Laboratory/Pilot Multi-Shaft Mixer

Laboratory/Pilot Multi-Shaft Mixer

Effective process for the production of adhesives, sealants and other paste products from the low to high viscosity range.


A low-speed wall and bottom scraper feeds the other mixing devices continuously with the mixed product in a tangential direction and serves simultaneously in a stationary vessel as a discharge support. A separate screw ensures the vertical, large-volume mixing flow and a separate, high speed mixing shaft with one or more dissolver disks grants for the necessary dispersion power.

The laboratory and pilot plant multi-shaft-mixers are particularly suited for analyzing and optimizing the mixing process. The derived process knowledge can be used to scale up the machine to the desired production size.
