Saxlund have a long history and experience in the design and construction of
screw conveyors. Today we manufacture four main types:Standard SAX
ScrewsThese are shafted with flights fully welded to this shaft and no hanger
bearings. These screws are used for all general applications and up to 10 m
in length and 1000 mm in diameter. Flights can be any steel type according to
the application. When stuffing boxes are fitted, the shaft always has an
adjacent wear sleeve. Drives can be with chain wheels, shaft mounted or
direct driven to clients request. Construction can be in mild steel or
stainless.Shaft-less ScrewsThese are generally used for screws longer than
10 m and have their casing manufactured in 304 stainless steel. The casing is
always lined with UHMWPE plastic material and they are driven by shaft
mounted gear motors. Systems with vertical screw conveyors can be
supplied.Ribbon ScrewsThese are generally used for special cases where the
conveyed material is very sticky and may otherwise cause 'logging' in a
standard screw. We use our ribbon screws for example in our ash
conditioning mixer.
