1. Strong anti winding performance: Due to the absence of intermediate bearings, it has special advantages in conveying belt shaped, viscous, and easily entangled materials, which can avoid material blockage.

2. Large conveying capacity: The torque of the shaftless screw conveyor can reach 4000N/m, and the conveying capacity is 1.5 times that of a shaft.

3. Long conveying distance: The conveying length of a single machine can reach 60 meters, and multi-level series installation can be adopted according to user needs.

4. Good sealing performance: The groove cover with appropriate gaskets can achieve odorless operation and form a barrier to prevent any atmospheric medium from entering the system. It can ensure environmental hygiene and ensure that the delivered materials are not contaminated, have no odor leakage, and ensure the hygiene of the conveying environment.

5. Mobile operation: It can add materials at single or multiple points, achieving the effect of both bottom discharge and end discharge.

6. Long service life: using specially made plastic sheets, rubber sheets, or cast stone sheets to avoid direct friction between the blades and the shell, with good wear resistance.

The shaftless screw conveyor adopts a design without a central axis, which makes material transportation smoother and effectively prevents the influence of blockages and entanglements. It is very suitable for materials that are easy to entangle, such as sticky, high moisture content, and ribbon. Axirless screw conveyors are generally arranged horizontally or can be placed at an angle of inclination, but the inclination angle will not exceed 45 °.

The shaftless screw conveyor is driven by an electric motor to operate a cycloidal reducer. It is driven by a mechanical seal shaft and a connecting plate on the shaftless screw body to rotate and work. When the sludge is discharged to the feeding port on the upper part of the U-shaped groove, it is discharged through the discharge port on the lower part of the U-shaped groove through the screw drive.

The conveying capacity of axial screw conveyors at different angles

The values in the table above for the axial screw conveyor are the conveying capacity for conveying semi liquid materials. When conveying materials with certain stacking characteristics such as granular, loose, and sludge, the values in the table should be increased by 10% -20%.

The values in the table represent the conveying capacity at a speed of n=30r/min. When using wear-resistant lining plates, the speed can increase by 20% -100% depending on the diameter, and the corresponding conveying capacity also increases by 20% -100%.
