ABSTRACT A screw conveyor composed of a plurality of modules mated end to end and of identical integrally molded construction. Each module is molded of a suitable plastic material and has integrally formed therewith a cylindrical body, a coaxially disposed tube within the body, and a web helically disposed between the coaxial tube and the cylindrical body. The module includes ends mateable with corre- sponding ends of like modules to provide a screw conveyor of intended length and which is rotatable as a single unitary structure. Each module may have a sheave integrally molded thereon for mating with a V-belt drive. Alternatively, the modules can be of open form each having a helical web molded on a central tube preferably having a non circular core and adapted for end to end mating with like modules to provide a screw conveyor of desired length. This open type of screw conveyor can be readily retrofitted to systems having conventional metal conveyor screws.
