Spare parts

Developed by our engineering department, following Dujua standard manufacturing and quality criteria. A wide variety of material types and manufacturing processes can be applied in order to ensure a longer service life and high productivity even in the harshest environments. Examples: 

• Fins made of Hardox® wear-resistant material, which is the best abrasion-resistant steel, with uniform hardness from the surface to the core of the sheet. 
• High-hardness welded lining at the edge of the fins, conveyor side and tube region where it comes into contact with the material to be transported. 
• Shafts developed in special alloys according to the needs of each project.

Our spirals undergo strict quality control in the manufacturing process, the shafts are inserted under hydraulic pressure, and after the welding process, all spirals undergo a concentricity realignment process. This process is necessary to ensure full alignment of the mechanical assembly of components in which each spiral model is mounted.
