The continuous ploughshare mixer KM developed by Lödige is suitable for processing powdery, fibrous or granular solids as well as liquids and pastes with low viscosity. Granulation processes can also be carried out with the continuous mixer at minimum dwell time. The continuous mixer is based on the process of the mechanically generated turbulent fluidised bed.
During this process, ploughshare shovels rotate close to the wall in a horizontal, cylindrical drum. Their peripheral speed and geometric shape is rated such that they take the mixing components off of the drum wall and toss them into the free mixing compartment from the product bed. Therefore, due to the continuous mixing of the entire product, intensive mixing is achieved even at extensive throughputs of material to be mixed. The product transport is ensured by the special shape and arrangement of the mixing elements. In this manner, a high homogeneity and consistent reproducibility of the final product is achieved during short mixing or dwell times of only 25 to 60 s. The smallest model with a drum capacity of 5 l, has a throughput capacity of 0.25 m³/h, depending on the dwell time and filling level. The throughput capacity of the larg-est model with a drum volume of 30,000 l is approx. 900 m³/h.
