1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Are you managing a gold processing operation where throughput, tasas de recuperación, and operational costs are under constant pressure? The performance of your comminution circuit directly impacts your bottom line. Los desafíos comunes con las operaciones de las fábricas de sellos convencionales incluyen:
Tiempo de inactividad excesivo para mantenimiento: Cambios frecuentes de revestimiento, desgaste del árbol de levas, and mortar box repairs lead to significant production halts.
Molienda inconsistente & Pobre liberación: Uneven particle size distribution from worn stamps or irregular feed can trap valuable gold within larger ore particles, reducing overall recovery in downstream processes like cyanidation or gravity concentration.
Altos costos operativos: Significant energy consumption per ton of ore processed, junto con altos requisitos de mano de obra para la alimentación manual y el monitoreo, erosiona los márgenes de beneficio.
Limitaciones de escalabilidad: Traditional designs often struggle with efficient throughput increases without major footprint expansion or duplicate mill installations.

How do you increase tonnage and improve gold liberation while controlling maintenance overhead and energy use? The solution requires a modernized approach to a proven technology.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

Our White Label Stamp Mill is a modernized, heavyduty gravitydriven crushing mill engineered for the reliable comminution of goldbearing ores. It is designed as a core component for small to midscale processing plants, pilot operations, and heritage sites requiring robust, understandable technology.

Flujo de trabajo operativo:
1. Alimentación controlada: Ore is consistently fed via a regulated conveyor or feeder into the mortar box.
2. Trituración impulsada por gravedad: Los sellos levantados mecánicamente se sueltan para caer sobre el mineral., utilizing kinetic energy for fracture.
3. Descarga continua: Crushed material passes through a perforated screen plate at the mortar box end, asegurando un tamaño de producto controlado.
4. Transporte de lodos: The discharged pulp is typically directed to gravity concentration tables or a leaching circuit for gold recovery.

Ámbito de aplicación & Limitaciones:
Ideal para: Molienda libre de minerales de oro, material de veta de cuarzo, pruebas en planta piloto, and operations in regions with limited access to complex technical support or unstable power grids.
Más adecuado para: Smalltomedium scale operations processing 50500 toneladas por día.
Limitaciones: No es óptimo para trabajos muy duros., minerales abrasivos (p.ej., sulfuros) without significant wear considerations. Requiere un tamaño de alimentación consistente (típicamente 2" alimentar) para un funcionamiento óptimo.

Solución:

Implementation of two parallel White Label Stamp Mills configured with finer discharge screens paired directly with optimized shaking tables.

Resultados:

A more uniform grind size resulted in measurable improvements within one month of commissioning:
Gravity recovery rate increased by approximately 18%.
Overall plant throughput rose by an estimated due to reduced blockages downstream.
Maintenance shifts were reallocated from constant mill repair to proactive plant optimization.

Heritage Site & Demonstration Plant Challenge:
