Targeting Quarry Managers & Aggregate Producers in Lagos: Overcoming SiteSpecific Challenges

Are you managing a bespoke quarry site in Lagos where inconsistent geology, space constraints, and abrasive laterite deposits drive up maintenance costs and cripple production schedules? The challenges of extracting highquality granite, limestone, or gravel in Nigeria’s commercial hub are unique. Downtime from equipment mismatch can cost millions of Naira per day in lost revenue. How do you maintain consistent feed to your crushers when face conditions change daily? Is your processing plant flexible enough to handle variable rock hardness without constant recalibration? Are you sacrificing final product spec to meet output targets?

Product Overview: Modular, HighYield Crushing and Screening Plants for Bespoke Lagos Quarries

Our engineered solution is a range of modular, trackmounted primary crushing and screening plants specifically configured for the variable conditions of bespoke quarry sites in Lagos. This equipment is designed for operations where fixed plant infrastructure is impractical due to site size, lease terms, or shifting extraction faces.

Operational Workflow:
1. Primary Size Reduction: Mobile primary jaw crusher receives blasted material directly from the face, reducing oversized rock.
2. PreScreening & Scalping: Integrated heavyduty grizzly or scalper removes fine, abrasive laterite and sand before intermediate crushing, protecting downstream components.
3. Secondary Processing: Closedcircuit cone crusher or impactor provides precise cubical product shaping for highvalue aggregate.
4. Product Sorting: Multideck vibrating screens separate output into clean, specready fractions (e.g., 3/4", 1/2", sharp sand).
5. Stockpiling: Radial conveyors create segregated stockpiles without requiring additional wheel loaders.

Application Scope & Limitations:
Scope: Ideal for mediumscale granite, limestone, and hard rock quarries with production targets of 150400 tons per hour. Suited for sites with limited laydown area common in Lagos environs.
Limitations: Not designed for largescale, fixedplant mining exceeding 600 tph or for processing heavily claybound material without prewashing systems.

Core Features: Designed for Durability and Simplicity

Adaptive Crushing Chamber | Technical Basis: Hydraulically adjustable CSS (Closed Side Setting) and reversible hydropneumatic tramp release system | Operational Benefit: Operators can adjust product size in under 2 minutes to accommodate changes in rock hardness or product demand without stopping feed. The tramp release protects the crusher from uncrushables like rebar. | ROI Impact: Eliminates 12 hours of daily downtime for manual adjustment; prevents an average of NGN 810M in potential damage from tramp iron events annually.

AbrasionResistant Material Circuit | Technical Basis: Hardox® liners on hoppers and chutes; manganese steel crusher jaws/concaves; ceramiclined slurry pumps on optional wash plants. | Operational Benefit: Directly counters the highsilica content and abrasive nature of Lagos quarry materials, extending wear part life by up to 40%. | ROI Impact: Reduces wear part inventory costs and changeout frequency, lowering costperton by an estimated 1520%.

Dust Suppression System | Technical Basis: Highpressure misting nozzles with solenoid valves tied to conveyor start/stop controls and water recycling settlement tanks. | Operational Benefit: Actively manages airborne particulate at each transfer point, ensuring compliance with Lagos State environmental standards and protecting worker health. | ROI Impact: Mitigates risk of work stoppage fines from regulatory bodies and reduces respiratoryrelated absenteeism.

Rapid Mobility & Setup | Technical Basis: Trackmounted chassis with hydraulic folding conveyors and singlepowerpack engine configuration. | Operational Benefit: Enables the entire primary section to relocate between faces or within the site in under 30 minutes using a standard excavator. | Operational Benefit: Maximizes utilization by keeping the plant close to the active face, reducing cycle times for haul trucks or loaders.

Intuitive Control System | Technical Basis: Centralized PLCbased control panel with touchscreen HMI displaying realtime power draw, throughput rates, and CSS. | Operational Benefit: Allows a single operator to monitor and control the entire crushing sequence, identifying bottlenecks like a screen overload immediately. | ROI Impact: Optimizes feed rate for energy efficiency; reduces required personnel on the plant floor.

Application Scenarios

Granite Quarry Operation in Lekki Axis

Challenge: A quarry supplying concrete batching plants faced inconsistent product cubicity from a dated jawcone setup when rock fissuring changed, leading to batch plant rejections.
Solution: Implementation of our trackmounted cone crusher plant with an advanced automatic setting regulation system.
Results: Achieved consistent product elongation index below <15%, eliminating rejections. Plant mobility allowed following the bestquality vein, improving overall yield by 22%.

Integrated Sand & Gravel Producer near Ikorodu

Challenge: Need to process a mixed deposit of gravel lenses and sand layers with one flexible setup to produce washed concrete sand and three aggregate sizes.
Solution: A modular crushing circuit paired with an integrated fines recovery screw classifier and washing screen.
Results: Singleplant operation now produces four specification products simultaneously at 220 TPH total yield—a previously unattainable outcome—reducing fuel costs by centralizing processing.
