摘要

PROBLEM TO BE SOLVED: To provide the device capable of uniformly and effectively treating the surfaces of solid particles. ;SOLUTION: A first cylindrical treating chamber 29a and a powder supply port 30 opposite to the front surface of a first rotary rotor 2a are installed. In the central part of a first rear wall 8a of the first cylindrical treating chamber 29a opposite to the rear surface of the first rotary rotor 2a, a powder discharge port 10a is provided, and the first rotary rotor 2a and a rotary driving shaft are connected. When the height of a blade 9a, a gap between the tip and the front wall of the blade 9a, the longest diameter of the first rotary rotor 2a, and the gap between the blade 9a and a sidewalk 7a of the first cylindrical treating chamber are defined as H_a, L_1a, R_1a, and L_2a respectively, H_a, L_1a, R_1a, and L_2a is allowed to satisfy the following conditions. 0.1≤L_1a/H_a≤5.0, 50×10^-3≤H_a/R_1a≤400×10^-3, 1.0×10^-3≤L_2a/R_1a≤95×10^-3.;COPYRIGHT: (C)1998,JPO
