1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Are your gold recovery operations hampered by inconsistent throughput, excessive downtime for liner replacement, and unpredictable maintenance costs? Los equipos tradicionales de trituración y molienda a menudo no cumplen con las demandas de los modernos., procesamiento de mineral de alto volumen, leading to significant financial drain. Considere estos desafíos comunes:
Tiempo de inactividad no planificado: Frequent breakdowns and the laborintensive process of replacing worn stamper shoes or dies halt your entire milling circuit.
Liberación ineficiente: Inconsistent particle size distribution from the stamping process can lock fine gold within larger ore fragments, reducir las tasas generales de recuperación.
Altos costos operativos: Consumo excesivo de energía por tonelada de mineral procesado, coupled with high wear part consumption, erosiona los márgenes de beneficio.
Limitaciones de escalabilidad: Older stamp mill designs struggle to integrate with modern cyanidation or gravity concentration circuits, creating bottlenecks.

How do you increase throughput reliability while controlling the total cost of ownership for your primary crushing and grinding stage? The solution requires a reengineered approach to a proven technology.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

The modern heavyduty stamp mill is a mechanized crushing system designed for the reliable reduction of goldbearing quartz ore. It functions as a primary crusher and grinder, delivering a consistent feed for secondary concentration processes.

Flujo de trabajo operativo:
1. Introducción al feed: Runofmine ore is fed into a robust mortar box via a regulated feed system.
2. Mechanical Stamping: Una serie de sellos pesados ​​levantados mecánicamente. (martillos) are released in sequence, dropping onto the ore bed within the mortar box.
3. Reducción de mineral: The impact and weight of the stamps crush and pulverize the quartz matrix, liberating gold particles.
4. Descarga de lodo: El material triturado se lava a través de una rejilla de descarga con agua., creating a slurry that reports to downstream gravity separation or leaching circuits.

Ámbito de aplicación & Limitaciones:
Alcance: Ideal for freemilling gold ores where the gold is liberated at coarse to medium grind sizes. Highly effective in remote operations due to mechanical simplicity and durability. Suited for both stationary plant installations and modular mining camps.
Limitaciones: Less efficient for ultrafine grinding requirements compared to ball mills. Not optimal for complex refractory ores requiring finer liberation. Requires a consistent feed size to maintain optimal operation.
