PROBLEM TO BE SOLVED: To mix and diffuse a molding material without bonding the same to a diffusion blade when a thermosetting resin is formed. SOLUTION: A vertical mixer is constituted by providing a diffusion blade 2 performing the mixing of a powder or particles, the mixing of the powder and a liquid or granulation to the bottom surface of a mixer main body 1 and has blades 3 having an angle in the rotary direction of the diffusion blade 2. In the cross-sectional shape of the blades 3, when the thickness of the lower edge 3a preceding in an advance direction is set to A and the gap between the bottom surface of the mixing main body 1 and the lower edge 3a of each of the blades 3 is set to D, the ratio (A/D) of A to D is 3 or less. |
