Sideshifting screws consist of a large-diameter, robust screw rotating around its axis and whose rotating supports are mounted on sideshifting carriages linked to racks.
The sideshifting screw is mounted in the lower part of a flat-bottomed feeder hopper with a rectangular cross-section.
The rack system allows the sideshifting screw to travel the length of the storage hopper at will.
Sideshifting screws make it possible to store bulk materials such as lime, limestone, coke, sand and sawdust in large parks, so that once these products have been unloaded from the transport vehicles they do not require further handling by the operator.
A double inverter system for the regulation of the speed of rotation and the feed of the screw conveyor allows the extraction capacity of the material to be adjusted at will, so that the sideshifting screw conveyor can also be used as a storage system upstream of a grinding or transport unit.
In addition, the distinctive profile of the hopper makes it possible to equip the storage unit with an effective dedusting device both during the unloading of the vehicles and during the extraction phase.
