The CoriMix continuous-ring layer mixer (photo) a features a ring layer system that rotates with circumferential speeds of up to 40 m/s. As a result, the product components are accelerated through centrifugal force. This causes a ring layer to be formed. Within this concentric layer there are enormous differences in speed between the rapidly rotating mixing tools and the stationary container wall. As a consequence, friction is particularly high in the ring layer profile. The specially shaped tools of the mixing unit move the product during the subsequent process in a pattern similar to plug flow through the mixing chamber. Because this happens very rapidly, the residence times are very short and the residence time deviation is narrow. Depending on the product, throughput of up to 0.50 m3/h in a laboratory setting and up to 500 m3/h in production can be achieved, with an effective volume of between 5 and 3,000 L. — Gebr.
