Chinese Stamp Mill Gold Mining Design Service
1. PAINPOINT driven اوپننگ
ڇا توهان پنهنجي سون جي بحالي واري سرڪٽ ۾ مسلسل رڪاوٽن کي منهن ڏئي رهيا آهيو? Inefficient primary grinding and liberation can directly undermine your entire operation's profitability. Common challenges with conventional crushing and grinding setups include:
اعلي آپريشنل Downtime: Frequent liner changes and unplanned maintenance in primary crushers and ball mills halt your processing line, گم ٿيل پيداوار ۾ هزارين في ڪلاڪ خرچ.
SubOptimal گولڊ لبريشن: Inconsistent particle size from primary grinding limits cyanide leach or gravity recovery efficiency, leaving payable gold locked in tailings.
اضافي توانائي واپرائڻ: Overgrinding to achieve target liberation consumes disproportionate power, one of the highest cost centers in mineral processing.
High Media & Liner Wear Costs: Abrasive ore types lead to accelerated consumption of grinding media and mill liners, driving up consumable expenses.
Complexity in Wet Ore Processing: Handling clayrich or highmoisture feed material can lead to clogging, گھٽتائي ذريعي, and increased handling costs.
Is your current primary comminution circuit a source of variable performance and unpredictable cost? What if a robust, purposebuilt solution could provide consistent, coarse liberation with lower operational complexity?
2. پيداوار جو جائزو
The Chinese Stamp Mill is a modern reinterpretation of a historically proven principle for coarse gold ore liberation. This gravityimpact crushing equipment is engineered for primary or secondary reduction of goldbearing quartz rock and sulphide ores.
آپريشنل ڪم فلو:
1. فيڊ جو تعارف: رنوفمين (روم) ore is fed into a sturdy mortar box.
2. ڪشش ثقل تي هلندڙ اثر: مشيني طور تي ڳري اسٽيمپون کڻڻ (وزن) are released to drop onto the ore bed.
3. Continuous Pulverization: The repeated impact of multiple stamps reduces the ore to a coarse sand consistency.
4. WaterAssisted Discharge: A controlled flow of water flushes the crushed material through a perforated screen plate for classification.
5. Gravity Concentration Ready Output: The discharged slurry presents optimally liberated coarse gold particles for immediate recovery via downstream concentrators (مثال, ڇڪڻ واري ٽيبل, centrifugal concentrators).
ايپليڪيشن جو دائرو & حدون:
لاء مثالي: Small to mediumscale hard rock gold operations, پائلٽ ٻوٽا, هنرمند & smallscale mining (اي ايس ايم) رسمي منصوبا, and processing centers dealing with freemilling ores.
لاءِ مناسب: Remote sites with limited grid power or where operational simplicity is paramount.
حدون: Not designed for fine grinding to ultrafine sizes (<100 ميش). Efficiency decreases with highly ductile or claybound ores without feed preparation.
