The rotating cylinder of EYH two-dimensional mixer can achieve two motions at the same time. One is the rotation of the cylinder and the other is swinging of the cylinder along the swinging rack. Materials to be mixed will be mixed from left to right and vice versa when the cylinder is swinging. As a result of these two motions, materials can be mixed fully in a short time. EYH two-dimensional mixer is suitable for mixing of all powder and granule materials.
