Introduction of Screw Conveyor
Screw conveyors, also known as auger conveyor,Spiral Conveyor, are made for simple conveying duties applications. The real strength of our company, however, is our ability to produce individually designed units that include features to overcome awkward installations, materials that are difficult to handle, or include performance or process functions beyond simple conveying. Some requirements may be concerned with aspects of hygiene, others with bulk solids that have poor or delicate conveying properties.
Screw conveyor is divided in two types rigid screw conveyor and shaftless screw conveyor.
Rigid screw conveyor is suitable for non-sticky powder and small particle material such as cement, fly ash, lime, flour, starch, food additive etc.
Shaftless screw conveyor is suitable for sticky and easy winding materials such as sludge, biomass.
