Abstract
A wear-resistant rotor wheel for use as an atomizer wheel for the atomization of slurries of highly abrasive materials or as a rotor wheel in an agigator or pump of the centrifugal type. The cylindrical side wall of the wheel is formed with ejection orifices and defines together with a body of revolution arranged around the wheel hub a bowl-shaped space which is downwardly limited by an annular plate of wear-resistant sintered material covering the wheel bottom. The annular plate is arranged to be spaced from the wheel bottom with its outer circumference sealingly joining the inner side of the side wall, so that solid particles from a slurry are not allowed to enter between the circumference of the plate and the side wall, while the side wall is allowed to follow deflection of the wheel bottom without subjecting the annular plate to deformation forces. The annular plate may be firmly secured either at the side wall, in which case it is connected with the body of revolution and axially displaceable together therewith relative to the hub, or at the hub, in which case a sealing ring is interposed between the annular plate and the side wall so as to allow relative movement therebetween…
