Design Features of Screw Converyor

Summary：

Screw type conveyor (screw elevator) is a kind of conveying machine which is commonly used in all kinds of lifting conveying equipment, so manufacturers will pay more attention to make it works steadly.

1. Reduce the rise angle of helicoid

In order to make the screw conveyor has a better sealing, and avoid conveying materials to be pollut in the process of conveying. Screw conveyor manufacturers will try to reduce the critical speed of equipment, usually take measures to reduce the angle of helicoid and reduce the friction angle between material particles and the helicoid. In addition, the friction coefficient between material particles and shell wall will be appropriately increased.

2. Using special sliding sleeve structure

In order to avoid the hidden danger of the pollution of material, the manufacturers will take methods in designing and manufacturing of special sliding sleeve structure design. Because of the structure of the cross-sectional area is small, the running resistance will be reduced when the materials are lifed and transported. It not only can reduce power consumption, but also can improve the transport speed, so as to shorten the transport time of material.

3. Control the reasonable transmission power and outer diameter size

The transmission power of screw conveyor is not the greater the better, and in order to meet the requirements of sealing and transmission height, power consumption should also be reduced as far as possible. To this end, screw conveyor manufacturers will increase the torque of the transmission shaft when designing and manufacturing, and will also limit the size of the outer diameter of the screw to a certain extent, to avoid the sliding speed of material particles at the edge is too large.

The screw conveyor which is manufactured by QIANGHAN MACHINERY is widely used for the unloading operation of powder and particles. We sincerely provide customers with integrated services from scheme design, installation to technical training, maintenance and after-sales.
