1. PAINPOINT DRIVEN OPENING

Are you managing a premium quarry site in Lagos and facing persistent bottlenecks that erode profitability? The challenges of operating in this demanding environment are specific and costly. Inconsistent feed material from the face can choke your primary crusher, leading to hours of unplanned downtime for clearing. The abrasive nature of Lagos granite and sharp aggregate wears down standard equipment at an accelerated rate, forcing premature component replacement. Furthermore, inefficient separation processes result in product contamination, downgrading material to lowervalue grades and directly impacting revenue per ton. Dust suppression remains a critical operational and regulatory hurdle, with inadequate systems risking site shutdowns. Are these issues causing your plant’s actual output to fall consistently below its nameplate capacity? The solution lies not just in machinery, but in precisionengineered equipment designed for the specific rigors of a premium Lagos quarry.

2. PRODUCT OVERVIEW

This content details our engineered Premium Quarry Sites In Lagos solutions, specifically focusing on highcapacity, trackmounted primary crushing and screening plants. These units are designed for direct feed from large excavators at the quarry face.

Operational Workflow:
1. Direct Face Feeding: A large excavator loads blasted rock directly into the plant’s oversized hopper.
2. Primary Crushing & Prescreening: An aggressive jaw crusher reduces material, with an integrated prescreen removing fines to bypass the crusher, increasing throughput and reducing wear.
3. Primary Product Separation: Crushed material is conveyed to a highoutput primary screen for precise separation into required aggregate fractions (e.g., 05mm, 510mm, 1020mm).
4. Stockpiling or Secondary Processing: Onspec material is conveyed to stockpiles via radial conveyors, while oversize can be recirculated or sent to a secondary crushing circuit.

Application Scope & Limitations:
Scope: Ideal for medium to largescale granite, limestone, and laterite quarrying operations in SouthWest Nigeria requiring production of 200600+ tons per hour of highspecification aggregate.
Limitations: Not suitable for smallscale or highly mobile operations due to initial investment and setup requirements. Optimal performance requires competent operator training and planned maintenance adherence.
