1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

¿Está usted gestionando operaciones de recuperación de oro agobiadas por un rendimiento inconsistente?, costos de mantenimiento excesivos, and inefficient liberation of values from complex ores? Legacy crushing and grinding circuits often struggle with hard rock material, leading to premature wear part failure, tiempo de inactividad no planificado para cambios de revestimiento, and suboptimal particle size distribution for downstream cyanidation or gravity concentration. This directly impacts your bottom line through lost production hours, high consumable costs, and potential gold losses in coarse tailings. How can you increase milling capacity while controlling operational expenditure? Is your current process reliably delivering the optimal grind size for maximum gold recovery? La solución reside en una ingeniería específica, robust technology designed for this specific task.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

Esta línea de productos comprende trabajos pesados. Molinos de sellos engineered for the primary crushing and coarse grinding of goldbearing ores. As an OEM factory, we specialize in the direct sourcing and manufacturing of these mills for commercialscale mining and processing operations.

Flujo de trabajo operativo:
1. Introducción al feed: Runofmine or primarycrushed ore is fed into a mortar box.
2. Percussive Grinding: Sellos levantados mecánicamente (varillas ponderadas con mazos) se dejan caer secuencialmente sobre el mineral.
3. Reducción del tamaño de partículas: The repeated impact fractures the rock material.
4. Descarga de lodo: A continuous wash of water carries the ground slurry through a perforated screen plate for discharge.
5. Concentración de gravedad: The slurry is often directed directly over amalgamation plates or to downstream concentrators like shaking tables.

Ámbito de aplicación & Limitaciones:
Alcance: Ideal for freemilling gold ores, particularly in remote locations or smallerscale operations where simplicity, fiabilidad, and the ability to process coarse feed are paramount. Effective as a primary grinder ahead of finer milling circuits or for direct amalgamation.
Limitaciones: No apto para requisitos de molienda ultrafina. (p.ej., abajo 150 malla). Efficiency decreases with very wet, clayrich ores that can cause packing. Requires a consistent feed size to maintain optimal performance.
