1. فتحة مدفوعة بنقطة الألم

Are your gold processing operations constrained by unreliable or inefficient primary crushing? تحدد مرحلة تقليل الحجم الأولية نغمة دائرة التعافي بأكملها. Common challenges with suboptimal معدات سحق خام الذهب يشمل:
التوقف المفرط: تغييرات متكررة في الخطوط الملاحية المنتظمة, الصيانة غير المخطط لها, and component failures halt your milling circuit, تكلف الآلاف في الساعة من الإنتاج المفقود.
Low Throughput of HighGrade Ore: Inefficient crushing creates bottlenecks, preventing your plant from processing more valuable material and maximizing revenue during peak price cycles.
Poor Particle Size Distribution: Inconsistent product size increases load on grinding mills, elevating specific energy consumption (كيلووات ساعة/طن) and wearing mill liners prematurely.
تكاليف تشغيلية عالية: Skyrocketing energy consumption, coupled with frequent replacement of wear parts under abrasive conditions, يؤدي إلى تآكل هوامش الربح.
Difficulty with Variable Ore Hardness: A single blast can produce a mix of soft oxide and hard sulfide material, challenging crushers not built for such fluctuation.

Is your current setup causing unpredictable downtime and limiting your plant’s potential? What if your primary crusher could deliver consistent fragmentation, reduce energy costs per ton, and improve overall circuit availability?

2. نظرة عامة على المنتج

This product line focuses on robust, stationary primary jaw crushers engineered specifically for the demanding first stage of gold ore crushing. مصممة لقبول runofmine (ذاكرة للقراءة فقط) feed directly from haul trucks, these machines provide the reliable, highcapacity reduction required for optimal downstream cyanidation or gravity recovery.

سير العمل التشغيلي:
1. خام ROM (ما يصل إلى 1200 ملم) is dumped directly into the crusher’s vibrating grizzly feeder (فجفف فجفف).
2. The VGF removes fines and directs oversize material into the deep crushing chamber of the jaw crusher.
3. A highinertia flywheel and optimized kinematics ensure a powerful compressive force to break even the most stubborn quartz veins or sulfide bands.
4. Crushed product is discharged at a consistent, adjustable CSS (إعداد الجانب المغلق), typically between 150200mm, ready for secondary crushing or conveyor transport.

نطاق التطبيق: مثالية لخامات الذهب الصخور الصلبة (ودائع العقد), including quartzite, greenstone belts, and sulfidic ores. Suitable for both greenfield installations and retrofit projects aiming to debottleneck existing circuits.

القيود: غير مصممة للرطب, sticky placer or alluvial material without significant feed system modification. Primary jaw crushers are a fixed installation; mobile solutions are configured differently.
