A B&W, heavy duty, 800 series StormajorTM radial boom loader has been supplied in record time to the Poznan based company, Strateg Capital for its mining operation located in Tłumaczów in Poland. The Stormajor will be used to load Melaphyre rock into open top rail-cars. Strateg Capital will produce over 40 Mt of the basalt like material from the mine. It embarked upon a ‘fast-track’ mine development earlier this year which generated an urgent requirement to install a rail-loading facility.
The equipment was needed within 13 weeks. This short time-frame, together with the requirement for very robust equipment, led the customer to seek a solution from the well-known supplier of mobile port loading and unloading equipment, B&W Mechanical Handling in the UK. B&W is fully integrated into the International Aumund Group with strategically placed offices in more than 10 countries and representatives in over 40.
The Stormajor combines the benefits of the well known Samson feeder design with a radial slew and luffing outloading boom conveyor into a single mobile machine, able to receive material both from trucks and loading shovels. At Tłumaczów the equipment is designed to receive rock with a bulk density 1.6 t/m3, from 30 t capacity Terex TA30 articulated dump trucks. However, in a second phase of the project the trucks will be replaced by mobile link conveyors which will feed the material into the Stormajor through a specially designed feed hopper.
The Stormajor, designed for a maximum throughput of 600 t/h, is equipped with a 15 m outloading boom and loads directly into rail-cars up to a height of 5.0 m. The outloading boom is able to be slewed plus or minus 30o and luffed from zero to 30o providing great flexibility and the discharge is fitted with a variable angle trimming chute which aids even-loading. Initially the Stormajor will be towed alongside the rail-cars to facilitate loading but once the mobile link conveyors are installed the unit will remain mostly static and the rail-cars will be locomotive hauled.
The unit needs only one 400 V supply to the on-board 110 kW hydraulic power pack which drives the belt, slewing and luffing operations. The unit is mounted on rubber tyres for easy towable relocation.
