Wet mixer

The continuous ploughshare mixer uses the mixing and fluid process introduced to mixing technology by Lödige. The ploughshare shovels in special arrangement on a mixing shaft in a horizontal, cylindrical drum rotate. Their peripheral speed and geometric form are coordinated in such a way that the mix is moved out of the product bed against the centrifugal force and in axial direction at the same time. The mixing elements having a defined shape and a special arrangement on the shaft, they ensure not only a reliable product conveyance but also a sufficient back-mixing of the product. All the product is constantly involved in the process, ensures a maximum mixing intensity at even the highest throughputs and shortest residence times until the product is discharged out of the mixer via an outlet. The continuous process can be run at filling levels between 20 % and 50 % without influencing the mixing quality. Choppers can be additionally installed in the mixing drum.

The CoriMix® is a high-speed, continuous mixer for high throughputs, especially developed for homogeneous mixing of liquid and pasty components into dry substances. The system is based on the high peripheral speed of the mixing shaft tools of up to 50 m/s. The product is moved through the mixing chamber in a plug-flow manner. The retention time 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. Liquid components 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. The liquid distribution is similar to a nozzle but avoiding any risk of clogging or disturbance of the spray.

The ploughshare mixer for batch operation uses the mixing and fluid process introduced to mixing technology by Lödige. The ploughshare shovels on the mixing shaft in a horizontal, cylindrical drum rotate to the wall. Their peripheral speed and geometric form are coordinated in such a way that the mix is moved out of the product bed against the centrifugal force and in axial direction at the same time. All the product is constantly involved in the process, ensures a maximum mixing intensity at even the highest throughputs and shortest residence times until the product is discharged out of the mixer via an outlet. Thanks to their form adapted to individual application and the speed adjustment, Lödige ploughshare mixers can be used for a wide range of applications. Choppers can be additionally installed in the mixing drum to increase the turbulence in the mixing process. This ensures the mixing of fine particles in small quantity and enables the dispersion of these products .

The laboratory model supplements the well-established Lödige mixing granulator range. The laboratory mixing granulator permits the same process steps as the production machines: — Mixing — Moistening — Granulation — Temperature control (using double jacket) The laboratory mixing granulator is delivered operation-ready with a CE conformity declaration. For the sizes, please refer to the machine flyer. A three-bladed impeller rotates at the bottom of the vertical, cylindrical mixing vessel, to create a vortex type of circulation for the material to be mixed. Very short mixing times and excellent mixing quality are achieved, even if the product components are extremely different. The separately driven chopper (only for the 5, 10 and 15 l vessel) is designed for breaking up of agglomerated material, for uniform moistening, wet granulation and streak-free mixing of dyes, as required.
