1. PYNPUNT GEDREWE OPENING

Are you managing a gold processing operation where inconsistent ore feed, oormatige stilstand vir voering veranderinge, and rising energy costs are eroding your profit margins? Each hour your primary grinding circuit is offline for maintenance represents a direct loss in throughput and revenue. The challenge of achieving consistent, fine liberation of goldbearing minerals without incurring prohibitive operational expenses is a constant pressure.

Oorweeg hierdie algemene operasionele struikelblokke:
Hoë instandhoudingstyd: Frequent shutdowns to replace worn stamp mill shoes, sterf, and liners disrupt continuous processing schedules.
Ondoeltreffende energiegebruik: Older or poorly calibrated stamp mills consume disproportionate power per ton of ore crushed, bedryfskoste direk beïnvloed.
Inkonsekwente produkgrootte: Variable feed size or wear on components leads to unevenly crushed material, compromising downstream recovery in cyanidation or gravity circuits.
Hoë Arbeid & Veiligheidskoste: Manual monitoring and mechanical adjustments increase labor overhead and potential safety exposure around heavy moving parts.
Skaalbaarheidsbeperkings: Inflexible designs struggle to adapt to varying ore hardness or increased plant capacity targets.

What if your primary crushing stage could deliver more reliable performance with predictable maintenance intervals and lower cost per ton? Die oplossing lê in gemoderniseer, precisionengineered stamp mill technology.

2. PRODUK OORSIG

The ODM Stamp Mill is a modern reinterpretation of the proven camandlever crushing principle, engineered for reliable primary crushing of goldbearing quartz ores. Dit is ontwerp as 'n robuuste, lowspeed impact crusher where mechanically lifted heavy stamps (hamers) are dropped onto ore fed into a mortar box, die materiaal te breek deur herhaalde impak.

Operasionele werkvloei:
1. Voer Inleiding: Runofmyne (ROM) ore is consistently fed into the stamp mill’s mortar box via a regulated feeder.
2. Cyclic Crushing: The rotating camshaft lifts multiple cast iron or steel stamps in sequence, releasing them to fall under gravity onto the ore.
3. Deeltjiereduksie: Ore is fractured by direct impact and grinding between the stamp shoe and the die (mortar box base).
4. Misafvoer: Crushed material exits through a screen grate at the front of the mortar box, met water gemeng om 'n flodder te vorm vir vervoer na sekondêre verwerking.

Toepassingsomvang & Beperkings:
Ideaal vir: Freemilling gold ores where coarse gold liberation is required; klein tot medium skaal bedrywighede (1100 TPD); regions with stable but limited power availability; operations prioritizing mechanical simplicity and durability.
Beperkings: Nie geskik vir nat nie, sticky clay ores that cause packing; minder energiedoeltreffend as sommige moderne balmeulens vir fyn maal; requires firm foundation due to dynamic loads.
