1. فتحة مدفوعة بنقطة الألم

Is your gold recovery operation constrained by persistent bottlenecks and escalating costs? لمديري المصانع والمقاولين الهندسيين, the crushing and grinding circuit is often the source of critical inefficiencies that directly impact the bottom line. تشمل التحديات الشائعة مع معدات التفتيت التقليدية ما يلي::

التوقف المفرط للصيانة: Frequent liner changes and unplanned repairs on critical components halt production, تكلف الآلاف في الساعة من الإنتاجية المفقودة.
توزيع غير متناسق لحجم الجسيمات: Poorly calibrated or worn equipment yields uneven ore feed to concentration processes, خفض معدلات استرداد الذهب بشكل عام.
استهلاك عالي للطاقة لكل طن: Older stamp mill designs and inefficient drives lead to unsustainable power costs, النفقات التشغيلية الأولية.
عملية كثيفة العمالة & يراقب: Reliance on manual adjustments and sampling increases labor costs and introduces human error, affecting process stability.
قيود قابلية التوسع: Difficulty in efficiently scaling operations to process highergrade zones or increased ore volumes without major capital redesign.

Are you seeking a robust solution that enhances throughput predictability, reduces total operating cost per ton, and delivers consistent grind for optimal cyanidation or gravity recovery? The evolution of the modern stamp mill addresses these exact operational challenges.

2. نظرة عامة على المنتج: HeavyDuty Gravity Discharge Stamp Mill

This product is a modern, industrialgrade stamp mill engineered for the continuous crushing and fine grinding of goldbearing ore. It is designed as a core component within a hard rock gold processing plant, typically following primary jaw crushing.

سير العمل التشغيلي:
1. مقدمة الأعلاف: خام الحجم (عادة 2") is fed uniformly into the mortar box via a regulated feed system.
2. GravityPowered Percussion: سلسلة من الطوابع الثقيلة التي يتم رفعها ميكانيكيًا (أحذية) are released to drop onto the ore bed within the mortar box, applying repeated impact force.
3. تخفيض حجم الجسيمات: Ore is fractured by direct impact and ground via attrition between particles beneath the stamp shoe.
4. تفريغ الطين: Finely ground material is washed through a perforated screen plate at the mortar box end by a continuous water flow, creating a slurry for subsequent concentration stages.

نطاق التطبيق & القيود:
نِطَاق: Ideal for freemilling gold ores where liberation occurs at relatively coarse grinds. Highly effective in remote operations due to mechanical simplicity and reliability. Suited for both smallscale commercial mining and larger modular plant configurations.
القيود: Not optimal for ultrafine grinding requirements (<100 شبكة) or highly abrasive, lowgrade deposits where wear costs may be prohibitive. Requires a consistent feed size and controlled water volume for optimal operation.
