1. PAINPOINT DRIVEN OPENING

Managing a commercial quarry site in Lagos presents distinct operational hurdles that directly impact your bottom line. Are you contending with the high cost and logistical delays of importing replacement parts for critical machinery? Is unscheduled downtime due to equipment failure under heavy, continuous loads causing significant production shortfalls? Are you struggling to maintain consistent product sizing and yield in the face of variable, hard Nigerian granite or limestone feed? Furthermore, does the operational expense of fuel and routine maintenance for primary crushing stages consume an unsustainable portion of your operating budget? These challenges are not merely inconveniences; they represent direct threats to project timelines, contractual obligations, and profitability. The central question becomes: how can you secure reliable, highvolume aggregate production with predictable operating costs and locally supportable equipment?

2. PRODUCT OVERVIEW

The Stationary Primary Jaw Crusher Plant is a cornerstone investment for hightonnage aggregate production on commercial quarry sites. Engineered for the first reduction stage, this system processes blasted rock feed (typically 0800mm) into a primary crushed product (typically 0150mm) for secondary processing.

Operational Workflow:
1. Feed: Dump trucks deposit raw, blasted quarry run material into a largecapacity vibrating grizzly feeder (VGF).
2. PreScreening & Crushing: The VGF removes natural fines and bypasses subsize material while evenly feeding oversize rock into the robust jaw crusher chamber.
3. Primary Reduction: The crusher's fixed and movable jaw plates apply immense compressive force to fracture the rock.
4. Discharge: Crushed material is discharged onto a main product conveyor for transport to the next stage of your plant.

Application Scope: Ideal for highcapacity (200600+ TPH) basalt, granite, and limestone quarries requiring a permanent, dedicated primary reduction solution.
Limitations: Not designed for mobile or semimobile applications where frequent relocation is required. Requires stable, prepared concrete foundations and significant upfront civil works.

6. APPLICATION SCENARIOS

LargeScale Granite Quarry, Lekki Axis | Challenge: A major operator faced chronic downtime from imported crushers failing under sustained load, with part replacements taking 8+ weeks via air freight. Production targets were consistently missed.| Solution: Installation of a heavyduty stationary jaw crusher plant designed for serviceability with component commonality.| Results: Mechanical availability increased to 94%. First major bearing service was completed by a Lagosbased team using locally sourced tools in five days. Annual production volume increased by 22% in the first year due to reduced stoppages.

Integrated Cement & Aggregate Producer, Ogun State | Challenge: Inefficient primary crushing created bottlenecks, limiting feed to secondary cones and VSI crushers. High fuel consumption from constantly running older equipment at maximum load was eroding margins.| Solution: Deployment of an automated primary jaw plant with optimized kinematics for higher reduction ratio in a single pass.| Results: Throughput to secondary stage improved by 30%. Plantwide specific energy consumption decreased by an estimated 18%, translating to substantial diesel cost savings across the full operation.
