1. PAINPOINT DRIVEN OPENING

Are your quarry operations in Lagos struggling with unpredictable production costs and logistical bottlenecks? Sourcing consistent, affordable aggregate from local quarry sites in Lagos presents distinct challenges: volatile pricing from multiple suppliers, inconsistent material quality leading to mix design failures, and logistical delays that idle your entire fleet. These issues directly translate to budget overruns and missed project deadlines.

How do you stabilize your input costs and secure a reliable supply chain for granite, gravel, or limestone? Is there a way to bring more control over aggregate quality and availability to protect your project margins? The solution lies in evaluating the operational efficiency of the primary production source itself—the quarry site. Upgrading core processing equipment is a strategic response to these commercial pressures.

2. PRODUCT OVERVIEW: MOBILE TRACKMOUNTED CRUSHING & SCREENING PLANT

This product description focuses on mobile trackmounted crushing and screening plants, the optimal equipment solution for enhancing productivity at quarry sites in Lagos. These selfcontained units are engineered for rapid deployment and highvolume aggregate production in challenging environments.

Operational Workflow:
1. Primary Crushing: Excavatorfed large feed material is reduced by a robust jaw crusher.
2. Intermediate Screening & Conveying: A vibrating screen separates sized product from oversize material, which is conveyed to the secondary circuit.
3. Secondary/Tertiary Crushing: A cone crusher further refines oversize material for precise cubical shaping.
4. Final Screening & Stockpiling: Multiple deck screens sort crushed material into specified aggregates (e.g., ¾”, ½”, stone dust), which are conveyed to designated stockpiles.

Application Scope: Ideal for mediumtolarge scale granite and limestone quarry sites requiring high mobility between faces or for contractors operating multiple sites. Suitable for producing all standard construction aggregates.

Limitations: Not designed for hard rock mining (e.g., iron ore) or as a stationary plant for megaquarries requiring >500 tons per hour fixed capacity. Feed size is limited by the specific model’s jaw crusher opening.

3. CORE FEATURES

Direct Feed System | Technical Basis: Integrated vibrating grizzly feeder (VGF) with bypass chute | Operational Benefit: Removes fines and natural sand prior to primary crushing, reducing wear on the jaw plates and preventing crusher clogging during wet conditions common in Lagos | ROI Impact: Up to 15% reduction in jaw liner wear costs and elimination of related downtime

Hybrid DieselElectric Drive | Technical Basis: Diesel generator powers electric crusher and screen motors | Operational Benefit: Significant fuel savings compared to direct dieselhydraulic drives; provides consistent power output for optimal crushing chamber performance | ROI Impact: Field data shows 2030% lower fuel consumption per ton crushed, directly lowering operating cost

Advanced Automation System | Technical Basis: PLCbased control with touchscreen interface | Operational Benefit: Your operators can monitor production rates, adjust settings, and diagnose issues from a central location; enables precise control over final product gradation | ROI Impact: Reduces product waste due to offspec material by an average of 8%

Quick Setup & Relocation Mechanism | Technical Basis: Hydraulic folding conveyors and trackdriven movement | Operational Benefit: Plant can be fully operational within 30 minutes of arrival on a new face or site, maximizing asset utilization across projects | ROI Impact Minimizes nonrevenue generating move time, allowing more bids on shortduration projects

HeavyDuty Dust Suppression | Technical Basis: Pressurized water spray system with strategically placed nozzles at transfer points | Operational Benefit: Maintains compliance with environmental considerations and protects worker health by suppressing airborne particulate | ROI Impact Avoids potential work stoppages and fines related to environmental noncompliance

6. APPLICATION SCENARIOS

Commercial ReadyMix Concrete Producer Owning a Quarry Site Near Lekki / Epe Axis

Challenge: Inconsistent aggregate gradation from older fixed plant was causing variability in concrete slump and strength, leading to batch rejections. High maintenance costs were eroding margins.
Solution: Deployment of an MC250 mobile plant dedicated to producing precisely graded aggregates (12mm & 19mm granite) for their concrete batching plant.
Results: Achieved consistent FM sand and aggregate grading eliminated batch rejections within six months. The plant’s mobility allowed them to process two different quarry faces without capital investment in conveyors.

Road Construction Contractor with Multiple Sites Across SouthWest Nigeria

Challenge: High cost and delay in sourcing certified base course material from thirdparty quarry sites in Lagos for different project locations.
Solution: Utilization of a mobile crushing plant moved between project sites to process locally sourced rock into approved base material (DTp1 / Subbase).
Results: Reduced aggregate procurement costs by an estimated 40% per project through elimination of middlemen transport logistics gained full control over supply schedule cutting project delays related t o material delivery by an average o f three weeks

LargeScale Granite Quarry Site Supplying Lagos Market

Challenge: Existing twostage stationary plant created bottlenecks; any maintenance stopped all production Secondary circuit was inefficient producing excess fines reducing yield o f premium chippings
