Preparation of screw conveyors shaft

Preparation of screw conveyors shaft

 

Bending shaft of the screw conveyer after welding, assembling the blades of the conveyer (flight) into shaft of the screw conveyer is a very important step. To reduce vibrating during running and increase the service life of the screw conveyer.

 

After welding, the screw conveyer blade to the shaft of the conveyer screw, often causing the shaft of the conveyer to bend or deflate. It is therefore necessary to bend the shaft of the screw conveyer. Before using the shaft of the finished screw conveyer to use

 

Bending of the conveyer screw shaft is done in several ways. But that we often use 2 methods Is bending by mechanical method (using a hydraulic jack) or bending by heat method (welding or using a gas nozzle).

 

The allowable deflection we use is no more than 1.5 mm per the shaft of the screw conveyer length 3 m.
