Function

Transport of aggregates from pit to existing silo.

A fixed receiving hopper is emptied by vibrating feeder on subsequent belt, which in turn conveys the material to a stacker that places the material on stockpile. The stacker is designed with a mast construction which allows a large overhang measured from final support point.

A ground tunnel is located at the bottom of the buffer stock which can be emptied automatically by means of two roof-mounted vibrating feeders. A partially roof-mounted conveyor conveys the material onward out of the tunnel to subsequent conveyor which conveys the material to existing silo that constitutes the delivery boundary.

There is a large height difference between loading point and unloading point, which places high requirements on design and optimisation in order to meet local topographic conditions in this project.
