عينة مطحنة الطوابع الصينية لتعدين الذهب
1. فتحة مدفوعة بنقطة الألم
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:
ارتفاع وقت التوقف التشغيلي: Frequent liner changes and mechanical failures in jaw crushers or primary ball mills lead to unscheduled stoppages, تكلف مئات ساعات الإنتاج سنويا.
التحرير دون الأمثل: 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%.
الاستهلاك المفرط للطاقة: أقدم, 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.
ارتفاع تكاليف عمالة الصيانة: 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. نظرة عامة على المنتج
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.
سير العمل التشغيلي:
1. مقدمة الأعلاف: Runofmine (ذاكرة للقراءة فقط) or primarily crushed quartz ore (عادة <50مم) is fed into a vertical guide box.
2. تأثير الجاذبية: سلسلة من الطوابع الثقيلة التي يتم رفعها ميكانيكيًا (wooden or metal rods shod with iron shoes) are released to drop onto the ore bed contained within a mortar box.
3. الحد من الجسيمات: The repeated impact of the stamps fractures the ore through sheer force, progressively reducing it to a coarse sand consistency.
4. تشكيل الطين & تسريح: Water is introduced into the mortar box, creating a slurry that passes through a fine screen at the discharge end. Oversize material remains for further crushing, while the liberated slurry reports to downstream concentration (على سبيل المثال, السدود, هز الجداول).
نطاق التطبيق & القيود:
مثالية ل: Smalltomedium scale operations, النباتات التجريبية, 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.
القيود: Not suitable for hightonnage operations (>50 TPD عادة). Less effective on clayrich, مبتل, or highly ductile ores that absorb impact energy. Requires consistent ore feed size for optimal operation.
