1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR
Your fabrication yard in Lagos is losing 12–18 hours of productive cutting time per week due to inconsistent granite feed from local quarry sources. The cost? Approximately ₦850,000 per shift in idle labor and equipment overhead. When your fabricators wait for graded aggregates, your project deadlines slip, and penalty clauses on commercial contracts start accruing at 2% par semaine.
Are your current material suppliers delivering the precise ¾inch or ½inch chippings required for your steel reinforcement molds and precast forms? Do you have a reliable, onsite solution to process raw boulders into specificationgrade aggregates without depending on thirdparty quarry schedules?
Professional quarry sites in Lagos fabricators need a mobile, highcapacity crushing and screening system that integrates directly into their yard workflow—eliminating supply chain dependency while maintaining strict particle size control for structural concrete components.
2. APERÇU DU PRODUIT
Le Lagos Fabricator Series Mobile Jaw & Cone Crusher Plant (Model LFC450) is a dieselelectric hybrid processing unit designed specifically for fabrication yards requiring ondemand aggregate production.
Flux de travail opérationnel:
1. Consommation alimentaire: Raw boulders (up to 600mm) are loaded into the vibrating grizzly feeder via wheel loader or excavator
2. Concassage primaire: Material passes through the heavyduty jaw crusher (450capacité tph) reducing to 150mm minus
3. Concassage secondaire: Conveyed to the cone crusher chamber for tertiary reduction to target sizes (6mm–25mm)
4. Dépistage: Tripledeck vibrating screen separates material into three fractions: amendes (0–5mm), puces (5–14mm), and coarse aggregates (14–25mm)
5. Stockage: Each fraction is discharged via independent conveyors for direct use in fabrication molds

8 FAQ
Q1 Can this equipment process recycled concrete containing rebar?
Yes.The hydraulic tramp release system handles occasional steel inclusion up todiameter20 mmand length300 mm.For continuous reinforced feed stock we recommend addingthe optional magnetic separator which removes ferrous metals before secondary crushing stage.
Q2 What is the typical lead time between order placement and delivery?
Standard lead timeis16 weeksfrom order confirmation including factory assembly sea freight clearanceand Lagos port delivery.Elite package customers receive priority scheduling reducing lead timeto12 weeks.We maintain two prebuilt unitsin Apapa warehousefor urgent requirementsdelivery within10 business days subjectto availability.
Q3 How does this compare against renting mobile crushers monthly?
Rental ratesfor comparable capacityunits range between ₦18millionand25millionper monthexcluding fuel operator accommodationand mobilizationfees.After24months rental payments exceed purchase priceofthe standard configuration.Ownership provides depreciation benefits tax advantagesand asset value retention estimatedat55%65 %afterfive yearsdependingon maintenancehistory.
Q4 What electrical infrastructure is required if running solely on grid power?
Minimum requirementis400Athreephase supplyat415V±10 %with dedicated transformer rating minimum500 kVA.We recommend installing surge protection device ratedat200 kA because Lagos grid experiences frequent voltage spikes exceeding600Vduring restoration events which can damage PLCcomponents without proper protection .
Q5 Can output size be changed during operation without stopping production?
Yes .The cone crusher featureshydraulic CSS adjustment allowing operators change closed side setting between6 mmand38 mmwhile machine runs .However we recommend performing adjustments during conveyor empty cycles(minutes30 )to prevent mixing fractions .Jaw crusher requires stopforadjustment procedure taking approximately three minutes .
Q6 What environmental permits are needed before installation in Lagos ?
You require permitfrom Lagos State Environmental Protection Agency(LASEPA )for stationary crushing operations .Our Elite package includes prefilled application forms site noise impact assessment report dust dispersion modeling study which reduces approval timelinefrom typical12 weeksto four weeks .Additionally obtain permitfrom local government area council covering operational noise limits between7 AM 6 PM daily .
Q7 How often must manganese wear parts be replaced under normal granite processing ?
With fresh granite having abrasion index(Aï )between0 .45 0 .65 jaw dies typically last800 1200operating hours while cone liners last600 900hours dependingon closed side setting tighter settings increase wear rateapproximately15 %.Our Wear Parts Subscription Program includes proactive replacement basedon IoT sensor data ensuring you never operate below70 %remaining liner thickness avoiding riskof breaking main frame due excessive stress concentrations .
