1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

La gestión de una operación de procesamiento de oro requiere equilibrar el rendimiento, tasas de recuperación, y costos operativos. When your stamp mill is a critical component, outdated or noncompliant equipment creates significant bottlenecks. ¿Estás enfrentando:
Regulatory Shutdown Risk: Using components containing restricted substances (p.ej., dirigir, cadmium, mercury in alloys, electrical parts) can halt operations in regulated markets, leading to costly fines and import/export delays.
Inefficient Particle Size Reduction: Inconsistent stamp impact and wear on shoes/dies results in poor liberation of gold from ore, directly capping your maximum recovery rate and wasting valuable material.
Excessive Maintenance Downtime: Frequent breakdowns from nonspecialized components demand constant mechanical attention, pulling crews from other critical tasks and reducing overall plant availability.
Altos costos operativos: Unoptimized power consumption per ton of ore crushed and the recurring expense of replacing nondurable parts erode profit margins.

La pregunta central para los gerentes de planta es: ¿Cómo puedes lograr confiabilidad?, compliant comminution without sacrificing throughput or escalating maintenance overhead?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

This product line comprises a modern Rohs Compliant Stamp Mill engineered for gold ore processing. Designed for commercial mining operations and pilot plants, it delivers the proven mechanical crushing action of traditional stamps while meeting stringent international environmental and safety directives.

Flujo de trabajo operativo:
1. Introducción al feed: Sized ore is fed uniformly into the mortar box via a regulated feed system.
2. Trituración Mecánica: Camdriven stamps (510 per mill, dependiendo del modelo) are lifted and dropped onto the ore bed within the mortar box, applying repetitive impact force.
3. Formación de lodo & Descargar: Water is introduced during crushing to create a slurry. Continuously crushed material passes through a discharge screen at the mortar box's end, ensuring controlled particle size.

Ámbito de aplicación: Ideal for freemilling gold ores where cyanide leaching follows crushing. Suitable for small to mediumscale operations, toll processing facilities, and regions with reliable power but limited infrastructure for complex grinding circuits.

Limitaciones clave: Not designed for ultrafine grinding (sub100 mesh) as a standalone unit; primary crushing to appropriate feed size (típicamente 1") is required upstream. Performance on complex refractory ores will be limited without additional pretreatment.
