Abstract The invention relates to a process for coating solid particles in powder form with a material which is solid or of high viscosity at room temperature. A device which can be used for carrying out the process comprises a housing (1) with a conical surface (16) and a rotor (7) mounted in the housing and provided with a conical surface (9). The housing has an inlet (20) through which a melt of the solid material can be supplied to a gap between the conical surfaces of the housing and the rotor and an inlet (12) for supplying powder material to the top surface (8a) of the rotor. As the rotor rotates, a film is formed on the conical surface of the housing and at the same time powder is slung, with the aid of vanes (10) on the rotor against the film. The material is worked and pressed out through an outlet (30) by wings (11) on the rotor.
