There are many feeding devices, and different types of feeding devices have different characteristics. So, what are the characteristics of the screw feeding device, and in which fields is it applicable?
Screw conveyor is a widely used powder and granular material conveying equipment. It adopts tubular screw, which can be conveyed horizontally and inclined. The inclination angle can be selected arbitrarily from 0° to 90°. The general inclination is 45°. The following is better, and the length is less than 5m without adding hanger bearings in the middle, and the longest is not more than 6m.
When the screw rotates, the material added to the tank cannot rotate with the screw surface due to its own gravity, but it is pushed forward by the rotation of the screw, just like the nut on the bolt, it moves forward in a straight line and plays a role of conveying. Purpose. The screw conveyor is generally composed of a hopper, a casing, a shaft and blades mounted on the shaft.
There are generally three observation ports on the shell, upper, middle and lower, and the lower part is provided with a discharge port.
The screw conveyor adopts unequal-distance screw to overcome the material blocking phenomenon. The discharge port is equipped with a discharge plate, which prevents the material from being transported into the bearing. The material is all made of stainless steel, which solves the corrosion problem of ammonium nitrate.
