Star shaped unloaders are the main equipment for dust removal, air supply, and other equipment feeding. The unloaders are mainly divided into two shapes: A-type square mouth unloaders and B-type round mouth unloaders, and can also be divided into three categories: ordinary type, pressure resistant type, and high temperature resistant type. The unloader can be driven at a constant speed to continuously discharge materials at a controlled rate, or it can be driven at an indefinite speed and used as a feeder. The star shaped unloader is suitable for both powdered and granular materials.

The several prominent features of the star shaped unloader are as follows:

1、 Star shaped unloaders can be used in material collection systems as unloaders for silos. It is particularly suitable for dust and small particle materials, and is widely used in engineering projects in industries such as environmental protection, metallurgy, chemical engineering, grain, cement, road construction, and drying equipment.

2、 When the material in the upper silo falls by its own weight and fills the gaps between the blades, it is discharged from the lower part as the blades rotate. Therefore, the star shaped unloader can discharge in a quantitative and continuous manner.

3、 Star shaped unloaders can be used in material collection systems as unloaders for silos. Currently, star shaped unloaders are the most common unloading devices and are commonly used as important equipment in dust removal systems. They are particularly suitable for engineering projects in industries such as dust, small particle materials, environmental protection, metallurgy, chemical engineering, grain, cement, road construction, and drying equipment.

4、 The temperature resistant type can transport materials with a temperature of up to 280 ° C. The bearings at both ends are isolated from the impeller to prevent powder from coming into contact with the bearings. The high-temperature resistant unloader can transport materials at a temperature of up to 500 ° C and is connected by chain wheels. There is a certain distance between the reducer and the unloader housing. The structure of a star shaped unloader is usually composed of a rotor impeller with several blades, a housing, seals, a reducer, an electric motor, etc. The star shaped unloader is also known as a rotary feeder, a lock valve, a star shaped ash discharge valve, a star shaped unloader, a damper, etc.

5、 Star shaped unloaders are commonly used in pneumatic output systems. For pressure output systems or negative pressure output systems, star shaped unloaders can uniformly and continuously supply material to the conveying pipe. To ensure the stability of the gas and solid in the pneumatic output pipe, so that the pneumatic conveying can work normally, and at the same time, it can also block the upper and lower air pressure of the unloader and play a role in air locking. Therefore, the star shaped unloader is an important component commonly used in pneumatic conveying systems.
