1. فتحة مدفوعة بنقطة الألم

هل تدير عمليات استرداد الذهب المثقلة بالإنتاجية غير المتسقة؟, التوقف المفرط للصيانة, and unpredictable operating costs? Key challenges in primary ore crushing and liberation often include:

ارتفاع وقت التوقف التشغيلي: Frequent liner changes and mechanical failures in crushing circuits halt your entire processing line, تكلف الآلاف في الساعة من الإنتاج المفقود.
تحرير الذهب غير فعال: Inconsistent particle size from primary crushers leads to poor contact in subsequent leaching or gravity circuits, directly reducing overall recovery rates.
الاستهلاك المفرط للطاقة: Older crushing technologies consume disproportionate power per ton of ore processed, تآكل هوامش الربح.
ارتفاع تكاليف عمالة الصيانة: معقد, laborintensive maintenance routines for legacy stamp mills or jaw crushers increase your total cost of ownership and safety exposure.
قيود قابلية التوسع: Inflexible equipment that cannot adapt to varying ore hardness or feed grades creates bottlenecks in expanding operations.

2. نظرة عامة على المنتج

The modern heavyduty stamp mill is a mechanized percussion crushing system engineered for the primary liberation of gold from quartz and hard rock ore. It is designed as a reliable, highimpact workhorse for mediumtohigh volume operations where consistent sub10mm output is critical for optimal downstream cyanidation or gravity recovery.

سير العمل التشغيلي:
1. مقدمة الأعلاف: Runofmine (ذاكرة للقراءة فقط) ore is fed into a robust steel mortar box.
2. الإيقاع الميكانيكي: Powered camshafts lift and release a series of weighted stamps (5002000كجم لكل منهما), تسليم تسيطر عليها, highimpact blows onto the ore bed.
3. التخفيض التدريجي: Ore is crushed through repeated impact against hardened die plates within the mortar box.
4. تفريغ الطين: Finely crushed material exits through a discharge screen at the mortar box perimeter, mixed with water to form a slurry ready for secondary processing.

نطاق التطبيق & القيود:
مثالية ل: خامات الذهب الصخور الصلبة (عروق الكوارتز), النباتات التجريبية, operations prioritizing mechanical simplicity and high uptime over ultrafine grinding.
القيود: غير مناسب للناعمة, خامات الطين التي تسبب التعبئة; يتطلب حجم تغذية ثابتًا (عادة <100مم); operates most efficiently within defined moisture content parameters.
