旋转的螺旋叶片将物料推移而进行螺旋输送机输送,使物料不与螺旋输送机叶片一起旋转的力是物料自身重量和螺旋输送机机壳对物料的摩擦阻力。螺旋输送机旋转轴上焊的螺旋叶片,叶片的面型根据输送物料的不同有实体面型、带式面型、叶片面型等型式。螺旋输送机的螺旋轴在物料运动方向的终端有止推轴承以随物料给螺旋的轴向反力,在机长较长时,应加中间吊挂轴承。
Rotating helical blade material goes by conveyor screw conveyor, so that the material and screw conveyor blades rotating force is the frictional resistance of the materials of its own weight and screw conveyor enclosure materials. The helical blade of the screw conveyor rotating shaft welding, the face of the blade according to the transportation of materials of different entities face, with a face, leaves face type. Terminal screw conveyor screw axis in the direction of movement of materials thrust bearing with the material to the axial reaction force of the spiral, the captain long, should be added intermediate hanger bearings.
