The invention relates to a device (2) for producing granules (4) from a mineral melt (6), comprising a melt feeding device (8) and a rotary atomizer (10) having a rotatably disposed rotational body (12), the atomizing of the melt (6) into microparticles taking place on the surface (4) thereof. The microparticles thus obtained take a trajectory (20) leading away from the rotational body (12). The invention is characterized in that the rotational body (12) comprises a metallic support body (16) having a ceramic coating (18) applied thereon.
