1. PAINPOINT DRIVEN OPENING

Operating a quarry site in Lagos presents a distinct set of logistical and operational hurdles that directly impact profitability. Are you contending with the high cost and erratic supply of imported aggregates? Is your production bottlenecked by the inconsistent performance of underpowered or unsuitable crushing and screening equipment in the local climate? Are you managing excessive downtime due to equipment failures, compounded by lengthy lead times for spare parts and technical support? The cumulative effect is unpredictable output, escalating maintenance budgets, and missed project deadlines. Sourcing reliable, highcapacity primary crushing equipment is not merely a purchase; it is a strategic decision to stabilize your entire supply chain. How do you secure a consistent flow of highquality aggregate to meet Lagos's construction demands while controlling operational costs?

2. PRODUCT OVERVIEW

The cornerstone of an efficient Lagos quarry operation is a highperformance Primary Jaw Crusher engineered for robust, continuous duty in granite and hard rock applications. This heavyduty machinery forms the first critical stage in mineral processing, reducing blasted rock to manageable sizes for further refinement.

Operational Workflow:
1. Feed: Dump trucks deposit large blasted rock (shot rock) directly into the crusher's vibrating grizzly feeder.
2. Crushing: The jaw crusher’s fixed and movable jaws exert immense mechanical pressure, fracturing the rock through compressive force.
3. Separation: The grizzly section bypasses subsize material directly to the discharge conveyor, optimizing capacity.
4. Discharge: Crushed product is conveyed to the next stage of processing, typically a secondary cone crusher or screening plant.

Application Scope: Ideal for hightonnage primary reduction of abrasive granite, basalt, and other hard rock formations common to quarries in southwestern Nigeria.

Limitations: Not designed for recycled concrete or asphalt as a primary feed material without specific configuration; requires competent foundational support and consistent, largevolume feed for optimal efficiency.

3. CORE FEATURES

Deep Crushing Chamber & Aggressive Toggle | Technical Basis: Enhanced nip angle and stroke | Operational Benefit: Increases capacity and ensures aggressive reduction of large feed material | ROI Impact: Higher throughput per fuel hour reduces cost per ton

HeavyDuty Fabricated Frame | Technical Basis: Highgrade steel plate with reinforced ribbing | Operational Benefit: Withstands the stresses of continuous hard rock crushing and unstable grid power startups | ROI Impact: Minimizes structural fatigue failures, extending asset life by years

Integrated Vibrating Grizzly Feeder (VGF) | Technical Basis: Prescreening section with adjustable grizzly bars | Operational Benefit: Removes fines prior to crushing, reducing chamber wear and preventing clogging during wet season operations | ROI Impact: Directly reduces liner wear costs and improves total system throughput by up to 20%

Hydraulic Toggle Adjustment System | Technical Basis: Replaceable hydraulic cylinders for setting adjustment | Operational Benefit: Allows operators to adjust crusher discharge settings quickly and safely from a central location | ROI Impact: Reduces downtime for product size changes from hours to minutes, maximizing operational flexibility

Centralized Greasing System | Technical Basis: Automated lubrication points routed to a single station | Operational Benefit: Ensures critical bearing points are lubricated consistently, even in dusty conditions | ROI Impact: Prevents premature bearing failure—a leading cause of unplanned downtime—and extends service intervals

CorrosionResistant Component Finishing | Technical Basis: Specialized paint systems and protective treatments on electricals | Operational Benefit: Mitigates accelerated wear from Lagos’s coastal humidity and saline air | ROI Impact: Protects component integrity, maintaining resale value and reducing cosmetic maintenance
