ODM Gold Mining Equipment Sample
1. HAPJE NGA PIKA E DIKIMIT
Are you managing escalating operational costs and unpredictable throughput in your gravity separation circuit? Inconsistent feed density, fluctuating water pressure, and manual adjustments can lead to significant gold losses in your fine recovery operations. These challenges directly impact your bottom line through lost revenue and increased labor for cleanup and retreatment. How do you ensure peak recovery efficiency across every shift without constant supervision? Can your operation maintain high performance with variable feed grades and particle sizes? The solution requires equipment engineered for stability, kontrollin, and maximum mineral capture.
2. PËRMBLEDHJE E PRODUKTIT
The ODM Series Centrifugal Concentrator is a highG force, continuousbatch centrifugal separator designed for the recovery of fine gold and other heavy minerals from slurry. It operates as a critical component in gravity concentration circuits, particularly effective for particles too fine for traditional sluices or jigs.
Rrjedha e punës operative:
1. Prezantimi i ushqimit: A controlled slurry feed is introduced into a rotating drum lined with ribbed riffles.
2. Përqendrimi & Fluidization: Centrifugal force pins heavy particles against the riffles while a continuous fluidization water flow maintains a fluid bed, allowing lighter gangue material to be flushed out.
3. Shkarkimi i vazhdueshëm: Tailings exit the machine continuously through ports at the head of the drum.
4. Mbajtja e koncentratit & Flushing: Gold and heavy concentrates are retained within the riffles. After a set operational cycle, the concentrate is automatically flushed into a secure collection point for further processing.
Fusha e Aplikimit & Kufizimet:
Fushëveprimi: Ideal for primary, scavenger, or cleaner duty in hard rock and alluvial gold operations; effective on sulphide concentrates; suitable for platinum group metals (PGM) and other heavy minerals.
Kufizimet: Performance is dependent on proper particle liberation; not suitable as a primary crusher or for coarse (+2mm) material; requires consistent water supply and pressure.

6. Skenarët e APLIKIMIT
Hard Rock Gold Mine – Scavenger Duty Application
Sfida: A milling circuit was losing significant fine gold to tailings due to inefficient gravity recovery postball mill grind (~ 150 mikron). Existing equipment could not effectively capture liberated particles below 74 mikronë.
Zgjidhje: Installation of two ODM Centrifugal Concentrators in parallel on the combined cyclone underflow stream as a scavenger circuit.
Rezultatet: Monthly gravity gold production increased by 22%. Overall plant recovery improved by an estimated 3%, providing a payback period on equipment of less than six months.
