1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

La gestión de una cantera en Lagos presenta distintos obstáculos operativos. Are you contending with the high cost and logistical complexity of importing replacement parts for critical machinery? Is unpredictable equipment downtime due to abrasive local granite and basalt formations disrupting your production schedules and contractual commitments? Además, do you face challenges in maintaining consistent product sizing and yield in highvolume aggregate production to meet Lagos’s intense construction demands? These factors directly impact your bottom line through lost revenue, inflated maintenance budgets, and missed project timelines. La pregunta central para los gerentes de planta es esta: how can you secure robust, reliable processing equipment engineered for Nigerian conditions that delivers predictable output and protects your operational investment?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

Este contenido se centra en Plantas estacionarias de trituración y cribado designed for highvolume aggregate production in granite and basalt quarries. These integrated systems are the core solution for transforming blasted rock into specified aggregate sizes.

Flujo de trabajo operativo:
1. Reducción Primaria: Los camiones volquete alimentan grandes rocas voladas (≤ 800mm) into a primary jaw crusher for initial size reduction.
2. Trituración Secundaria/Terciaria: The material is conveyed to a cone crusher for further reduction, producing intermediate sizes.
3. Apresto & Clasificación: Material is routed through vibrating screens to separate aggregates into precise fractions (p.ej., 3/4", 1/2", arena afilada).
4. Almacenamiento: Los agregados del tamaño correcto se transportan a las pilas de almacenamiento designadas mediante apiladores radiales..
5. Recirculación: Oversized material is automatically fed back into the crusher circuit for reprocessing.

Ámbito de aplicación & Limitaciones:
Alcance: Ideal for medium to largescale quarry operations producing aggregates for concrete, asfalto, base de la carretera, y capas de drenaje. Suited for hard rock formations prevalent in Nigerian quarries.
Limitaciones: Not suitable for soft or nonabrasive materials like limestone where different crusher types may be more efficient. Requiere estabilidad, prepared ground for installation and consistent electrical power supply or dedicated generator capacity.

6. ESCENARIOS DE APLICACIÓN

Ampliación de cantera de granito, Área del corredor

Desafío:Se necesita una cantera para aumentar la producción en más de 50% to fulfill a major road contract but had limited space for a second parallel processing line.
Solución:A highefficiency threestage stationary crushing plant was installed featuring a large jaw crusher followed by a single multicylinder hydraulic cone crusher capable of producing multiple products in one pass.
Resultados:The plant achieved a sustained output of over 280 TPH within the existing operational footprint.The improved cubicity of the aggregate also commanded a higher market price.

Basalt Aggregate Production For Concrete

Desafío: A producer faced inconsistent particle shape ("escamadura") from their older impact crusher when processing hard basalt.This led to poor concrete workability rejection by readymix plants.Solución: Implementation of a stationary plant centered on a heavyduty gyratory cone crusher configured with a fineliner profile optimized specificallyfor chiplike basalt.Resultados: Field data shows flakiness index improved from over 35%to under 20%,meeting stringent concrete spec requirements.Product consistency reduced customer complaintsby over 90%.
