Atomizer wheel with wear-resistant insert therefor

摘要

The atomizer wheel comprises a plurality of ejection apertures distributed over the circumference of an external wall (103), in which a plurality of inserts are arranged. The inserts each comprises a bushing (108) and a wear-resistant lining (107) arranged in said bushing (108) such that a contact surface (120) of said lining (107) abuts against an internal side of said bushing (108). Each insert is provided with a transition surface (121) extending between an inner end face (124) of the lining (107) and the contact surface (120), and the transition surface (121) comprises at least one portion (126) forming an angle with said contact surface (120), by which it is possible to direct the flow of the material to be atomized along the transition surface (121) of the lining (107) and further down to the inner side of the external wall and thus avoid wear on the bushing (108).
