The modular CX Trough Screw Conveyor system is highly versatile. CX Screw Conveyors are manufactured in stainless steel with a suitable surface finishing grade appropriate for the application. The fabrication of the troughs is carried out on machines that guarantee perfectly smooth surfaces due to which material residue is reduced to the minimum. CX Trough Screw Conveyors are made up from a U or V-shaped trough that is equipped with at least one outlet spout, an end plate at each trough end, helicoid screw flighting welded on a centre pipe with a coupling bush at each end, two end bearing assemblies complete with adjustable shaft sealing unit, a number of intermediate hanger bearings depending on the overall length of the screw conveyor, and bolted trough covers. Furthermore, CX Trough Screw Conveyors are equipped with a gear motor that suits the application. Depending on the material to be handled CX Trough Screw Conveyors come in a light or medium-heavy-duty design. Both types are available with ATEX, zone 22 certification.

Performance and Technical Features:
• Standard design in 304 L or 316 L stainless steel
• Troughs and screws in modular lengths
• Polygonal or cylindrical inlet and outlet spouts according to WAM® standard
• End bearing assemblies with externally adjustable shaft seals (stuffing box, air or gas-purged, others)
• Wide range of intermediate hanger bearings appropriate for the application (also self-lubricating)
• End flanges welded orthogonally on the trough on special jigs
• End plates carrying flanged end bearing assemblies and closing off the trough
• Modular length helicoid screw flighting with square or variable pitch welded on centre pipe with shaft coupling each end
• Screw sections connected by splined or bolted shaft couplings
• Screws accurately balanced
• Bearing assemblies entirely designed by WAM® to offer the right product for each application
• Perfectly smooth troughs for minimum material residue
 • WAM® drive units with integrated end bearing assembly and adjustable shaft sealing unit (screws run perfectly balanced due to drive unit directly mounted on screw pipe; substitutes coupling or chain transmission with special drive mount)
