1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

La gestión de una planta trituradora de mineral de hierro presenta distintas, desafíos de alto costo que impactan directamente sus resultados. ¿Estás luchando con:
Tiempo de inactividad excesivo para mantenimiento: Frequent liner changes and unplanned stops to address wear in primary and secondary crushers, Cuesta cientos de horas de producción al año..
Unpredictable Throughput Volatility: Inconsistent feed size and hardness leading to chokefed crushers or idle downstream processes, reduciendo la eficiencia general de la planta al 1525%.
Spiraling Operational Costs: Premature failure of wear parts under highabrasion conditions, with replacement costs for liners, mantos, and jaws representing a significant recurring capital expenditure.
Inconsistencia en la calidad del producto: Inability to reliably produce a consistent 40mm or 20mm product, causing bottlenecks in grinding circuits and pelletizing plants.

La pregunta central es: how can you achieve predictable, hightonnage crushing with lower costpertonne and improved system reliability? La solución radica en especificar un diseño específico planta trituradora de mineral de hierro.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

Un planta trituradora de mineral de hierro is a engineered system of primary, secundario, and often tertiary stationary crushers, pantallas, and material handling conveyors designed specifically for the highvolume reduction of runofmine (memoria de sólo lectura) hematite or magnetite ore.

Flujo de trabajo operativo:
1. Trituración Primaria: mineral ROM (hasta 1,5 m) se reduce a <250mm typically using a gyratory or jaw crusher built for high throughput and abrasive service.
2. Trituración Secundaria: El material se reduce aún más a <75mm via cone crushers configured for heavyduty crushing pressure.
3. Cribado & Trituración Terciaria: Screens classify material; onspec product is sent to stockpile, while oversize is recirculated through tertiary cone crushers for closedcircuit operation.
4. Manejo de materiales: A network of heavyduty conveyors transfers material between stages.

Ámbito de aplicación: Designed for largescale mining operations processing >5 million tonnes per annum (Mtpa) of abrasive iron ore.
Limitaciones: Not suitable for smallscale or pilot operations under 1 Mtpa due to capital intensity. Requires stable feed consistency from upstream mining operations for optimal performance.
