التي لا يمكن السيطرة عليها.
قيود قابلية التوسع: Rigid mill configurations struggle to adapt to changing ore body characteristics or increased throughput targets without major capital investment.

2. نظرة عامة على المنتج

The China Stamp Mill for gold mining is a modernized, heavyduty mechanized crushing and grinding apparatus designed for the primary comminution of goldbearing quartz rock and ores. It functions as a core piece of mineral processing equipment, applying repetitive percussive force to reduce runofmine (ذاكرة للقراءة فقط) خام إلى متسقة, liberatable size for subsequent concentration processes.

سير العمل التشغيلي:
1. مقدمة الأعلاف: خام ROM (typically sized below 100mm) is continuously fed into a centralized feed hopper.
2. Percussive Grinding: سلسلة من الطوابع الثقيلة التي يتم رفعها ميكانيكيًا (الأوزان) are released in a controlled cycle, dropping onto the ore bed contained within a durable mortar box.
3. تخفيض حجم الجسيمات: يؤدي التأثير المتكرر إلى كسر الخام على طول حدود الحبوب الطبيعية, efficiently liberating gold particles without excessive overgrinding.
4. تفريغ الطين: Ground material is washed through a discharge screen with water, creating a slurry of target particle size that reports to downstream shaking tables, مكثفات الطرد المركزي, or leaching circuits.

نطاق التطبيق & القيود:
نِطَاق: Ideal for freemilling gold ores where gravity recovery is viable; effective for smalltomedium scale operations (5500 TPD); suitable for remote sites due to robust mechanical design.
القيود: Less efficient on clayrich or highly weathered ores that cause packing; not a finegrinding solution—typically produces product in the 20100 mesh range; يتطلب إمدادات مياه ثابتة للتعامل مع الملاط.

6. سيناريوهات التطبيق

Alluvial/Vein Gold Processing Plant Challenge:

A West African operation processing hard rock quartz veins faced high energy costs and rapid wear from their small ball mill circuit. Downstream gravity recovery was inefficient due to poor and inconsistent primary grind.

حل:

Implementation of two parallel CSM300 China Stamp Mills as the primary grinding stage ahead of existing shaking tables.

نتائج:

Achieved a target grind of 80%65 mesh consistently. Gravity recovery rate improved from ~55% to over 70%. Combined energy and media savings reduced processing cost by an estimated $18/tonne.

Secondary Grinding Circuit Feed Preparation Challenge:

A South American mine using a cyanidation plant required finer feed but their primary jaw crusher produced too many coarse slabs causing bottlenecks in the secondary roller mill.

حل:

Installation of a single China Stamp Mill as an intermediate crushing/grinding stage between the jaw crusher and the roller mill.

نتائج:

The stamp mill effectively broke down coarse slabs into granular feed ideal for the roller mill. This balanced the load across the circuit, increasing overall plant throughput by approximately 22%.
