for Powders & Bulk Solids



The Vitomix ribbon screw mixer is a mid-shear batch mixer, capable of ultra-short cycle times with up to 8 times more transport volume than conventional ribbon screw mixers. In addition, the Vitomix has a wider range of operation with top speeds of 0.4 m/s to 6.0 m/s.

The multifunctional Vitomix ribbon screw mixer combines gentle mixing and mid to low shear in one compact machine. It is ideal for adding liquids and creates a homogeneous mixture without the use of lump breakers. The ribbon screw mixer is an energy-efficient mixer that reduces energy costs and saves on mixing time.


The Vitomix ribbon screw mixer is equipped with two symmetrical ribbon screws mounted on an orbital arm that transports the product from the bottom of the vessel to the surface. The material flows downwards through the centre of the vessel by gravity whilst the high rotational speed of the agitator ensures mid-shear mixing in very short batch times.

A distinctive factor about the Vitomix is the double ribbon screw which enables a transport capacity of up to eight times that of standard conical screw mixers. The result is a substantial improvement in mixing efficiency and a much more efficient and faster mixing process even at lower speeds.

The design of the two conical screws creates a fluidized bed in the upper part of the mixer cone that is perfect for adding liquids. A liquid spraying system can be fitted through the hollow axle, providing flexibility in the location and the number of nozzles and lances you choose; without influencing mixing properties or spraying on metal parts.
