The ploughshare mixer for batch operation uses the mixing and fluid process introduced to mixing technology by Lödige . High-quality mixes are achieved through equipment with tools which are adapted perfectly to the respective task.
The ploughshare shovels in special arrangement on a mixing shaft in a horizontal, cylindrical drum rotate closely 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. In addition, the shape of the shovels lifts the product particles from the drum wall. 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. The so-called ??mechanical?? fluid bed generated in this way, whereby 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 ?? for processing bulk solids (powdery, grainy, fibrous) or pumpable products.
Products of different bulk density and structure can be easily mixed.
Choppers can be additionally installed in the mixing drum to increase the turbulence in the mixing process. This also ensures the mixing of fine particles in small quantity and enables the dispersion of product agglomerations and primary particles.
The fluid bed generated mechanically achieves intensive separation of particles, especially in the upper area of the mixing drum. This optimizes the surface contact of the particles with liquids permitting lump-free mixing and homogeneous distribution.
