Abstract
A screw conveyor for loose material comprises a tubular casing having a first part which is axially rotatable on command with respect to a second part. The first part is provided with openings through which the material can be introduced into the casing. A screw, internal of and coaxial to the casing, can rotate on command about its own axis and thus convey the material. A helical conveyor device which is solid in rotation with said first part of the casing, conveys the material towards the openings in first part of the casing. There is a hollow jacket between the conveyor device and the second part of the casing, through which the material passes. The invention provides greater efficiency in collecting and removing loose material from a pile.
