  • Page 32: Operating Principle

    3.3 Operating principle The Batch-Type Ploughshare Mixers WBHX is based on the principle of mechanical fluidisation of the material. The particular shape, position and rotation speed of the mixing tools, creates a vortex motion, which allows the materials to be projected in a three-dimensional way and to merge with each other. This ensures that compo- nents with a different particle size and bulk density are perfectly blended and mixed with high precision within the shortest possible time.
