<p>This invention relates to a device for particle blasting, comprising a mixing device for mixing the particles and the carrier gas. The mixing device comprises, on the one hand, a mixing plate (3) wherein at least one supply channel (6) for the carrier gas, at least one supply channel for the particles (14) and at least one discharge channel (7) for the mixture are provided, and on the other hand, comprises a rotatable distribution disc (1) provided with cavities (2), which during rotation are positioned in such a way that they are first filled with particles and then form a temporary connection between the supply channel (6) and the discharge channel (7), with the result that the carrier gas and the particles are mixed. Since both the supply channel and the discharge channel are provided in one and the same element, the seal between mixing plate and rotor is easy to achieve.</p> |
