Screw Conveyors:
Screw conveyors, also known as auger conveyors or industrial screw conveyors, are systems designed to transfer free-flowing and non-free-flowing, dry and semi-dry bulk materials. Note: Since the operation of the system involves a screw cutting through the bulk materials, we do not recommend using screw conveyors to process substances that are sticky or do not break down easily, such as gels.
Applications;
Screw conveyors assist in moving, or conveying items such as: packages, equipment, food, or products from one area to another, usually for the purpose of performing automated or semi-automated finishing or manufacturing processes. These conveyors are able to transport dry, loose materials between places such as pits, trucks, barrels, rail cars, silos, hoppers, and vats.
To that end, screw conveyors can be found in a wide range of industries and applications, such as: construction, oil and gas, mining, chemical, pharmaceutical, plastic, food processing and agricultural.
In farming and agriculture, screw conveyors are used as a part of machinery, like balers or threshers, that assist in conveying grains and animal feed to various locations. In food processing, screw conveyors transport dry ingredients—such as nuts, salt, and flour—that are used in making food products. The construction industry uses industrial screw conveyors to mix wet and dry ingredients to produce plaster or cement.
Features:
1. Efficient conveying: LS tubular screw conveyor adopts a new suspended intermediate suspension bearing frame, which enlarges the space of material conveying and reduces the logistics resistance. With the design of small diameter, high speed and variable pitch, it ensures smooth, fast and uniform feeding.
2. Arrangement at will: The shell of tubular screw conveyor is made of high quality seamless steel tube, and each section is connected as a whole through flange. It can be transported continuously at both horizontal and large inclination angles. It can be directly connected and fixed with supporting equipment, without foundation, make full use of space, and it is very convenient to move and disassemble.
3. Diversified connection: Flange connection, cloth connection, cloth suspender connection and universal interface connection can be used for inlet and outlet ports.
4. Reliable Sealing: Water-proof device is installed at the joint of the shell pipe, and the process hole has been carefully improved to avoid blocking and stuffing accidents caused by cement caking in the pipe caused by rainwater infiltration.
5. No need to add oil: Because of the use of novel intermediate bearing materials, it can reduce friction, wear resistance and self-lubrication, even if long-term use, it is not necessary to add lubricating grease, which can avoid the side effects of oil and cement mixing on bushes and shafts.
6. Special reducer: The special reducer made by our company is advanced and reasonable in design. It has the advantages of small size, light weight, large torque, fast speed, no oil leakage, no noise, etc. It also has a stop-back structure, which is suitable for thrust transmission with large inclination angle.
