Screw conveyor type-E

Our screw conveyors are manufactured as standard in stainless steel, reducing corrosion and maintenance. The material selection can be customized to withstand wear, heat, and various types of conveyed goods.

At Autofric, we have been manufacturing spirals since 1984, and our extensive experience forms the foundation for the development of the shaftless screw conveyor Type-E. The unique design, with a trough featuring folded edges that surrounds the spiral, minimizes material rotation and increases forward movement.

The Type-E offers high energy efficiency and supports both horizontal and vertical transport. With flexible solutions for inlets, outlets, and transitions, it is suitable for a wide range of applications.

Tube troughs are primarily used for feeding and lighter materials, with options for inspection hatches. For outdoor installations, the conveyor can be equipped with frost protection and insulation. Depending on the material, either shaftless or shafted spirals are used.

What are screw and spiral conveyors used for?

• Loading and lifting: Efficiently distribute bulk materials to different locations using multiple inlet and outlet points.
• Feeders: Can be configured as screw feeders to control material flow in processes that require precise dosing, such as automated feeding systems.
• Mixing products: A screw conveyor can be used as a mixer or agitator to blend dry or liquid ingredients.
• Heating/Cooling: Suitable for various materials.
• Drying: For different types of materials.

Areas of application

• Pulp and paper industry: Knots, pulp, fiber sludge, wood chips, bark, sand.
• Biomass combustion: Pellets, wood chips, sawdust, peat, bark, wood flour, coal, coal dust, fly ash and bottom ash.
