1. PYNPUNT GEDREWE OPENING

Die bestuur van 'n steengroefperseel in Lagos bied duidelike operasionele struikelblokke wat 'n direkte impak op u winspunt het. Are you contending with inconsistent feed material from weathered overburden and hard granite variations, leading to premature crusher wear and unplanned maintenance? Is your production throughput limited by the logistical bottlenecks of moving material between primary, sekondêr, and tertiary crushing stages? Verder, do you face escalating costs and project delays due to equipment downtime from abrasive Lagos conditions and the difficulty of sourcing specialized technical support locally? These challenges erode profitability in a competitive market. Die oplossing lê nie net in masjinerie nie, but in a strategically selected, robustly engineered quarry plant designed for the specific demands of Nigerian aggregate production.

2. PRODUK OORSIG

'n moderne, stilstaande quarry plant is an integrated processing system engineered to transform blasted rock into precisely graded aggregates for construction and infrastructure projects. The operational workflow is a continuous cycle: (1) Primêre verplettering: Dump trucks feed large blasted rock into a jaw crusher for initial size reduction. (2) Sekondêr & Tersiêre verplettering: Material is conveyed to cone or impact crushers for further refinement to required chip sizes. (3) Sifting & Sorteer: Vibrating screens separate crushed material into different aggregate grades (bv., ¾”, ½”, stof). (4) Voorraad opgaar & Laai tans: Sorted aggregates are conveyed to designated stockpiles for direct loading onto trucks. This solution is scoped for highvolume, fixedlocation production but requires significant initial capital investment and site preparation; it is not suitable for smallscale or frequently mobile operations.

6. TOEPASSINGSSCENARIO'S

Granite Aggregate Production for Road Base, LagosIbadan Expressway Project

| Uitdaging: Required consistent, highvolume supply of certified ¾” down granite aggregate under tight deadlines, with zero tolerance for unscheduled plant stoppages.
| Oplossing: Implementering van 'n sleutel quarry plant featuring a robust primary jaw crusher, two secondary cone crushers in closed circuit with screening decks.
| Resultate: Behaal volgehoue ​​uitset van 280 TPH; met all material specification requirements; recorded 94% plant availability over the project’s duration.

Lateriet & Hard Rock Processing for Concrete Block Manufacturers

| Uitdaging: A block manufacturer sourcing mixed laterite and granite needed reliable onsite processing to control aggregate quality and reduce dependence on external suppliers.
| Oplossing: Installation of a midcapacity quarry plant with a versatile impact crusher capable of handling both softer laterite and harder rock fractions.
| Resultate:Gained full control over feedstock grading; reduced aggregate acquisition costs by an estimated25%; improved final block compressive strength consistency.
