Description
The closed pipe-type screw conveyor is a pipe with a shaft inside with welded screw blades and passive bearing. The screw's blades have different pitch which depends on the type of the transported raw material and the planned capacity. This type of conveyor is closed, which means that the screw cannot be accessed directly. Due to the closed structure, the transported raw material does not spill outside the machine during transport.
The machine can be equipped with a pull screw. In this version, the drive unit is located in the direction of the raw material feeding. Some screw conveyors are equipped with push screws with gear motor installed on the feeding side. The screw conveyor is fitted with an initial or end bearing. Depending on the type of transported raw material, slide or bearing rests are installed.
Horizontal screw conveyor has the advantages of sealed operation, simple structure. screw conveyor suitable for conveying powdery, granular and small bulk materials horizontally or aslope, such as coal, ash, slag, cement, food, etc. screw conveyor is an new transportation equipment.
Spare parts of cement screw conveyor include screw blade, reducer, intermediate bearing (hanging type), Tailstock, flange plate, cardan joint etc.
Performance and Features
(1),It can be used to control the flow of material in processing operations which depend upon accurate batching
(2),It can be utilized in the horizontal, vertical or any inclined position depending upon the characteristics of the product being conveyed.
(3),It can be used as a mixer or agitator to blend dry or fluid ingredients, provide crystallization or coagulant action, or maintain solutions in suspension.
(4),Screw conveyors can have multiple conveyor outlets, making discharge to multiple outlets cost effective.
(5),It can be jacketed to serve as a drier or cooler by running hot or cold water through the jacket.
(6),It can be made out of a variety of materials to resist corrosion, abrasion or heat, depending upon the product being conveyed.
(7),It can be outfitted with multiple inlet and discharge points.
Application Scope
Universal joint is generally used for angle adjustment on conveyors, specially cement screw conveyor.
