1. PYNPUNT GEDREWE OPENING

Staar jy voor aanhoudende knelpunte in jou goudherwinningsbaan? Inefficient primary crushing and grinding directly impact throughput, herstelkoerse, en bedryfskoste. Common challenges with traditional comminution equipment include:

Hoë operasionele stilstand: Frequent liner changes and unplanned maintenance on primary crushers halt your entire milling circuit, duisende per uur in verlore produksie kos.
Inkonsekwente vermindering van voergrootte: Variable ore hardness leads to uneven particle size distribution from primary crushing, overloading your ball mills and reducing overall grinding efficiency.
Oormatige energieverbruik: Inefficient size reduction processes can consume over 50% of your site's power budget, with a significant portion wasted as heat and vibration rather than productive fracturing.
Hoë slytasie-onderdeelkoste: The abrasive nature of goldquartz ore leads to accelerated wear on hammers, voerings, en sterf, driving up your cost per ton for consumables.
Beperkte skaalbaarheid & Buigsaamheid: Fixedconfiguration crushers struggle to adapt to changing ore body characteristics or increased throughput demands without major capital expenditure.

Is your operation sacrificing gold recovery due to inadequate primary size reduction? What if you could transform this bottleneck into a controlled, highefficiency process that elevates the performance of your entire processing plant?

2. PRODUK OORSIG: HEAVYDUTY STAMP MILL FOR GOLD ORE PROCESSING

This heavyduty stamp mill is engineered as a robust primary crushing solution specifically for freemilling gold ores. Dit is ontwerp om runofmine te aanvaar (ROM) material and deliver a consistent, coarse sand product ideal for secondary grinding via ball mills or direct leaching feed.

Operasionele werkvloei:
1. Voerinname: ROM erts (tot gespesifiseerde voergrootte) is delivered via conveyor or feed hopper into the stamp mill's mortar box.
2. Meganiese perkussie: 'N reeks meganies opgehef, heavy weighted stamps (skoene) are sequentially dropped onto the ore bed within the mortar box.
3. Grootte verkleining & Bevryding: The repeated impact fractures the quartz matrix, liberating coarse gold particles while reducing the ore to a target size of approximately 10 gaas aan 20 gaas.
4. Misafvoer: Crushed material is continuously discharged with wash water as a slurry through a grated screen at the mortar box end, gereed vir verdere verwerking.

Toepassingsomvang & Beperkings:
Ideaal vir: Vrymeulende gouderts, loodsaanlegbedrywighede, smalltomedium scale mining projects (150 TPH), and operations prioritizing mechanical simplicity and ease of maintenance.
Beperkings: Not suitable for refractory ores requiring fine grinding for liberation. Efficiency decreases with high clay content or excessively wet feed. Requires a consistent mechanical power source.
