What is screw conveyer ?

 

Date : 13th March,2019

 

Usually screw conveyer is called auger which is used to transport bulk materials by screw flights’ rotation along auger’s shell.

Screw conveyer is made up of main three parts :auger body +inlet & outlet + drive device,see form 1 as below :

 Drive device is consist of : motor,gearbox/gear reducer,coupling,baseplate.

 

Auger’s Trough

Auger’s trough is made of sheet metal plate,and it is divided into three types : U shape trough ,V shape trough and tubular shape trough.

 

The shape of trough is made as per customer’s requirements.

 

 For single shaft driving auger : The transporting length is less than 35m for U trough auger.

 For twin shafts driving auger: The transporting length is bigger than 35m for U trough auger.

Form 3

Name

Single shaft driving auger

Twin shafts driving auger

Tubular shell has better sealing than U trough structure. So people often called the tubular auger by sealing auger.The clearance between trough and screw flights are determined by friction between screw diameter and materials.www.wxconveyor.com
