A screw conveyor is a mechanism that uses a rotating helical screw that is installed within a tube or trough, to make liquid or granular materials. Screw Conveyors are an excellent choice for the transfer of materials from one point to another. They are used for carrying away screened material, grit, dewatered sludge or such other materials to be disposed of in water and wastewater treatment plants. They can be installed horizontally or inclined to depend on the design requirements. Our supplied screw conveyor systems are designed to meet and surpass all application requirements, are very cost-effective and require minimal maintenance to operate.
Screw Conveyors with Shaft –This range has been built by a screw with a central shaft which is directly connected to the drive unit from one side and to the bearing from the other side. They are suitable for the transportation of solid and semi-solid materials. Screw conveyors with shaft move a wide variety of material from bins or hoppers at a constant and controlled rate of flow. One or more tapered or variable pitch screws convey the material at the required rate. Screw conveyors are available in a variety of types to suit specific materials and applications.
Shaftless Screw Conveyors –Shaftless screw conveyors are built by a shaftless screw which is placed on a polyethylene coating inside of a trough, with inlet hopper and outlet chutes. These are used in applications where particle sizes are large and do not require hanger bearings because there is no center pipe. The shaftless screw conveyors eliminate the central shaft and allow a much higher fill rate resulting in lower rpm’s, more efficient conveying and consequently less wear. The transportation of the sticky materials is allowed due to the lack of a shaft which is generally difficult to transport by the screw conveyors with the shaft. No intermediate or end bearings are required without a shaft, the trough liner is the spiral’s replaceable bearing surface. The only machined bearings in a shaftless are present in the gear reducer. This allows for direct connections and optimizes layout design flexibility. End-to-end and side connections not possible on shafted screw conveyors are common solutions available in the shaftless design. The bottom of the trough where the shaftless screw is placed inside is protected by a wear-resistant coating in HDPE (High-Density Polyethylene). Dutco Tennant LLC supplies screw conveyors which are mainly made up of inlet hopper, outlet chute, trough, screw, shaft, support legs and drive unit.
