Contact All Suppliers Feed Screws

Feed screws use a rotating helical screw blade to move a conveyor carrying liquid or granular materials. They are used frequently in industries where bulk handling is used regularly. They are mostly used horizontally or or at a slight incline as an efficient way of moving semi-solid materials. Some examples of these are food waste, wood chips, aggregates, grains, animal feeb, boiler ash and many others. It is based on the old Archimedes screw that was used in the ancient times to pump water. They usually consist of a tube that contains either a spiral blade coiled around a shaft that is driven at one end and held at the other.
