ABSTRACT:
A rotary tank supported by a bearing stand on a horizontal shaft in a freely rotatable manner to form a grinding/mixing chamber having an inner wall of modified cross-section such as oval one at the horizontal center axis position is driven by a rotary drive motor for driving said rotary tank to rotate it adjustably at any relatively low speed in a certain direction. A grinding/mixing blade is inserted into said grinding/mixing chamber over its whole length and mounted at the coaxial position on the rotary shaft other than that for the rotary tank. The grinding/mixing blade has a cross-section in which its long diameter portion is shorter than the short diameter portion of said grinding/mixing chamber, and is driven by a rotary drive motor for driving said grinding/mixing blade to rotate it adjustably at any speed in normal or reverse direction to grind and mix the bulk materials charged into said grinding/mixing chamber by relative rotating motions of rotary tank and grinding/mixing blade and also to perform coating, granulation and dispersion by these actions.
