H1: 500 TPH Goudmynwasaanleg: Ontwerp vir HighVolume, HighRecovery Operations

1. PainPoint-gedrewe opening

Skaal alluviale of eluviale goud herstel na 500 TPH presents distinct operational and financial hurdles. Inefficiencies at this scale directly erode profit margins. Staan jy hierdie uitdagings in die gesig?
Deurset-bottelnekke: Conventional scrubbers and sluices cannot maintain consistent feed rates, causing pileups and forcing entire plant slowdowns.
High Clay Content Disruption: Agglomerating clays blind trommel screens and matting, vereis gereelde, costly manual intervention and leading to significant gold loss in the oversize fraction.
Ondoeltreffende boeteverhaling: Fine gold particles (100 gaas) are routinely lost in traditional systems, with industry estimates suggesting losses of 1530% in poorly configured plants.
Oormatige water & Kragvraag: Outdated plant designs consume disproportionate volumes of water and power per ton processed, escalating operational costs and environmental footprint.
Ongeskeduleerde stilstand: Mechanical failures in critical components like bearings, dryf, and pump systems halt production, costing tens of thousands per hour in lost recovery.

The central question for a plant manager is: Hoe kan jy betroubare bereik 500 TPH throughput while maximizing recovery yield and controlling operational expenses?

2. Produk Oorsig

Hierdie 500 TPH Gold Mining Washing Plant is 'n volledige, modular processing system designed for the continuous scrubbing, vertoning, klassifikasie, and concentration of placer gold deposits. It is engineered to handle challenging material with high clay content and a broad particle size distribution.

Operasionele werkvloei:
1. Primêre skrop & Sifting: Feed material is aggressively scrubbed in a robust trommel or scrubber barrel to break down clays and conglomerates, then screened to remove oversize waste (+75mm).
2. Misverspreiding & Klassifikasie: The undersize slurry is evenly distributed to a bank of primary concentrators (bv., jigs or spirals) via a calibrated feed system. A hydrocyclone cluster may separate sands from slimes for targeted processing.
3. Primêre konsentrasie: Coarse and medium gold is recovered in the primary gravity circuit.
4. Fines Recovery Enhancement: Tailings from the primary circuit are routed through specialized fine gold recovery units (bv., sentrifugale konsentrators) to capture sub100 mesh particles.
5. Uitskotbestuur & Waterhantering: A dewatering screen system recovers process water for recirculation, while compacted tailings are conveyed for stacking.

Toepassingsomvang & Beperkings:
Omvang: Ideaal vir grootskaalse alluviale (riverine), eluviale (colluvial), and weathered deposit operations. Effective on a range of materials from sandy gravels to sticky clays.
Beperkings: Nie geskik vir harde rock nie (laai) ore processing without prior crushing. Prestasie is afhanklik van behoorlike voergrootteverspreiding (<200mm aanbeveel) and consistent feed rate control.
