1. PYNPUNT GEDREWE OPENING

Die bestuur van 'n goudverwerkingsoperasie vereis balansering van deurset, herstelkoerse, en bedryfskoste. When your stamp mill is a bottleneck or a compliance liability, profitability erodes. Staan jy hierdie spesifieke uitdagings in die gesig?

Regulerende afsluitingsrisiko: Noncompliant equipment containing restricted substances (bv., lei, kadmium, seswaardige chroom) can lead to fines, export rejections, and costly site remediation, directly impacting your market access and bottom line.
Hoë instandhoudingstyd: Conventional stamp mills with nonspecialized alloys in wear parts require frequent stoppages for replacement of dies, skoene, en voerings. This unplanned downtime cuts into crushing capacity and increases labor costs.
Inefficient Particle Liberation: Inconsistent stamp impact and poor discharge control can result in overcrushing (generating excessive slimes) or undercrushing (locking gold in larger particles), reducing overall recovery efficiency in downstream processes like leaching or gravity separation.
Oormatige energieverbruik: Ouer, mechanically inefficient designs with poor power transmission draw more kWh per ton of ore processed, making energy a disproportionately high operational cost.

Die sentrale vraag vir aanlegbestuurders is: hoe kan jy betroubare bereik, highvolume ore crushing while ensuring global export compliance and controlling longterm operating expenses?

2. PRODUK OORSIG

The Rohs Compliant Stamp Mill is a modern reinterpretation of the traditional gravitydriven crushing machine, engineered for commercialscale gold ore processing. It is designed specifically for operations that require verified compliance with the Restriction of Hazardous Substances (Rohs) directive for export markets.

Operasionele werkvloei:
1. Voer & Beheer: Runofmine or primarycrushed ore is fed into a regulated feed hopper, ensuring a consistent charge to the mortar box.
2. Gravity Crushing: Mechanically lifted stamps are released to freefall onto the ore bed within a hardened mortar box. The kinetic energy fractures the rock.
3. Klassifikasie & Ontslag: Crushed material passes through a grated screen at the mortar box discharge. Groot materiaal bly oor vir verdere impak, while liberated material flows to downstream concentration.

Toepassingsomvang & Beperkings:
Omvang: Ideal for freemilling gold ores and sulphide ores requiring preleach size reduction. Effective in standalone operations or as a secondary crusher in a larger circuit. Suited for regions with stable power infrastructure or compatible with hybrid dieselpower systems.
Beperkings: Nie geskik vir nat nie, clayrich ores without prior scrubbing. Requires foundational concrete footing due to dynamic loads. Particle size output is typically 20 gaas; finer grinding requires additional ball milling.
