1. فتحة مدفوعة بنقطة الألم

Are you managing a small to midscale gold operation where consistent, lowcost comminution is critical to profitability? The challenges of processing hard rock gold ore are welldocumented: excessive energy consumption from oversized equipment, high maintenance costs from abrasive materials, and the logistical complexity of operating in remote locations. These factors directly erode your margin. When your primary crushing and grinding circuit is inefficient, you face not only increased power costs but also lost recovery from inadequate liberation. كيف يمكنك تحقيق موثوقة, fine grinding for effective cyanidation or gravity recovery without the capital outlay and operational overhead of a full ball mill circuit? The answer lies in a proven, purposebuilt technology: the modern Custom Stamp Mill.

2. نظرة عامة على المنتج

أ Custom Stamp Mill is a mechanized gravitydriven crushing mill designed specifically for the liberation of freemilling gold from quartz or other host rock. It modernizes the historic stamp battery principle with durable materials and precision engineering for continuous, lowtonnage operation.

سير العمل التشغيلي:
1. يٌطعم: خام الحجم (عادة 2" from a primary jaw crusher) is fed into a enclosed mortar box.
2. سحق & طحن: رفع الطوابع الثقيلة ميكانيكيًا (أحذية) are dropped in sequence onto the ore within the mortar box, pulverizing it by repeated impact.
3. تسريح & تصنيف: Pulverized material passes through a screen at the mortar box discharge, with oversize material recycled and fines reporting to subsequent gold recovery processes (على سبيل المثال, السدود, المكثفات).

نطاق التطبيق & القيود:
مثالية ل: طحن خامات الذهب مجانا, النباتات التجريبية, smallscale commercial operations (150 TPD), historical mine reprocessing, and locations with limited water or power infrastructure.
القيود: Not suitable for refractory ores requiring fine grinding below 100 mesh for liberation, or for hightonnage operations exceeding 75 TPD. Performance is optimal on brittle, siliceous ores.

8.التعليمات

س:What primary crusher feed size is required for an efficient stamp mill operation?
A.For optimal performance,the feed should be reducedto minus two inches(50مم).This is typically achievedwitha small jaw crusher.A correctly sized feed prevents jammingand ensures consistentstamp drop energyis appliedto particle breakage rather than oversized rocks.

س:Cana stamp mill handle wet or clayrich ore?
A.Stamp mills perform beston dryor moderately moist,friable ore.High clay contentcan leadto packingin themortar box reducing efficiency.In such cases,a scrubbingor classification step priorto crushingis recommended.Field data showsaddinga simple trommel screen aheadof themill can resolve this issue.

س:Whatisthe expectedlifespanof keywear components?
A Under normal operation processing quartz ore manganese steel shoes require rotation after approximately500 hoursand replacementafter1500to2000 hoursof operation.Mortarbox dies last significantly longer.This will varybasedon specificore abrasiveness which we can evaluatefrom asample.
