Screw Conveyor

Brief Description

The Shaftless Screw(Spiral)Conveyor is an alternative concept to the traditional shafted screw conveyor. Material is conveyed by an extra-heavy-duty shaftless screw that slides on a low-friction, wear-resistant liner inside the conveyor trough housing.

The Shaftless Screw (spiral) offers a larger volume capacity and the possibility of handling particularly difficult materials such as those that tend to become tangled up or those that present highly variable particle size. Construction material properties, oversize thickness, as well as a special manufacturing process make the spiral highly resistant and extremely durable. Due to the absence of intermediate bearings, obstacle-free material handling is guaranteed. The completely enclosed trough prevents any material leakage. Trough covers with appropriate gaskets enable odour-free operation and form a barrier to any atmospheric agents to enter the system. At the same time the conveyor offers maximum access to the inside for inspection and cleaning. Maintenance is reduced to the minimum due to a small number of components. There is a vast choice of liners depending on specific material characteristics.

Feature & Benefits

1.One of the main reason to use a shaftless conveyor is the ability to handle different type of material. Shaftless screw conveyors can convey stingy, sticky, wet, and lumpy materials.

2.Without the need for hanger bearings a shaftless conveyor can have a higher fill rate at closer to 35%-40%. For applications such as live bottom hoppers, and metered feed, it is possible to run a shaftless screw conveyor at 100%.

3.Shaftless screw conveyors are ideal for pulling vertical conveyors since there is not a bottom shaft or seal.

Application

Shaftless Screw (Spiral) Conveyors are specially designed for handling difficult, heterogeneous materials such as urban solid waste, screenings and floating matter, de-watered, thickened, conditioned sludge, packaged food, creams or pastes, as well as waste from: meat, fish, fruit and vegetable processing. The main sectors of application are: wastewater treatment, sugarhouse rejects, fish industry, solid waste treatment, fruit and vegetable processing, beverage industry, pulp and paper, chemicals, food industry in general, meat processing plants, abattoirs/ slaughterhouses, restaurants, canteens, catering in general.
