1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Managing a gold mining operation means confronting persistent challenges that directly erode profitability. When it comes to material handling and processing, Los puntos débiles comunes incluyen:
Alto tiempo de inactividad debido a bloqueos: Unprocessed oversize material and claybound aggregates can halt entire processing circuits, costando miles por hora en producción perdida.
Inefficient Liberation of Gold: Inadequate scrubbing and breaking of ore leads to poor gold exposure, resulting in significant recoverable gold reporting to tailings.
Agua excesiva & Consumo de energía: Inefficient washing and screening processes inflate operational costs for water procurement, bombeo, and treatment.
Alta carga de mantenimiento: Equipment not designed for abrasive feed materials suffers rapid wear on critical components, leading to frequent shutdowns and high parts replacement costs.
Alimentación inconsistente a los procesos posteriores: Variable particle size distribution from primary processing creates instability in milling and gravity circuits, reduciendo la eficiencia general de recuperación.

Are you seeking a solution to reduce circuit downtime, improve gold liberation rates, and lower your cost per ton processed?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO: SCRUBBER / TROMMEL FOR GOLD BEARING ALLUVIAL & HARD ROCK ORE

A heavyduty scrubber or trommel is a core piece of premilling equipment designed for the aggressive preparation of goldbearing ore. Its function is to break down claybound aggregates, scrub deleterious materials from rock surfaces, and classify material by size to prepare an optimal feed for downstream concentration.

Flujo de trabajo operativo:
1. Introducción al feed: Runofmine (memoria de sólo lectura) or alluvial ore is conveyed into the rotating drum section.
2. Fregado agresivo & Desgaste: Internal lifters cascade the material; the impact between rock particles and against reinforced scrubber bars breaks down clays and soft aggregates.
3. Apresto & Clasificación: A medida que el material viaja a través del tambor, El material de tamaño insuficiente pasa a través de las aberturas de la pantalla. (trommel) or grates (depurador).
4. Separación de productos: Demasiado grande (+10mm to +50mm, depending on screen selection) exits the drum discharge end for further crushing. The undersize slurry reports to vibrating screens or direct pump sumps for subsequent gold recovery processes.

Ámbito de aplicación: Ideal for alluvial/eluvial deposits with sticky clays, weathered saprolite ore, and hard rock ores requiring prewashing and classification before cyanidation or gravity circuits.

Limitaciones: Not a substitute for primary crushing of competent hard rock; feed size must be compatible with drum diameter. Water availability is a prerequisite for effective operation.
