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.
Performance and Features
It can be used to control the flow of material in processing operations which depend upon accurate batching
It can be utilized in the horizontal, vertical or any inclined position depending upon the characteristics of the product being conveyed.
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.
Screw conveyors can have multiple conveyor outlets, making discharge to multiple outlets cost effective.
It can be jacketed to serve as a drier or cooler by running hot or cold water through the jacket.
It can be made out of a variety of materials to resist corrosion, abrasion or heat, depending upon the product being conveyed.
It can be outfitted with multiple inlet and discharge points.
It is continuous transmission equipment extensively used in the field of the metallurgy, construction materials, chemical industry, food and the machinery processing.
The screw conveyor consists of power device, gear box, coupling, screw axis and hanging bearing. The screw axis is made of several sections which connected with spline. Hence, the conveyor hold large load capacity and convenient to dismounting. It is open a besel on the casing to ensure a safe operation.
The material moves along the spiral within the tube. The unique action of the flexible spiral conveyor eliminates the risk of the product separation that can take place in conventional pneumatic conveying systems where mixed materials have components of different densities and particle size.
Components of Screw Conveyor
Choosing Model Noticed
1. What is the conveying material and its physical characteristics? such as bulk density, feeding size, temperature, mositure content etc. 2. What is the processing capacity of the conveyor? 3. What is the inclination angle of the conveyor? 4. What is the conveying length (distance between inlet and outlet)?
