1. PEMBUKAAN PAINPOINT DRIVEN

Operating a quarry site in Lagos presents a distinct set of challenges that directly impact profitability and operational continuity. Are you grappling with the high cost and logistical complexity of transporting aggregates from distant quarries to your Lagosbased projects? Is inconsistent material quality from unreliable suppliers causing rework and project delays? Perhaps unpredictable equipment availability is stalling your production schedule, or you are managing the significant overhead of leased equipment with no longterm asset value. The search for a viable, costcontained source of highquality granite, Kerikil, or limestone within the Lagos commercial zone is a persistent operational hurdle. What if you could establish a controlled, efficient primary crushing operation closer to your point of use, turning a logistical burden into a competitive advantage?

2. GAMBARAN KESELURUHAN PRODUK: MOBILE PRIMARY CRUSHING PLANT FOR LAGOS QUARRY SITES

This solution centers on a trackmounted mobile jaw crusher, engineered specifically for the establishment and operation of efficient quarry sites in Lagos. It is designed for rapid deployment on virgin land or existing borrow pits to produce primary aggregate.

Aliran Kerja Operasi:
1. Site Positioning: The selfpropelled plant moves directly to the blast pile or excavation face, minimizing dump truck haulage within the site.
2. Pengurangan saiz utama: Besar (<900mm) granite boulders are fed into the vibrating grizzly feeder (VGFF VGF), which bypasses fines and directs oversize material into the robust jaw crusher.
3. Penyampaian Produk: Bahan yang dihancurkan dilepaskan ke penghantar produk utama, stockpiled directly for haulage or fed into a secondary screening module.

Skop Permohonan & Batasan:
Skop: Ideal for establishing new quarries, satellite crushing points, and processing virgin rock (granit, basalt) for construction aggregates (kursus asas, subbase). Suitable for contract crushing campaigns across multiple sites in Lagos and Ogun states.
Batasan: Not designed for final asphalt or concrete sand production without secondary/tertiary stages. Performance is contingent on proper feed size control and rock abrasiveness within designed specifications.
