Round Tube Screw Conveyor

Product introduction of Round Tube Screw Conveyor

The Round Tube Screw Conveyor uses the rotating screw to transport the conveyed material to the designated direction and position in a closed circular tube. It can be arranged horizontally, inclined and vertically, and can provide various solutions for the conveying of powdery or granular materials. , Widely used in flour processing, animal feed processing and other industries.

The diameter of the Round Tube Screw Conveyor is 100-1250mm, and the speed can continue to be selected (60-140 rpm), ensuring smooth, fast, uniform feeding, no material jams, large conveying capacity, and a conveying distance of 2 meters to 70 meters. Steel, stainless steel, and plastic are available in three materials. Since the conveying process is carried out in a closed pipeline, there is basically no dust pollution, and the conveyed materials will not leak to avoid polluting the workplace.

Carbon steel painted material Round Tube Screw Conveyor

It is made of carbon steel, with small diameter and high speed. Usually, the outer wall of the machine is painted, which slows down the wear and tear of the machine to a certain extent, prolongs the service life, and reduces the possibility of getting wet and rusting.

It is a conveying equipment widely used in chemical industry, building materials, grain and oil, feed, metallurgy, mining, plastics and other industries.

Stainless Steel Round Tube Screw Conveyor

Made of (304/316L stainless steel), corrosion-resistant, high-temperature resistant, easy to clean, not easy to rust, and will not pollute the conveyed materials. The inside and outside of the machine are polished more smoothly, the materials are not easy to adhere, and there is no residue in the machine.

The Stainless Steel Round Tube Screw Conveyor is suitable for applications where any contamination of the material being handled must be strictly avoided and where absolute cleanliness and perfect corrosion resistance are required, common applications include food, chemicals, pharmaceuticals and any other that requires it for hygiene, corrosion or extreme temperature application.

Plastic Round Tube Screw Conveyor

Made of polypropylene material, it has strong corrosion resistance, which solves the ineffectiveness of stainless steel and ordinary steel, and is widely used in the transportation of strong acid and highly corrosive materials.

It is specially used in the breeding industry, mainly used in chicken farms, duck farms, pig farms, cattle farms and other occasions to transport animal manure. Faster and easier without human intervention.

Advantages of Round Tube Screw Conveyor

Round Tube Screw Conveyor is a relatively common conveyor. The entire transportation process is carried out in a closed round tube, which conveys evenly, is not easy to jam, and does not generate dust.

Advantages of Round Tube Screw Conveyor

Ideal for conveying dry or semi-fluid bulk materials in completely enclosed spaces, thereby reducing the threat of hazardous contamination, dust, spillage and subsequent waste, can be conveyed from 0 to 90 degrees for flexible movement and transportation, thanks to high-quality stainless steel And steel sealing technology, they are easy to install inside and require little maintenance and cleaning.

Disadvantages of Round Tube Screw Conveyor

The conveying distance is limited to 30m, which may limit the efficiency of larger-scale manufacturing processes. Not every type of material can be transported with this type of screw conveyor and it is best to avoid transporting material with particles that stick together or have high moisture content or accumulate in the belt, as this will cause the conveyor to clog.

Specially designed Round Tube Screw Conveyor

Round tube screw conveyor is a common type of screw conveyor, but there are also some special types depending on the specific application needs. The following are some common special types of tubular screw conveyors:

1. Horizontal round tube screw conveyor: used for continuous and even transportation of loose materials horizontally or slightly inclined (below 20º). The transportation distance is generally not more than 20 meters.

2. Inclined round tube screw conveyor: used to transport materials from a lower position to a higher position. It usually has an inclined conveying section to enable the material to move smoothly to the required height. Inclined screw conveyors are widely used in applications such as lifting and lowering materials, loading them into containers or storage equipment.

3. Vertical round tube screw conveyor: Conveys materials vertically upward at 90°. The rotation speed is higher than that of ordinary screw conveyors. The lifting height is generally not more than 3 meters.

4. Cooling round tube screw conveyor: used to quickly cool high-temperature materials to the required temperature. It usually has specially designed conveying pipes and spirals to effectively cool materials through heat transfer and air cooling. It is widely used in industries such as food processing, chemical industry, and metallurgy.
