Abstract
Device for treating particles, which device comprises a vortex chamber defined by end walls at both ends ans a circular wall, a rotation imparting device comprising fluid feeding means arranged in a mainly tangential direction, a particle outlet and a central fluid outlet, which device further comprises an auxiliary chamber coaxially arranged with the vortex chamber defining a treating zone, which auxiliary chamber has a circular outer wall and an end wall and opens into the vortex chamber through an opening in the end wall of the vortex chamber opposite the central fluid outlet, a device for injecting particles coaxially into the treating zone, and a device for feeding a treating fluid into the treating zone in mainly axial direction, wherein the ratio of the area of the opening to the cross- sectional area of the vortex chamber is less than 0.50.
