Screw conveyors are divided into shaft type and shaftless type. The screw conveyor with shaft is suitable for non-sticky dry powder materials and small particle materials (such as: cement, fly ash, lime, grain, etc.). While the shaftless screw conveyor is suitable for conveying viscous materials. No risk of clogging due to material sticking to the shaft (eg: sludge, pulp, biomass, garbage, etc.), the use of fully enclosed conveying and easy-to-clean helical surfaces guarantees a hygienic environment and ensures that the delivered material is not contaminated and not leaked.

Characteristics

1. Uniform conveying, no material jamming: the speed of the whole machine is fast, the conveying is fast and uniform, the material is not easy to be blocked, and it can be connected and fixed with other equipment.

2. Sealed construction: keeps out odors, keeps foreign objects out, avoids spills and minimizes maintenance.

3. Easy to load and unload: the horizontal screw conveyor can be loaded and unloaded at any point on its conveying line, and the vertical screw conveyor has superior feeding capacity compared with the screw feeding device.

4. Flexible layout: it can be erected on a raised shelf, on the ground or in a pit, can be installed horizontally or on a slope (≤15°), and can also be transported vertically.
