Twin Screw Conveyor Manufacturers

Twin Screw Conveyor is an important equipment for achieving stable material transfer. Different manufacturers show their uniqueness in equipment structure, material, drive configuration, etc. For example, some manufacturers may focus more on shaftless Twin Screw Conveyors for handling sticky materials, while others have expertise in manufacturing shafted Twin Screw Conveyors for large-volume, long-distance transportation. In addition, for specific material properties (such as abrasiveness, corrosiveness) or harsh operating environments, manufacturers provide customized service capabilities, including adjusting the shape of spiral blades and selecting special alloy materials.
What are the types of Twin Screw Conveyors?
Twin Screw Conveyors can be mainly divided into the following types according to the direction of material conveying:
Horizontal Twin Screw Conveyor
Structural features: The material is pushed by two side-by-side spirals in the horizontal direction. The conveying trough is usually U-shaped or tubular, with two spiral shafts installed in parallel.
Applicable scenarios: Widely used in situations where materials need to be transported from one point to another at the same height, such as connecting different processing equipment, and transferring materials over short or long distances on the production line.
Advantages: The structure is relatively simple, installation and maintenance are relatively convenient, and the operation is stable.
Tilted Twin Screw Conveyor
Structural features: The entire or part of the conveying section of the conveyor is tilted at a certain angle. In order to prevent the material from flowing back due to gravity, the design of the spiral blades (such as pitch, blade shape) may require special adjustments, or a deeper trough design.
Applicable scenarios: Commonly used to lift materials to the top of the silo, high-level feed ports (such as crushers, mixers), or connect production lines at different heights.
Advantages: Compared with vertical conveyors, the inclination angle is more flexible and more adaptable to material characteristics, but the floor space will be slightly larger than that of horizontal conveyors.
What are the advantages of Twin Screw Conveyor?
With its unique double-helix design, Twin Screw Conveyor has many advantages in specific application scenarios:
High conveying stability: The two spiral blades work together to form a relatively closed conveying channel, which can push the material more evenly and stably, reduce the fluctuation and slipping of the material during the conveying process, and is particularly suitable for occasions with high requirements for conveying stability.
Strong processing capacity: Compared with the single screw conveyor of the same diameter, the double-helix design provides a larger material cross-sectional area and stronger propulsion force, so in theory and in actual operation, it can usually achieve a higher material conveying volume.
Wide material adaptability: Especially when dealing with some materials with poor fluidity, strong viscosity, easy arching or bridging, the interaction of the double helix can effectively break the arch, loosen the material, avoid blockage, and achieve smoother conveying.
Mixing and stirring effect: During the rotation of the two spiral blades, the material will have a certain shearing, flipping and mixing effect. This allows the Twin Screw Conveyor to play a preliminary mixing or stirring role while conveying the material, which is particularly beneficial for process links that require material uniformity or premixing.
What are the applications of Twin Screw Conveyor?
Twin Screw Conveyor performs well in a variety of material conveying scenarios and has a wide range of applications, mainly in the following aspects:
Horizontal or inclined conveying of materials: Twin Screw Conveyor can stably transfer various bulk, granular, powdered or small block materials from one position to another in the horizontal direction. When it is necessary to overcome the height difference, it can also complete the lifting and conveying of materials at a certain tilt angle.
Handling special materials: This type of equipment is particularly good at conveying materials that are difficult to handle with single screw conveyors. For example, for materials with strong viscosity, easy to agglomerate, and easy to entangle, the double screw design can effectively break the arch, loosen the material, and prevent blockage.
Achieve mixing or stirring of materials: During the conveying process, the coordinated rotation of the two screws can produce a certain amount of flipping, shearing and mixing effects on the material. This makes Twin Screw Conveyor not only a conveying tool, but also takes into account the initial mixing or homogenization of materials.
Conveying materials in a closed environment: Many Twin Screw Conveyors use a U-shaped groove with a cover or a completely closed tubular structure, which effectively isolates the material from the external environment during the conveying process, preventing dust from spilling out, the material from getting wet or contaminated.
The key to selecting a Twin Screw Conveyor manufacturer is whether it can provide equipment that meets actual operating needs. The material characteristics, actual daily or hourly processing volume, required conveying path, on-site space restrictions, and requirements for equipment materials and operating environment should be fully considered. Manufacturers with customization capabilities can adjust the design of the spiral blades, select a suitable drive system, or provide specific anti-wear/anti-corrosion treatments based on this information to ensure stable operation of the equipment.
