Tubular Screw Conveyors

GoTo Stainless Steel Tubular Screw Conveyors

Hydroscrew Tubular screw conveyors offer:

- Standard carbon steel or stainless steel

- Modular tube and screw sections

- Circular standard inlet and outlet spouts welded on the trough orthogonally as to the screw conveyor axis

- End bearing assemblies with shaft, roller bearings and externally adjustable packing glands

- Intermediate hanger bearings engineered for minimum restriction and ease of maintenance

- No material residue thanks to perfectly smooth tube surface

- End flanges welded on high precision jigs

- Tube bolted end plates complete with laser-cut drillings to accommodate end bearing assemblies

- Screws made up of modular helicoid constant or variable pitch flights welded on internal quality pipes

- Screw sections connected through splined shaft couplings

- Screws electronically balanced on all standard screw conveyors

- Heavy-duty end bearing assemblies designed and manufactured to meet highest industrial standards

- Self-lubricating maintenance-free intermediate hanger bearing slide bushes

- Wide range of adjustable shaft seals with packing glands and purged

- Gear motors with incorporated shaft sealing unit (by mounting the slow shaft directly on the centre pipe, screw rotation is perfectly balanced without the need of any additional power transmission coupling).

Hydroscrew also supply bespoke screw conveyors to your designs or as a collaboration with our engineers.

As a specialised version of the modular TU Screw Conveyor System, ES Screw Conveyors are manufactured in carbon steel with a suitable surface finishing and powder coating. They are made up from a tubular trough that is equipped with at least one inlet and outlet spout, a welded flange at each tube end, helicoid screw flighting welded on a centre pipe with a coupling bush at each end, two end bearing assemblies complete with self-adjusting shaft sealing unit (one of the bearing assemblies incorporated in the drive unit), a number of intermediate hanger bearings depending on the overall length of the screw conveyor. Furthermore, ES Screw Conveyors are equipped with a gear motor that suits the application.
ES Screw Conveyors are of the medium-heavy-duty type.
ES Screw Conveyors are used for feeding or conveying of cement and filler dust in concrete batching plants, cold filler dust in asphalt mixing plants, as well as cement and similar materials in building materials processing plants.
