The screw feeder is mostly designed as a sealed pipeline with a certain inclination angle. Usually, it is an integrated silo conveying pipeline. After the material enters the silo, it flows into the spiral pipeline. The friction between the spiral blade in the pipe groove and the material itself, Under the combined action of the driving force of the subsequent incoming materials, the feeding work is completed in the specified direction.

Feeding advantages of screw feeder:

The screw feeder can convey particles, powders and some small bulk materials with good fluidity or better.

Compared with belt conveyors, the advantages of screw feeders are mainly reflected in excellent sealing, minimal waste, realization of larger inclination angles and less space occupation.

1.Screw feeder with good sealing performance

The conveying pipeline of the screw feeder is usually a sealed circular pipe, and the material is completely sealed to complete the feeding, especially for the powder material, there will be no large dust during the feeding process, and the material is scattered and wasted. For some food and medical materials In other words, the generation of secondary waste is also avoided.

2. 0-90° delivery angle selection

If the belt conveyor is used to transport the material, then when the inclination angle is too large, the conveying volume of the material will inevitably decline to a large extent, but the screw feeder uses the friction force of the material itself and the friction between the spiral blade and the material that enters later. The driving force is used for conveying, with more power and less slippage, so the screw feeder can better handle the problem of inclined conveying of materials.
