Double axis screw conveyor

The principle of a double axis screw conveyor is to install a physical screw in two seamless steel pipes, one is left-handed and the other is right-handed. During operation, two spirals rotate by meshing with a pair of gears located at the shaft extension position. Due to the rotation of the spiral body, the material moves axially to achieve the conveying purpose.

Structural characteristics:

1. The spiral shaft is connected to the suspension bearing, head and tail shaft, and does not require axial movement for installation and disassembly, making maintenance convenient. The core shaft is long, with less lifting and fewer fault points.

2. Adopting a diameter changing structure, increasing the volume of the suspension bearing, and avoiding contact between the suspension bearing and the material, the service life of the suspension bearing can reach more than two years.

3. All transmission components adopt a floating connection method, and the suspension bearings are of a general structure, so that the spiral body, suspension bearings, and tail always form a unified rotating floating body, and the conveying resistance rotates freely within a certain range to avoid material blockage or blockage.

4. The head and tail bearing seats are located outside the housing, and all bearings use multi-layer sealing boxes and sealing technology, with a long service life.

5. Compared with other conveying equipment, it has the advantages of small cross-sectional size, good sealing performance, smooth operation, safe intermediate loading and unloading, and simple maintenance.
