2. The machine head is equipped with a thrust bearing, which can withstand the axial force generated in the process of material conveying, and the working life is not less than 100,000 hours.

3. Shell: The shell is U-shaped or O-shaped, with a rain cover on the top, and the material is stainless steel or carbon steel.

4. Shaftless spiral body: the material is stainless steel or carbon steel, the thickness of the blade is not less than 20mm, and the height of the spiral blade is not less than 80mm.

5. Lining plate of shaftless screw conveyor: wear-resistant plastic plate or rubber plate or cast stone plate, etc., the service life is guaranteed for more than 2 years.

The conveyed materials include: #clay #powder #flour #starch #plastic granules #cement #feed #coal #garbage treatment #sewage treatment #concrete mixing station and more than 200 kinds of materials are conveyed.

6. Inlet and outlet: There are two kinds of inlet and outlet: square and round. Generally, the form of the inlet and outlet is determined by the user.
