(1) have a physical spiral blade screw conveyor spiral face with spiral face and leaves spiral face Three. Entity s preparation method called helical surface, its helical pitch type GX 0.8 times the diameter of the blade,Bolted Type Cement Silo spiral loses Send for conveying powdery and granular materials. Belt, also known as D helical surface preparation method, with its spiral screw blade pitch The same diameter, suitable for conveying powder and small pieces of material. Vane helical surface is seldom used, mainly for transport Viscosity and compressibility of the material, the conveying process, and complete mixing, mixing step in which the screw Pitch of approximately 1.2 times the diameter of the spiral blade.
(2) screw conveyor helical blade has two kinds of L and Drotation.
(3) the type of screw conveyor with horizontal fixed screw conveyor, vertical screw conveyor. Asphalt Mixing Plant conveyor is of a type most commonly used. Vertical screw conveyor for materials to enhance short distance, Conveyor height is generally not more than 8m, spiral blade surface for the entity type, it must have horizontal screw feeder in order to maintain Permit the necessary feed pressure.
(4) LS, GX-type screw conveyor material outlet end, should be set to 1/2 to 1 turn reverse helical segments, to prevent powder Clogging material ends.
(5) by a screw conveyor screw conveyor body material inlet and outlet and the drive unit consists of three parts.Screw machine body by the head bearings, rear bearings, suspension bearings, spiral, shell, cover and base, etc.Components.
Drive unit consists of motor, reducer, coupling and base formed.
