1. PAINPOINT DRIVEN OPENING

Are you managing a quarry operation in Lagos where logistical bottlenecks and equipment inefficiency are eroding your export margins? The challenges of sourcing, processing, and transporting bulk aggregates for the export market are compounded by local operational constraints. Are you experiencing:
High Rehandling Costs: Multiple loading cycles between inefficient primary crushers and screening plants, increasing fuel, labor, and equipment wear.
Inconsistent Feed Material: Variable rock hardness and size from your Lagos quarry site leading to frequent crusher jams, unplanned downtime, and unpredictable final product gradation.
Port Logistics Delays: Inability to rapidly process and stockpile specified aggregate sizes, causing missed shipping windows and contractual penalties.
Excessive Operational Costs: Skyhigh fuel consumption from underoptimized plant machinery and the financial drain of importing unsuitable, nontropicalized equipment that fails prematurely.

The central question for exporters is this: how do you transform your Lagos quarry site into a reliable, highvolume supply chain asset that consistently meets international aggregate specifications while controlling operational expenditure?

2. PRODUCT OVERVIEW

The solution is a stationary granite crushing and screening plant, engineered specifically for highvolume production in West African quarry environments. This integrated plant system is designed to transform raw blasted rock into precisely graded aggregates for construction and industrial export markets.

Operational Workflow:
1. Primary Crushing: Dump trucks feed raw granite into a robust primary jaw crusher for initial size reduction.
2. Secondary & Tertiary Crushing: Material is conveyed to cone crushers for further reduction, creating cubical product shapes critical for highspecification applications.
3. PreScreening & Sorting: Vibrating screens separate material before final crushing stages to optimize efficiency and reduce wear.
4. Final Sizing & Stockpiling: Multideck screens sort the crushed material into exact product fractions (e.g., 3/4", 1/2", stone dust), which are conveyed to dedicated stockpiles for direct loadout.

Application Scope & Limitations:
Scope: Ideal for medium to largescale granite quarry operations targeting consistent production of 150600+ TPH of sized aggregates. Suited for fixed or semifixed installation at primary quarry sites serving Lagos export channels.
Limitations: Not designed for smallscale or artisanal mining. Requires stable site preparation and grid or heavyduty generator power supply. Initial capital investment is targeted at operations with confirmed longterm export contracts.
