We designed an economically complete system made of several belt conveyors. In addition, we supplied a system control (PLC), transfer stations and filter systems as well as foreign material separators. The system is dimensioned for a conveying capacity of 2,200 tons per hour. The core of the conveying system for limestone consists of two belt conveyors leading downwards, which are run in regenerative mode and are followed by a troughed belt conveyor with horizontal curves. The material is transported from the crusher discharge conveyor to the first two troughed belt conveyors. Afterwards, the material transported is transferred via an acceleration belt conveyor to an overland conveyor with a centre distance of 3,464 metres at a speed of four metres per second. The conveyor is equipped with vertical and horizontal curves and achieves a speed of 4.5 metres per second. Three following conveyors transport the material to the blending bed.
In order to remove the material from the blending bed and to feed the primary hopper of the raw mills, we supplied further belt conveying systems with an overall length of 989 metres. We were able to build and install all the conveyors in only eleven months. The commissioning phase of three months was followed by the performance tests. Finally we handed over the complete system to the customer. That was in 2015, but the project was not yet terminated for us.
