1. PYNPUNT GEDREWE OPENING

Word jou goudherwinningsbedrywighede beperk deur ondoeltreffende primêre vergruising en maal? Verouderde seëlmeulens en ondermaatse toerusting skep aanhoudende knelpunte wat 'n direkte impak op jou wins het. Oorweeg hierdie algemene uitdagings:
Hoë bedryfskoste: Oormatige energieverbruik per ton erts verwerk en gereeld, unplanned maintenance on worn stamps and dies drain profitability.
Inkonsekwente deurset & Herstel: Variable feed size and manual adjustments lead to uneven particle liberation, causing valuable gold to be locked in oversized material or lost as fines.
Oormatige stilstand: Lang, laborintensive die replacement and alignment procedures halt your entire milling circuit, costing thousands in lost production per hour.
Skaalbaarheidsbeperkings: Older stamp mill designs cannot easily adapt to increased ore volume or harder ore bodies without major capital investment.

Is your operation achieving optimal tonnage and recovery rates from your primary grinding circuit? 'n moderne, heavyduty bulk stamp mill for gold mining is engineered to address these exact issues.

2. PRODUK OORSIG

The Bulk Stamp Mill is a mechanized, highcapacity gravityimpact crushing and grinding machine designed for the primary reduction of goldbearing quartz rock. It serves as the foundational workhorse in hard rock gold processing plants, transforming runofmine (ROM) ore into a granular sand for subsequent concentration.

Operasionele werkvloei:
1. Voer Inleiding: ROM erts (tipies 6" aan 8") is continuously fed via a regulated conveyor or feeder into the mortar box of the stamp mill.
2. Gravity Impact Crushing: Multiple mechanically lifted stamps (weeg 8002,000 lbs elk) are sequentially dropped onto the ore bed within the mortar box, applying direct percussive force.
3. Deeltjiegroottevermindering: Ore is fractured by repeated impacts. Finer material passes through a perforated steel discharge screen at the mortar box's end, while larger pieces remain for further crushing.
4. Misvorming & Ontslag: Crushed material exits as a slurry (when water is introduced) or dry sand, ready for transport to secondary grinding or direct concentration via shaking tables or sluices.

Toepassingsomvang & Beperkings:
Omvang: Ideal for freemilling gold ores where coarse gold liberation is possible at relatively large particle sizes. Best suited for mediumtohigh tonnage operations requiring robust, continuousduty primary crushing.
Beperkings: Not suitable for ultrafine grinding requirements or highly refractory ores requiring chemical leaching at a very fine size. Performance is optimal with consistent feed size distribution.

6. TOEPASSINGSSCENARIO'S

MidTier Gold Mine Expansion Project
