Subjekti: Optimizing Material Sourcing: HighCapacity Screening Solutions for Lagos Quarry Operations

1. HAPJE NGA PIKA E DIKIMIT

Lagos quarry operators face a specific set of logistical and operational pressures. The demand for highgrade granite and aggregates for commercial construction in Lekki, Epe, and Ikorodu continues to outpace supply, yet your margins are squeezed by three persistent challenges:

Cilësi jokonsistente e furnizimit: Runofmine (ROM) material from local pits often contains high clay content and variable moisture levels (1525%), leading to blinding and pegging of conventional screens. This causes unscheduled downtime costing an estimated ₦850,000–₦1.2 million per hour in lost production.
Ndotja me gjoba: Inability to effectively remove minus5mm fines from your ¾inch and ½inch products results in rejected loads at the weighbridge, with rehandling costs adding ₦400–₦600 per ton to your operating expenses.
Grykat e ngushta të xhiros: Your current circuit struggles to maintain 250–300 tons per hour (TPH) during peak demand, forcing you to turn away contracts for the Eko Atlantic or Dangote refinery projects.

Is your current screening equipment engineered to handle the specific abrasiveness (Fortësia e Mohs 67) and highmoisture conditions of Lagos granite, or is it costing you contract penalties?

2. PËRMBLEDHJE E PRODUKTIT

Të Ekran vibrues me prirje HeavyDuty (Model LQS2460) is a primary classification unit designed specifically for the highthroughput, highwear environment of Lagos quarry sites. It processes ROM material after primary jaw crushing, delivering precise separation for concrete aggregate and asphalt base courses.

Rrjedha e punës operative:
1. Feed: Materiali ROM (0300mm) is fed via conveyor onto the screen’s heavyduty feed box.
2. Stratifikimi: Material travels down the 6.0m x 1.5m deck at a 20° incline, driven by a dualshaft exciter generating 6.5 Gforce.
3. Primary Separation: Top deck (50mm hapje) scalps oversize (+50mm) for recirculation to the secondary cone crusher.
4. Secondary Separation: Bottom deck (12mm or 19mm aperture) separates base course material from minus12mm fines.
5. Shkarkimi: Three product streams (tepër i madh, kursi bazë, gjobat) are directed to stockpile conveyors.

Fusha e Aplikimit: Suitable for dry and wet screening of granite, gneiss, dhe kuarcit. Kufizimet: Not designed for sticky clay content exceeding 30% without a prewash system; maximum feed temperature 60°C.

8. FAQ

P: Can the LQS2460 handle the high clay content typical of Lagos lateritic overburden?
A: po, for clay content up to 30%. The ball decks and variable angle feature prevent blinding. For clay exceeding 30%, we recommend the optional prewash system to slurry the fines before screening.

P: What is the typical lead time for delivery to a Lagos quarry site?
A: Standard units are available from our Apapa warehouse within 14 ditë pune. Konfigurimet e personalizuara (p.sh., special aperture sizes) kërkojnë 68 javë nga konfirmimi i porosisë.

P: How does this screen compare to a banana screen for base course production?
A: Banana screens offer higher capacity per unit area but are less effective at removing fines in wet conditions. For Lagos applications where moisture varies, the LQS2460’s adjustable angle provides more consistent efficiency. Të dhënat në terren tregojnë 3% better fines removal in wet conditions.

P: What is the expected lifespan of the polyurethane deck panels?
A: With proper feed distribution (no impact from +200mm rocks), panels last 4,0006,000 orët e punës. Panels are reversible, doubling life. Replacement cost per panel: ₦85,000.

P: Can this unit be integrated with an existing PLC system?
A: po. The VFD and vibration sensors are Modbus RTU compatible. We provide a standard RS485 interface. Custom integration with Siemens or AllenBradley systems is available as a service.

P: Çfarë trajnimi ofroni për operatorët e impianteve?
A: We include a 2day onsite training program covering startup procedures, angle adjustment for moisture conditions, panel replacement, and daily vibration monitoring. Refresher training is available at ₦450,000 per session. Luxury Quarry Sites In Lagos Companies

P: Cili është mbulimi i garancisë?
A: 24 muaj mbi komponentët strukturorë (trupi, exciter housing, burimet). 12 months on moving parts (kushinetat, boshte, motorët). Excludes wear items (astar, panels, rripat). Warranty covers parts replacement; labor is charged at ₦25,000 per hour for onsite work.
