Screw conveyor for transporting powdered material, has rotation speed control provided with programmable controlling unit for controlling rotation speed of motor based on determined rotating position of screw within complete screw rotation

摘要

#CMT# #/CMT# The screw conveyor (1) has a rotatably supported conveying screw (3) for transporting material from a storage container (2) to a discharge opening (6). A motor (4) with variable rotation speed is provided for a drive of the screw. A rotation speed control is provided with a programmable controlling unit (7) for controlling the rotation speed of the motor based on the determined rotating position of the screw within a complete screw rotation. The rotation speed control is controlled based on the quantity of the material and/or the pre-selected inclination angle of the conveying screw. #CMT#USE : #/CMT# Used for transporting powdered material. #CMT#ADVANTAGE : #/CMT# The screw conveyor is designed in such a manner that it avoids the periodic fluctuations arising during the material flow and the restrictions regarding the inclination position. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a horizontal position of a conveyor screw. 1 : Screw conveyor 2 : Storage container 3 : Conveying screw 4 : Motor 6 : Discharge opening 7 : Programmable controlling unit.
