Screw Conveyor For Powder Material In Mining Industry
1.Screw conveyor Usage and application:
It is applied to convey loose materials such as powder, granular and small piece material, such as clay powder, pulverized coal, cement, sand, grain, small piece of coal, cobble, and cast iron filings, etc.
2.Working principle of screw conveyor
The material feed into the casing and screw flight was hold back by the frication resistance acted on the wall of casing during running, the screw flight push the material and make the material do axial movement, simultaneity the clockwise and counterclockwise fight act as mixer. The material can be discharged at the proper outlet at the bottom of casing or transport out at the end of chute. Conveyor with simple construction, be able to feed and discharge in many position, it is easy to operate, have good seal capability and environmental friendly.
3.screw conveyor features:
1. Large carrying capacity, safe and reliable.
2. Strong adaptability, convenient installation and maintenance, long service life.
3. Small size, high speed, ensure fast and uniform delivery.
4. The discharging end is equipped with a cleaning device, with low noise, strong adaptability and flexible location of the inlet and outlet.
5. Good sealing, the shell is made of seamless steel tube, the end is connected with flange, good rigidity.
