1. PAINPOINT DRIVEN OPENING

Managing an ODM quarry site in Lagos presents distinct operational hurdles that directly impact profitability. Are you contending with inconsistent material quality from subcontractors, leading to rejected loads and project delays? Are production bottlenecks and equipment downtime causing you to miss critical delivery windows in a competitive market? Is the logistical complexity of coordinating multiple smallscale operators eroding your margins through inefficiency and quality control overhead? These challenges translate into quantifiable costs: lost revenue from idle plant assets, penalties for late deliveries, and the recurring expense of remedying substandard aggregate. The central question for commercial operators is this: how can you consolidate control, guarantee output specification, and drive predictable, scalable production on your site?

2. PRODUCT OVERVIEW

This content outlines the strategic implementation of a dedicated, owneroperated quarry processing plant for ODM (Owner Developed Material) sites in Lagos. This solution transitions operations from reliance on disparate contractors to integrated, controlled production. The core operational workflow involves: (1) controlled feeding of raw feed (granite, limestone) via a regulated system; (2) primary crushing to a manageable size; (3) secondary and tertiary crushing for precise gradation; (4) screening to exact specification fractions; and (5) stockpiling of certified aggregate. This model is specifically scoped for mediumtolarge scale ODM projects requiring consistent, highvolume output of constructiongrade aggregate (e.g., ¾”, ½”, ¾ down). It is less suited for very small, shortduration sites where simple crusher rental may be more economical.
