UV-LXWZ Shaftless Screw Conveyors are devices that can transport large amounts of different materials. They can handle materials that are hard to move, such as urban solid waste, sludge, food waste, and more. They are useful for many industries that deal with these kinds of materials, such as waste water treatment, sugar production, fish processing, fruit and vegetable processing, beverage production, pulp and paper, chemical industry, food industry, meat industry, and catering services.
The UVWZ shaftless screw conveyor presents an innovative approach compared to traditional shafted screw conveyors. It offers a range of diameters from 6” to 24” in single flight and 9” to 24” in double flight configurations. Material is efficiently conveyed by a heavy-duty shaftless screw that moves on a wear-resistant liner within the conveyor trough housing. The U-troughs are crafted from carbon steel or 304 L / 316 L stainless steel, with appropriate surface treatments. The lower part of the trough features a fitted liner, while one end of the trough includes a standard bottom discharge or open end outlet. At the drive end, the screw conveyor is equipped with an end plate holding the end bearing assembly with a flanged shaft coupling. The drive unit is tailored to suit specific applications.Loading options for the UVWZ include loading from above into the open trough (standard), through an inlet spout in a bolted trough cover (optional), or from the side through a special side inlet in the loading zone of the trough (optional)
The design of shaftless screw conveyors like the UVWZ enhances efficiency by eliminating clogging issues and providing flexibility in plant layout configurations. These conveyors are ideal for handling various materials, including those with high moisture content, offering improved conveying efficiency compared to other types of conveyors Additionally, shaftless screw conveyors are widely used across industries such as wastewater treatment, food processing, mining, and agriculture due to their ability to handle different materials effectively
The Shaftless Screw Conveyor, exemplified by the UVWZ model, boasts several advantageous features. Its design facilitates the handling of challenging materials, including those prone to entanglement or with varying particle sizes. Constructed with robust properties, such as oversize thickness and a specialized manufacturing process, the spiral is exceptionally durable.
The absence of intermediate bearings ensures obstruction-free material handling, while the fully enclosed trough prevents any material leakage. Trough covers equipped with suitable gaskets not only enable odor-free operation but also act as a barrier against contaminants entering the system. This design consideration also provides maximum access to the interior for inspection and cleaning purposes.
With a minimal number of components, maintenance is significantly reduced. The conveyor offers a wide range of liners to accommodate specific material characteristics. The UVWZ Shaftless Screw Conveyors are specifically tailored for handling challenging heterogeneous materials such as urban solid waste, screenings, floating matter, de-watered sludge, and various processed food wastes.
These conveyors have proven successful in transporting dry abrasive products like cement, sand, and abrasive dusts. They find application across diverse sectors, including wastewater treatment, sugar mills, fish and meat processing industries, solid waste treatment, beverage production, cement packaging and mills, dust collection, pulp and paper, chemical industry, and general food processing. Whether in rendering plants, slaughterhouses, restaurants, or catering establishments, the UVWZ Shaftless Screw Conveyor stands out for its efficiency and versatility.
