1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Managing a gold processing operation means balancing throughput with recovery in a highstakes environment. Los equipos ineficientes o poco confiables impactan directamente sus resultados. ¿Estás enfrentando estos desafíos persistentes??
Suboptimal Recovery Rates: Inconsistent particle size liberation and poor separation efficiency can leave valuable micron gold in your tailings, representando una pérdida directa de ingresos.
Tiempo de inactividad excesivo para mantenimiento: Desgaste frecuente de componentes, especially from abrasive ore, halts production. Industry data indicates unplanned maintenance can cost over $1,500 per hour in lost processing capacity.
Altos costos operativos: Consumo de energía ineficiente, excessive reagent use due to poor process control, and the labor required for constant monitoring and adjustment erode profit margins.
Ambiental & Riesgos de cumplimiento de seguridad: Leaks, spills, or inadequate containment from equipment failure pose significant regulatory and liability concerns.

La pregunta central para los gerentes de planta es: 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. DESCRIPCIÓN GENERAL DEL PRODUCTO: 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.

Flujo de trabajo operativo:
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. Concentración continua: Lighter waste material fluidizes and flows over the riffles, exiting as tailings.
4. Descarga automatizada: 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.

Ámbito de aplicación & Limitaciones:
Ideal para: 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.
Limitaciones: Less effective on coated or tarnished gold particles without pretreatment. Performance is dependent on proper feed size classification and consistent slurry density.
