Intensive mixer

A batch type device for mixing, cooling, heating, drying and/or granulating powdery, granular and/or pasty materials, comprising:

• a conical mixing vessel having a sidewall with a smooth inner wall surface and a vertical axis, said vessel narrowing in a downward direction;
• a mixing shaft rotatably mounted for rotation in said vessel along said vertical axis;
• a plurality of elements pivotally mounted to and projecting in a generally radial direction from said shaft to adjacent said vessel inner wall surface;
• a plurality of chopping knives fixedly mounted to said shaft, above said pivotally mounted elements and projecting in a generally radial direction from said shaft to adjacent said vessel inner wall surface;
• and
• a drive motor for rotatably driving said mixing shaft.

• a mixing shaft rotatably mounted for rotation in said vessel along said vertical axis;
• a plurality of elements projecting in a generally radial direction from said shaft to adjacent said vessel inner wall surface;
• one or more mixing paddles pivotally mounted at a distal end of each projecting element, each paddle coupled to a single element;
• a chopper in the top of said vessel for chopping material in an upper portion of the vessel above said mixing paddles;
• and
• a drive motor for rotatably driving said mixing shaft.

A device for mixing, cooling, heating, drying and/or granulating powdery, granular and/or pasty materials, comprising:

• a conical mixing vessel having a sidewall with a smooth, inner wall surface and a vertical axis, said vessel narrowing continuously from a top of the vessel to a base of the vessel in a downward direction;
• a mixing shaft rotatably mounted for rotation in said vessel along said vertical axis;
• a plurality of elements projecting in a generally radial direction from said shaft adjacent said vessel inner wall surface;
• one or more mixing paddles pivotally mounted at a distal end of each projecting element;
• a chopper in the top of said vessel for chopping material in an upper portion of the vessel, above said mixing paddles;
• and
• a drive motor for rotatably driving said mixing shaft.
