WBH Horizontal Single Shaft Batch Mixers consist of a mixing drum vessel with an inlet, an outlet with discharge valve and a venting spout, a mixing shaft, two drum closing end plates that carry flanged end bearing assemblies complete with integrated adjustable shaft sealing unit, and a drive unit complete with power transmission.
Ploughshare or inclined blade-type shovel tools rotate as mixing tools in a special arrangement on the mixer shaft in a horizontal, cylindrical drum. The result is a turbulence in the mix that constantly involves all the product particles in the mixing process. The formation of dead spots or slow-movement zones in the mixing drum is prevented ensuring precise mixing. In some cases, to obtain the desired mixing effect, separately driven high-speed choppers can be installed.

Function |
|
|
|
|
|
The Horizontal Single Shaft WBH Batch Mixer is based on the principle of mechanical fluidisation of the product.
The particular shape, position and rotation speed of the mixing tools, creates a centrifugal vortex motion, which allows the materials to be projected in a three-dimensional way and to merge with each other. This ensures that components with a different particle size and bulk density are perfectly blended and mixed with high precision within the shortest possible time.
WBH Batch-type Mixers are used for mixing dry powders, granules or short fibres, for moistening, agglomerating or granulating the same materials, or for mixing liquids or pastes with low viscosity.
