Product Specification: A Critical Factor in Crushing Plant Design for Commercial Aggregate Quarries
(2018) Abdulraman S.O.; Olaleye B.M
Commercial quarries require prompt patronage for a better cash flow that will satisfy the prime objective of their establishment. Fonds and Pricey quarry is a 250T/H capacity quarry in Abuja and one of the many Nigerian quarries facing challenges of poor cash flow due to low sales with huge stockpiles of untradeable products. This unpleasant situation threatens the viability of a quarry business. This paper reviewed the production process and financial situation of F & P quarry with the view to revitalize the business through crushing plant process re-engineering to boost the quarry’s cash flow. Pareto analysis of the product sales was carried out and the complete sand making plant that would be amalgamated with the main crushing plant presented. This study showed that, most crushing plant designs give little or no consideration to crushed products demand and supply gap analysis; and there is a regional difference in the market potential for various quarry products, especially dust and 1/2”materials. A short and long term (models I and II) solutions were herein provided for old quarries facing similar business challenges and an improved crushing plant flow line for newly proposed aggregate quarries in Abuja that will guarantee better cash flow and consequent quick payback.
