ABSTRACT:
An apparatus for treating the surfaces of solid particles has at least a first cylindrical treating chamber and a rotary shaft and a first rotor having two or more blades on its front face, contained in the first cylindrical treating chamber. A powder charging aperture for introducing the solid particles into the first cylindrical treating chamber together with gas is provided at the center of the front wall of the first cylindrical treating chamber, opposed to the front face of the first rotor. A first powder discharging aperture for discharging the treated solid particles is provided at the center of the rear wall of the first cylindrical treating chamber, opposed to the rear face of the first rotor. The first rotor is connected with the rotary shaft and rotated by the rotation of the rotary shaft. The height H.sub.a of the blades, the gap L.sub.1a between the tip of each of the blades and the front wall, the largest diameter R.sub.1a of the first rotor and the gap L.sub.2a between the blades and the sidewall of the first cylindrical treating chamber satisfy the following conditions:
