The rotation and revolution of machine is finished through a set of motor and cycloidal needle wheel reducer. Being adapted two scews to carry out stirring asymmetrically, it makes the stirring scope of raw material is wide and the mixing is uniform better and quickly. Particularly it is suitable for raw materials having large difference in specific gravity and large ratio of formulation. Applications: Make the dry or wet granule uniform. Crush the whole conglomeration. Make granule. Crush heat sensitivity raw materials.
