With the rapid development of economy, the modern market puts forward higher and higher requirements for transportation equipment. In the future, screw conveyor has become the development direction.

 Screw conveyor

Precautions for adjusting hopper inlet of screw conveyor:

1) the angle of the feed chute should be appropriate to avoid material blockage in front of the feed port. The slip angle of the sliding pipe is determined according to the characteristics of the material, the material and shape of the sliding pipe and the service conditions. Generally speaking, the sliding angle is 5 ° to 10 ° higher than the dynamic repose angle of the material. The material blocking the material, the material with less moisture and the material flowing by mechanical force can take a smaller value, while the material with large powder and moisture should have a large slip angle.

2) the loading mode of screw conveyor should be considered in the adjustment of feed inlet of screw conveyor, so as to ensure smooth feeding without increasing the resistance of hoist (mainly the resistance of lifting materials and material). There are two types of screw conveyors, lifting and inflow. Tensile type is mainly used for conveying powder, granular and small non abrasive or semi abrasive bulk materials. The hopper is usually sparsely arranged to allow the hopper to run at a higher speed because it does not create a lot of resistance when the material is stretched. The inflow type is used for conveying large abrasive materials. The hoppers are arranged intensively to prevent the materials from flying between the hoppers. The hopper runs at a lower speed.

 Principle of screw conveyor

Main features of screw conveyor:

1. The design principle and processing method ensure the reliability of the whole machine operation; the feeding, conveying and unloading forms of the traction machine cause small extrusion and collision between various parts of the hoist, and reduce mechanical wear. Therefore, the operation is smooth and a high lifting height can be obtained.

2. The service life of screw conveyor is long, and the fault free time is generally more than 20000 hours.

3. Screw conveyor adopts gravity feeding and gravity, centrifugal unloading, and dense layout of large capacity bucket. Therefore, it has the characteristics of high effective power and low driving power.

4. Screw conveyor has a wide range of applications, and requires less material types and characteristics. Not only can the high abrasive resistance of the general material be improved, but also the powder material can be improved. It has good sealing performance and almost no pollution.
