Classification and structural characteristics

(A) 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 for conveying powdery and granular materials. Belt, also known as D helical surface preparation method, and its helical pitch of the helical blade of the same diameter, suitable for conveying powder and small pieces of material. Vane helicoid seldom, mainly used for conveying material viscosity and compressibility, in the transportation process, and complete mixing, mixing step in which the helical pitch of approximately 1.2 times the diameter of the spiral blade.
(2) screw conveyor helical blade has two kinds of L and D rotation.
(3) the type of screw conveyor with horizontal fixed screw conveyor, concrete batching plant. Stationary horizontal conveyor is of a type most commonly used. Vertical screw conveyor for short-range upgrade materials, transport height is generally not more than 8m, spiral blade surface for the entity type, it must have horizontal screw feeder in order to ensure 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 clogging powder 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 composition.
Drive unit consists of motor, reducer, coupling and base consisting.
