| 1 | Crushing Plant Performance Evaluation Using OEE |
Over the years, economy of scale has been adopted as a panacea to the poor return on investment (ROI) in aggregate quarry establishments. This has forced quarries to increase their capital expenditure (CAPEX) due to acquisition of large capacity equipment that are often very costly. Low commodity (chippings) prices and high energy costs have further compelled quarry operators to adopt cost effective operating strategy. The true cost effectiveness of aggregate quarries lies in their performances and life cycle costs, of which their performances depend on their equipment availability; utilization and efficiency. Quarry equipment availability, utilization and efficiency are therefore very important performance indices that a quarry operator needs to constantly evaluate to work within the threshold, if the quarry business must deliver high ROI or quick payback which ultimately is the prime objective of any business. Overall Equipment Effectiveness (OEE) is a well-known performance metric which combines availability, utilization and efficiency for the evaluation of crushing plant effectiveness in an aggregate quarry. The performance metrics of F and P quarry, Abuja, Nigeria have been determined, and the plant availability (A); utilization (U); efficiency (E); and OEE evaluated to be 77.55%, 65.08%, 33.15%, and 16.62% respectively. The OEE value is far below the global best standard of 85% for manufacturing system, and reflects the influence of plant availability, utilization and efficiency on OEE value. However, there is no literature on the use of OEE for granite crushing plant, though; attempts have been made to use the metric on drilling machines, loading and haulage facilities. This paper presents a procedure for estimating OEE of a crushing plant; explains the cause for poor OEE in Nigerian plants during rainy season; and reason why Nigerian crushing plants should run with generators of adequate power outputs; and not on external power source. | Abdulraman S.
