1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Operating a quarry site in Lagos presents a distinct set of challenges that directly impact profitability and operational continuity. Are you grappling with the high cost and logistical complexity of transporting aggregates from distant quarries to your Lagosbased projects? Is inconsistent material quality from unreliable suppliers causing rework and project delays? Perhaps unpredictable equipment availability is stalling your production schedule, or you are managing the significant overhead of leased equipment with no longterm asset value. The search for a viable, costcontained source of highquality granite, grava, or limestone within the Lagos commercial zone is a persistent operational hurdle. What if you could establish a controlled, efficient primary crushing operation closer to your point of use, turning a logistical burden into a competitive advantage?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO: MOBILE PRIMARY CRUSHING PLANT FOR LAGOS QUARRY SITES

This solution centers on a trackmounted mobile jaw crusher, engineered specifically for the establishment and operation of efficient quarry sites in Lagos. It is designed for rapid deployment on virgin land or existing borrow pits to produce primary aggregate.

Flujo de trabajo operativo:
1. Site Positioning: The selfpropelled plant moves directly to the blast pile or excavation face, minimizing dump truck haulage within the site.
2. Reducción de tamaño primario: Grande (<900milímetros) granite boulders are fed into the vibrating grizzly feeder (VGF VGF), which bypasses fines and directs oversize material into the robust jaw crusher.
3. Transporte de productos: El material triturado se descarga en un transportador principal de producto., stockpiled directly for haulage or fed into a secondary screening module.

Ámbito de aplicación & Limitaciones:
Alcance: Ideal for establishing new quarries, satellite crushing points, and processing virgin rock (granito, basalto) for construction aggregates (curso base, subbase). Suitable for contract crushing campaigns across multiple sites in Lagos and Ogun states.
Limitaciones: Not designed for final asphalt or concrete sand production without secondary/tertiary stages. Performance is contingent on proper feed size control and rock abrasiveness within designed specifications.

3. CARACTERÍSTICAS PRINCIPALES

TrackMounted Mobility | Base técnica: Hydraulic drive tracks with high ground clearance | Beneficio operativo: Enables rapid relocation between sites or within a large quarry with minimal support equipment, critical for navigating Lagos’s varied terrain. | Impacto del retorno de la inversión: Eliminates fixed plant infrastructure costs and reduces setup/teardown time from weeks to days, accelerating project startup.

Trituradora de mandíbulas de servicio pesado | Base técnica: Forged eccentric shaft and large spherical roller bearings | Beneficio operativo: Consistently processes hard Lagos granite with reduced risk of premature wear or catastrophic bearing failure under shock loading. | Impacto del retorno de la inversión: Aumenta el tiempo medio entre fallas. (MTBF), lowering costpertonne for wear parts and unscheduled downtime.

Integrated Vibrating Grizzly Feeder (VGF VGF) | Base técnica: Twostep prescreening with adjustable grizzly bars | Beneficio operativo: Removes natural fines and separates subsize material before crushing, increasing throughput and reducing crusher wear. | Impacto del retorno de la inversión: Mejora la eficiencia general de la planta al 1525%, directly lowering fuel consumption per tonne produced.

OnBoard Power Pack | Base técnica: Nivel 4 Final/Tier 3 diesel generator set integrated into chassis | Beneficio operativo: Provides complete power independence; operates in remote grid locations common around new quarry sites in Lagos’s outskirts. | Impacto del retorno de la inversión: Removes dependency on unstable grid power or separate generator hire, ensuring uninterrupted production.

Sistema de control PLC centralizado | Base técnica: Singlepoint monitoring of engine parameters, configuración de la trituradora, and conveyor operations | Beneficio operativo: Allows one operator to safely control the entire crushing cycle from a soundproofed cabin. | Impacto del retorno de la inversión: Reduces labor requirements and enhances operational safety through system diagnostics and emergency stops.

QuickSetup Support Legs | Base técnica: Hydraulically deployed outriggers with large pads | Beneficio operativo: Provides stable operating platform on uneven ground without extensive civil works, ensuring proper crusher alignment and vibration damping. | ROI Impact Cuts site preparation time and cost by up to 70% compared to fixed foundation requirements.
