  • Mt Bundey Quarry Crusher Optimisation Project 2016

    Scope: • The objective was to achieve a 10% improvement in average plant throughput by optimising the crushing circuit: • Increase FCR throughput from 278t/hr to 306t/hr. • Increase aggregate throughput from 262t/hr to 288t/hr. • It was estimated that a 10% improvement in production would reduce costs by >$309k/annum.
