Working principle on screw conveyors

Screw conveyors’ working principle are divided into three types

(1)Push

(2)Centrifugal induction

(3)Gravity sliding

What is push type ?It refers to screw conveyors are used to transport mediums/materials  by screw flights and screw conveyors are at the bottom of hopper,tanks or silo or live bottom. Materials are filled full of screw conveyors. Materials are forced to undertake bigger static pressure.But each granule’s gravity is smaller than other forces ( such as screw push,friction,static pressure.

What is centrifugal induction? It is available for vertical screw conveyors and conveyors are steep slope. Its feature is that materials’ filling rate are between forces. During high rotation speed,materials’ are affected by larger centerifugal induction force than gravity and other foreign forces.

(4)What is Gravity sliding ?When screw conveyor’s rotation speed is low,materials are affected by gravity force which is larger than the centerifugal induction force. Materials are sliding down because of screw conveyor’s rotation.Then cause the axial displacement.Basically speaking,CX screw conveyor belongs to such type.www.wxconveyor.com
