Proportioning and conveying screws
in modular design
The conveying screws serve for
continuous transport of bulk material
in horizontal or ascending direction.
The simple design and low
maintenance requirements of the
conveying screws contribute to their
high operational reliability. The screw
troughs with removeable covers are
executed in a stable construction.
The troughs, in the standard lengths of
1500, 2000, 2500, 3000 mm, are
connected with each other by means
of flanges. Special trough lengths are
available.
The worm shaft consists of a tubular
shaft with welded-on solid thread
made of sheet steel. It runs on
antifriction bearings with stuffing box
sealings. In case of larger lengths
maintenancefree intermediate bearings
are used.
The tubular shaft parts are connected
by means of bolts. The inlets and
outlets can be arranged according to
requirement.
The screws are driven by offset geared
motors. If sufficient space is lacking,
other drive types are possible, too.
Designs:
■ Controllable proportioning screws
■ Conveying screws
■ Thread types: solid blade thread,
belt thread, paddle thread
