Abstract

An atomizer wheel comprising a central hub for securing the wheel on a rotatable shaft in a centrifugal atomizer associated with an atomizer drying system, a ring-shaped acceleration chamber arranged around the hub and having an upper ring opening through which the liquid to be atomized may be added to the acceleration chamber, at least one throw-out face for passing the liquid outwardly in the atomizer wheel in a direction toward its periphery, and a plurality of throw-out channels which, distributed with a mutual angular distance along the periphery of the acceleration chamber, extend transversely out through the outer wall of the chamber and serve to throw the liquid out of the acceleration chamber during the rotation of the atomizer wheel. At least one throw-out face is provided on a separate wear ring which is provided on the atomizer wheel and comprises a hard and wear resistant material. The wear ring is also divided into a plurality of wear elements by cuts that extend from the periphery of the ring substantially in a direction directed to a substantially circular area around the axis of rotation, the cuts extending obliquely forwardly in the direction of rotation from at least one throw-out face of the ring.
