Bulk Material Handling Industrial Inclined Tubular Shafted Spiral
Screw Conveyor
Screw Feeder is one of the conveying equipment which is widely used
in the chemical industry, building materials, grain, and so on. It
is mainly used in transporting powdery, granulated, and the small
massive material.
Characteristics of Sprial screw conveyor
1. The structure is relatively simple and the cost is low;
2. Reliable work, simple maintenance and management;
3. The size is compact, the section size is small, the occupation
area is small;
4. It can realize sealed transportation, which is beneficial to the
transportation of materials that are easy to fly, hot and smelly,
and can reduce the pollution to the environment.
5. Easy to load and uninstall. The horizontal screw conveyor can be
loaded and unloaded at any point on its transmission line;
6. The unit energy consumption is large;
7. The material is easy to grind and wear in the process of
transportation, and the wear of spiral blade and material groove is
also more serious.
Application scope of Sprial screw conveyor
U-type screw conveyor is widely used in building materials,
metallurgy, chemical industry, machinery, light industry, grain and
food industry. U-type screw conveyor is suitable for conveying
powder Shaped, granular, small bulk materials, such as cement, fly
ash, grain, chemical fertilizer, mineral powder, sand, soda and so
on. U-shaped screw conveyor is not suitable for transporting
materials that are easy to deteriorate, sticky and easy to caking.
The working environment temperature of the conveyor is usually-20
°40 °, the temperature of the conveying material is generally 20
°80 °℃, the U-shaped screw conveyor is suitable for horizontal and
small inclination arrangement, and the inclination angle is not
more than 15 degrees. If the tilt angle is too large, the tubular
screw conveyor should be selected.
