Nordberg MP1000 versus 2 m (7 ft) SHD Symons cone crusher: Performance comparison

Based on extensive investigations on the effect of design variables on process performance from 1982-85, Nordberg developed a 746 kW (1000 hp) cone crusher with the objective of boosting crushing productivity in existing plants. The MP1000 fits on the same foundation as the 2 m (7 ft) SHD Symons cone but is designed to give two times the capacity of the 2 m (7ft) The economies of scale involved give the customer substantial cost savings. In this paper, process performance of the Nordberg MP1000 relative to the 2 m (7 ft)SHD Symons cone while crushing the same ore, will be presented. Also, implications of such a crusher scale-up to associated cost savings will be addressed.
