1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Are your gold recovery operations constrained by inefficient primary grinding? Tamaño de alimentación inconsistente, desgaste excesivo del revestimiento, and unplanned maintenance on your comminution equipment directly impact your bottom line. Consider these common challenges in gold ore processing:
Alto costo operativo: Frequent replacement of grinding media and mill liners due to abrasive ore results in significant consumable expenses and production halts.
Tamaño de molienda inconsistente: Variable feed material leads to fluctuating particle size output from your primary mill, reducing downstream cyanidation or gravity recovery efficiency.
Tiempo de inactividad excesivo: Traditional mill designs require lengthy, laborintensive shutdowns for liner changes and maintenance, costing valuable production time.
Ineficiencia energética: Older milling technology may consume excessive power per ton of ore processed, hacer de la energía uno de sus mayores costos incontrolables.
Limitaciones de escalabilidad: Rigid mill configurations struggle to adapt to changing ore body characteristics or increased throughput targets without major capital investment.

¿Su operación busca una solución sólida?, reliable primary grinding solution engineered to reduce cost per ton and maximize gold liberation?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

The China Stamp Mill for gold mining is a modernized, heavyduty mechanized crushing and grinding apparatus designed for the primary comminution of goldbearing quartz rock and ores. It functions as a core piece of mineral processing equipment, applying repetitive percussive force to reduce runofmine (memoria de sólo lectura) ore to a consistent, liberatable size for subsequent concentration processes.

Flujo de trabajo operativo:
1. Introducción al feed: mineral ROM (typically sized below 100mm) is continuously fed into a centralized feed hopper.
2. Percussive Grinding: Una serie de sellos pesados ​​levantados mecánicamente. (pesas) are released in a controlled cycle, dropping onto the ore bed contained within a durable mortar box.
3. Reducción del tamaño de partículas: El impacto repetido fractura el mineral a lo largo de los límites naturales del grano., efficiently liberating gold particles without excessive overgrinding.
4. Descarga de lodo: Ground material is washed through a discharge screen with water, creating a slurry of target particle size that reports to downstream shaking tables, concentradores centrífugos, or leaching circuits.

Ámbito de aplicación & Limitaciones:
Alcance: Ideal for freemilling gold ores where gravity recovery is viable; effective for smalltomedium scale operations (5500 TPD); suitable for remote sites due to robust mechanical design.
Limitaciones: Less efficient on clayrich or highly weathered ores that cause packing; not a finegrinding solution—typically produces product in the 20100 mesh range; requires consistent water supply for slurry handling.

6. ESCENARIOS DE APLICACIÓN

Alluvial/Vein Gold Processing Plant Challenge:

A West African operation processing hard rock quartz veins faced high energy costs and rapid wear from their small ball mill circuit. Downstream gravity recovery was inefficient due to poor and inconsistent primary grind.

Solución:

Implementation of two parallel CSM300 China Stamp Mills as the primary grinding stage ahead of existing shaking tables.

Resultados:

Achieved a target grind of 80%65 mesh consistently. Gravity recovery rate improved from ~55% to over 70%. Combined energy and media savings reduced processing cost by an estimated $18/tonne.

Secondary Grinding Circuit Feed Preparation Challenge:

A South American mine using a cyanidation plant required finer feed but their primary jaw crusher produced too many coarse slabs causing bottlenecks in the secondary roller mill.

Solución:

Installation of a single China Stamp Mill as an intermediate crushing/grinding stage between the jaw crusher and the roller mill.

Resultados:

The stamp mill effectively broke down coarse slabs into granular feed ideal for the roller mill. This balanced the load across the circuit, increasing overall plant throughput by approximately 22%.
