Structure and Functioning


Conveyor consists of drive section 1 (fig.1), intermediate section 2, end section 3, drive 4, screw drive shaft 5, screw intermediate shaft 6, screw end shaft 7, intermediate supports 8, bearing blocks 9 and 10. Conveyor sections may be in the form of trough (horizontal or inclined max. to 30º transportation) or tube (inclined above 30º). Bushings, which do not require periodic lubrication, are applied as intermediate supports. Bushing can be made of polyamide or oak boiled in oil. Conveyor drive may be in the form of chain transmission (fig.2) or gear motor. In the version with gear motor, transmission of rotational moment to conveyor shaft is provided by installation of coupling designed by manufacturer.


Conveyor operation process is as follows: product is supplied through loading pipe and moved by rotating screw shafts for discharge to unloading pipe. It is recommended to start up the conveyor without product inside and stop only after full product unloading.
