1. PEMBUKAAN PAINPOINT DRIVEN

Managing quarry sites in Lagos presents distinct operational and logistical hurdles that directly impact profitability and export compliance. Are you contending with inconsistent aggregate quality leading to rejected export shipments? Are logistics bottlenecks and port delays causing missed delivery windows and contractual penalties? Is the high cost of inland transportation from your quarry sites in Lagos to Apapa or Tin Can ports eroding your margin on every ton? Tambahan pula, do manual sizing and sorting processes create unpredictable yield, wasting valuable resource and limiting your ability to fulfill large, standardized export orders? These challenges are compounded by equipment downtime in a harsh environment, where every hour of lost production delays revenue. Persoalan utama untuk pengeksport ialah ini: how can you establish a reliable, highvolume supply chain from your quarry face to the port that consistently meets international aggregate specifications?

2. GAMBARAN KESELURUHAN PRODUK: MODULAR CRUSHING & SCREENING PLANTS FOR EXPORTREADY AGGREGATE

For quarry operators targeting export markets from Lagos, a stationary or semimobile crushing and screening plant is the core solution. This integrated system transforms blasted rock into precisely graded, washed, and stockpiled aggregates ready for direct loading onto export vessels.

The operational workflow is engineered for export efficiency:
1. Penghancuran utama: Large feed material from the quarry face is reduced by a robust jaw crusher.
2. Penghancuran Menengah/Tertiari & Pemeriksaan: Cone crushers further refine the material, which is simultaneously screened via vibrating screens to separate sizes.
3. Aggregate Washing: Sand particles and fine aggregates are processed through a screw classifier or sand plant to remove silt and impurities, meeting strict cleanliness standards for concrete aggregate.
4. Pengisihan Akhir & Stok: Correctly sized and washed material is conveyed to dedicated stockpiles via radial stackers, creating segregated product bays for efficient loadout.

Skop Permohonan: Ideal for mediumtolarge scale granite or limestone quarry sites in Lagos producing aggregates (10mm, 12mm, 20mm, pasir tajam) for construction and concrete markets. Batasan: Requires stable site preparation and grid or heavyduty generator power; not suitable for highly mobile, smallscale operations.

6. SENARIO APLIKASI

Granite Aggregate Exporter Challenge near Ikorodu

Cabaran:A quarry producing granite aggregates faced frequent shipment rejections at the port due to excessive silt content (>5%) in their sharp sand fraction.
Penyelesaian:A turnkey modular plant was installed featuring an emphasized washing circuit with a dual screw sand plant.
Keputusan:Silt content consistently reduced below 2%. The exporter secured a longterm contract with a readymix concrete supplier in West Africa based on guaranteed quality specs.

LargeScale Limestone Operation Targeting Multiple Grades
