Screw Conveyors

GEA Screw Conveyors are available in a wide range of styles for general conveying applications as well as for silo discharge duties.

Single units with variable pitch augers or multiple auger units for difficult products may be used to assist the discharge of materials with poor flow properties from silos. Primary considerations for the selection of a screw conveyor are: Type and condition of the material to be handled, including maximum particle size, and the bulk density of the material to be conveyed. Quantity of transported material, expressed in pounds or tons per hour. The distance for which the material is to be conveyed.
