Use the best quality to fabricate ,combine the suitbale technology and machining equipment; 2. Make inspection before delivery. Do not deliver any goods if there exist some defects.
2. What is the conveying principle on vertical screw conveyor and big incline degree screw conveyor ?
Vertical or incline screw conveyor ,or screw conveyor with high speed,its working principle are : due to materials are between two mediums,with high rotation speed,the bulk materials get larger centrifugal force than its gravity and other foreign force.Then convey materials by centrifugal force. This working principle is also called centrifugal induction.www.wxconveyor.com
