1. PEMBUKAAN PAINPOINT DRIVEN

Managing a gold processing operation means balancing throughput with recovery in a highstakes environment. Inefficient or unreliable equipment directly impacts your bottom line. Adakah anda menghadapi cabaran berterusan ini?
Suboptimal Recovery Rates: Inconsistent particle size liberation and poor separation efficiency can leave valuable micron gold in your tailings, representing a direct revenue loss.
Masa Henti Berlebihan untuk Penyelenggaraan: Kehausan komponen yang kerap, especially from abrasive ore, halts production. Industry data indicates unplanned maintenance can cost over $1,500 per hour in lost processing capacity.
Kos Operasi yang Tinggi: Penggunaan kuasa yang tidak cekap, excessive reagent use due to poor process control, and the labor required for constant monitoring and adjustment erode profit margins.
Alam sekitar & Risiko Pematuhan Keselamatan: Leaks, spills, or inadequate containment from equipment failure pose significant regulatory and liability concerns.

Persoalan utama untuk pengurus loji ialah: how can you enhance gold recovery consistency while reducing total operational costs and unplanned downtime? The answer lies in specifying highperformance, durable equipment engineered for the specific demands of gold extraction.

2. GAMBARAN KESELURUHAN PRODUK: HighCapacity Centrifugal Gold Concentrators

A centrifugal gold concentrator is a enhanced gravity separation device designed to recover fine gold that traditional methods like sluices or jigs often miss. It accelerates the gravitational force on feed material to separate highdensity gold particles from lowerdensity gangue.

Aliran Kerja Operasi:
1. Slurry Feed: Ore slurry, typically classified to under 2mm, is continuously fed into the rotating bowl of the concentrator.
2. Centrifugal Separation: As the bowl spins at high RPM, centrifugal forces up to 200 Gs push material against the bowl wall. Heavier gold particles penetrate and are trapped in a series of riffles or grooves.
3. Continuous Concentration: Lighter waste material fluidizes and flows over the riffles, exiting as tailings.
4. Automated Discharge: After a set cycle time, the concentrate bowl slows, and an automated rinse cycle discharges the enriched gold concentrate into a collection point for further refining.

Skop Permohonan & Batasan:
Sesuai Untuk: Recovering free gold (particularly fine flour gold), as a primary concentrator for alluvial deposits, or as a secondary scavenger unit on hard rock mill discharge.
Batasan: Less effective on coated or tarnished gold particles without pretreatment. Performance is dependent on proper feed size classification and consistent slurry density.
