1. فتحة مدفوعة بنقطة الألم

Are you facing persistent bottlenecks in your gold recovery circuit due to inconsistent ore liberation? Operational challenges with traditional crushing and grinding methods directly impact your bottom line. ضع في اعتبارك نقاط الألم الشائعة هذه:
معدلات استرداد منخفضة & High Tailings: Inefficient particle size reduction leaves gold locked within host rock, leading to recoveries below target and valuable material lost to tailings dams.
التوقف المفرط & صيانة: تغييرات متكررة في الخطوط الملاحية المنتظمة, تحمل الفشل, and unplanned stoppages in your comminution process halt production and inflate maintenance labor and parts costs.
استهلاك عالي للطاقة لكل طن: أقدم, inefficient milling technology consumes disproportionate power for the grind achieved, making energy one of your largest uncontrollable operational expenses.
حجم الطحن غير متناسق: Variable feed characteristics lead to an unstable product size, overworking downstream concentration equipment like cyanidation tanks or gravity circuits and reducing their efficiency.

هل العملية الخاصة بك تسعى قوية, proven solution to enhance liberation, reduce operating costs, and stabilize your milling circuit? The industrial Chinese Stamp Mill represents a timetested engineering approach refined for modern mineral processing demands.

2. نظرة عامة على المنتج

The industrial Chinese Stamp Mill is a gravitydriven, mechanical crushing and grinding mill designed for the selective liberation of freemilling gold from quartz and other host rocks. Its core function is to repeatedly crush ore via heavy, mechanically lifted stamps, facilitating efficient gold recovery through subsequent gravity separation or leaching processes.

سير العمل التشغيلي:
1. مقدمة الأعلاف: RunofMine (ذاكرة للقراءة فقط) ore or primarily crushed feed is uniformly introduced into the mortar box.
2. Cyclic Percussive Grinding: Mechanically powered stamps (48 لكل مطحنة) are lifted and dropped in a controlled cycle onto the ore bed within the mortar box.
3. تشكيل الطين & تسريح: Water is introduced concurrently, خلق الطين. Finely crushed material passes through a perforated discharge screen at the mortar box's front.
4. Concentration Ready Output: الطين المفرغ, with optimally liberated gold particles, is directed to shaking tables, السدود, or directly to leaching for final recovery.

نطاق التطبيق & القيود:
مثالية ل: طحن خامات الذهب مجانا, اختبار المصنع التجريبي, عمليات التعدين الصغيرة والمتوسطة الحجم (5500 TPD), and regions with limited grid power availability.
القيود: Less effective for refractory ores requiring ultrafine grinding (<100 شبكة) أو تمعدن الكبريتيد المعقد. Primary crushing to a manageable size (عادة <2") is required ahead of the stamp mill.
