Ring layer mixer RINGMIX

RINGMIX-The ring layer mixer agitator system delivers high peripheral speeds of up to 50 m/s. The centrifugal force pushes the product outwards into a ring layer on the vessel side wall. The high speed rotating agitator, combined with the use of different mixing elements, guarantees a high and agglomerate-free mixing intensity. Fluids are injected tangentially into the product through special nozzles and mixing, coating on the material. This is effective for material mixing, coating or dying. The system is based on the high peripheral speed of the mixing shaft tools of up to 50 m/s. The resulting centrifugal force forms a concentric ring layer of product along the drum wall. The product is moved through the mixing chamber in a plug-flow manner. The retention time depends on the filling level, speed, geometry and mixing tool adjustment as well as the throughputs but is extremely short compared with a continuous Ploughshare Mixer. The mixing chamber is divided into zones with different mixing tools enabling different shear intensity by selecting and adjusting the mixing tools according to each application. The friction of the product is increased through the high speed of the mixing tools but is still gentle enough due to the short residence time during the process. Liquid components (additives, coating agent) are introduced directly into the product ring layer – either via tangentially placed liquid pipes through the drum wall or via a hollow mixing shaft with specially perforated tools. However, moistening of the mixer wall and shaft is largely prevented.
