Flexible screw conveyor is a flexible helix as a carrying member, directly driven by the motor rotation (or via speed reducer drive) and conveying material, suitable for conveying powder, granular, spherical and flake material. The screw conveyor can be used as a straight line, and also can be bent and conveyed, which makes it easy for the user to arrange all kinds of equipment. Flexible helix is the only moving part of the conveyor, no matter how far distance transportation, transportation without other moving parts bearing tube, so the conveyor reliable performance, almost no maintenance, does not occur as bearing grease pollution materials of this kind of problem. Another notable feature of the flexible screw conveyor is easy to clean, a person can only 5 minutes to the disintegration of the conveyor, cleaning work. Single curved screw conveyor conveying material, the vertical height of up to 10 meters, the horizontal distance of up to 25 meters. If the multiple conveyor in tandem, it can be transported farther, higher distance.
