The compact BWE system set up in 1984 to mine ironsand dunes and the underlying ironsand-clay has been an effective high volume produc- tion unit for New Zealand Steel Mining Ltd at the Waikato North Head ironsand mine. The system utilising two compact S400E (0 & K) Bucket Wheel Exca- vators and a single shared Beltwagon for transfer to the shiftable bench conveyors replaced a fleet of mobile elevating scrapers when the produc- tion requirement was increased by a factor of six. A key factor in favour of the BWE system was the economic advan- tages of low unit costs for both manpower and electrical energy.
