Abstract

A high-speed rotary atomiser for applying powder coating includes a housing together with a rotatable bell disc arranged at the front of housing A guidance air arrangement in the form of a rotationally symmetrical air guidance body coaxial to bell disc is provided for shaping the powder cloud generated by the high-speed rotary atomizer, which air guidance body is mounted on the front of housing. Air guidance body has a jacket surface to which guidance air be so supplied that it flows forwards along jacket surface as a substantially rotationally symmetrical air curtain along jacket surface. The air curtain flowing over the jacket surface of air guidance body impinges on the powder cloud generated by bell disc and shapes it according to the quantity and velocity of the air curtain and according to the geometry of air guidance body.
