1. PYNPUNT GEDREWE OPENING

Managing a quarry site supplying a highvolume Lagos assembly plant presents distinct logistical and operational pressures. Inconsistent aggregate supply directly halts production lines, incurring contractual penalties and idling labor. Staan jy in die gesig:
Onbeplande stilstand: Crusher or screen failures causing 2448 hour delays in material delivery, disrupting the plant’s JustInTime schedule?
Inkonsekwente gradering: Variable particle size in your output, leading to rejected loads at the assembly plant’s QC checkpoint and wasted haulage costs?
Buitensporige bedryfskoste: Rising fuel, onderhoud, and labor expenses per ton of processed material eroding your margin on fixedprice supply contracts?
Opeenhoping van die terrein & Veiligheidsrisiko's: Inefficient material flow creating bottlenecks at loading points, increasing cycle times and pedestrianvehicle interaction?

The reliability of your entire operation hinges on the resilience and precision of your primary crushing and screening setup. How do you secure a consistent, specificationperfect aggregate supply to meet relentless demand?

2. PRODUK OORSIG

The solution is a trackmounted primary jaw crushing plant, engineered specifically for the highoutput, abrasive conditions of granite quarrying in Lagos. This mobile primary crusher serves as the first critical reduction stage, processing blasted rock into conveyable aggregate for secondary processing or direct use.

Operasionele werkvloei:
1. Excavator or wheel loader feeds blasted rock (0700mm) direk in die vibrerende grizzly feeder.
2. The grizzly bypasses sub100mm fines to a side conveyor while directing oversize to the robust jaw crusher chamber.
3. The hydraulic adjustment CSS (Geslote kant-instelling) allows operators to dial in the primary crush size (typically 125175mm) in minutes.
4. Crushed material is discharged onto the main product conveyor for stockpiling or direct feed to downstream screens.
5. The entire unit relocates within the quarry via its integrated tracks, following the face to minimize haul truck cycle distances.

Toepassingsomvang: Ideal for mediumtolarge granite quarries supplying construction aggregates (3/4”, 1/2”, basiskursus). It is designed as a primary reduction unit and requires secondary screening for final product gradation.

Beperkings: Not suitable for processing heavily reinforced concrete or asphalt recycling without specific prescreening and modifications. Maksimum voergrootte word bepaal deur modelkeuse.

6. TOEPASSINGSSCENARIO'S

Granite Quarry Supplying ReadyMix Concrete Plants & Block Industries in Ikorodu/Ota Axis

Uitdaging: A quarry operator faced frequent bottlenecks at their fixed primary plant due to increasing haul distances as the pit expanded. Truck cycle times were escalating, limiting daily output.
Oplossing: Implementation of a trackmounted primary jaw crusher that could be repositioned weekly along the advancing quarry face.
Resultate: Haul truck cycle distance reduced by an average of 60%. This translated to a 22% increase in daily shipped tonnage using the same truck fleet and a measurable decrease in diesel consumption per ton hauled.

LargeScale Quarry Feeding a Major Road Construction Project

Uitdaging: Strict project timelines required multiple aggregate specifications (1”, ¾”) from the same rock face with minimal changeover delay.
Oplossing: Utilizing the hydraulic CSS adjustment feature of the trackmounted jaw crusher to alter primary product size rapidly between shifts.
Resultate: Product size changeovers completed in under 15 minutes instead of several hours. This flexibility allowed simultaneous feeding of two separate stockpiles from one face without compromising crusher utilization or project schedule.
