EnviroConvey

Shaftless screw conveyor

The shaftless screw conveyors Enviroscrew are designed for transferring difficult and non homogeneous products.
They are commonly used in sewage treatment plants at different places but also in many industrial applications such as food industry for example.
Solid waste can be discharged into a container or conditioned beforehand in a continuous plastic bagging unit.
The shaftless design allows to overcome most of the conveying constraints in relation to difficult products. Such technology gives possibility to manufacture conveyors in one piece up to 30 meters.
The shaftless screw conveyors Enviroscrew may be installed vertically.
Such configuration opens possibilities to transfer products to further treatments positionned at upper floors, or to reach higher level in confined areas.
