مطحنة الطوابع السائبة صانع تعدين الذهب
1. فتحة مدفوعة بنقطة الألم
هل عمليات استرداد الذهب الخاصة بك مقيدة بسبب عدم كفاءة التكسير والطحن الأولي؟? تخلق مصانع الطوابع القديمة والمعدات صغيرة الحجم اختناقات مستمرة تؤثر بشكل مباشر على أرباحك النهائية. النظر في هذه التحديات المشتركة:
تكاليف تشغيلية عالية: الاستهلاك المفرط للطاقة لكل طن من الخام المعالج والمتكرر, unplanned maintenance on worn stamps and dies drain profitability.
إنتاجية غير متناسقة & استعادة: Variable feed size and manual adjustments lead to uneven particle liberation, causing valuable gold to be locked in oversized material or lost as fines.
التوقف المفرط: طويلة, laborintensive die replacement and alignment procedures halt your entire milling circuit, costing thousands in lost production per hour.
قيود قابلية التوسع: Older stamp mill designs cannot easily adapt to increased ore volume or harder ore bodies without major capital investment.
Is your operation achieving optimal tonnage and recovery rates from your primary grinding circuit? حديث, heavyduty bulk stamp mill for gold mining is engineered to address these exact issues.
2. نظرة عامة على المنتج
The Bulk Stamp Mill is a mechanized, highcapacity gravityimpact crushing and grinding machine designed for the primary reduction of goldbearing quartz rock. It serves as the foundational workhorse in hard rock gold processing plants, تحويل منجم الجريان السطحي (ذاكرة للقراءة فقط) ore into a granular sand for subsequent concentration.
سير العمل التشغيلي:
1. مقدمة الأعلاف: خام ROM (عادة 6" ل 8") is continuously fed via a regulated conveyor or feeder into the mortar box of the stamp mill.
2. Gravity Impact Crushing: Multiple mechanically lifted stamps (وزن 8002,000 رطل لكل منهما) يتم إسقاطها بشكل تسلسلي على طبقة الخام داخل صندوق الملاط, applying direct percussive force.
3. تخفيض حجم الجسيمات: Ore is fractured by repeated impacts. Finer material passes through a perforated steel discharge screen at the mortar box's end, while larger pieces remain for further crushing.
4. تشكيل الطين & تسريح: Crushed material exits as a slurry (when water is introduced) or dry sand, ready for transport to secondary grinding or direct concentration via shaking tables or sluices.
نطاق التطبيق & القيود:
نِطَاق: Ideal for freemilling gold ores where coarse gold liberation is possible at relatively large particle sizes. Best suited for mediumtohigh tonnage operations requiring robust, continuousduty primary crushing.
القيود: Not suitable for ultrafine grinding requirements or highly refractory ores requiring chemical leaching at a very fine size. Performance is optimal with consistent feed size distribution.
