The WBH Batch-Type Single Shaft Mixer is the ideal machine to obtain highest quality mixtures in perfectly reproducible batches. In the last three decades MAP has supplied thousands of mixers to a large variety of industries worldwide. Mixing tests for customers are performed in the Group’s own laboratories in currently more than fifteen countries.
TECHNICAL SPECS
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 full material mixing shaft, two drum closing end plates that carry flanged end bearing assemblies complete with integrated air or gas-purged shaft seals, 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 vessel. 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 WBH Horizontal Single Shaft 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 ingredients with 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 low viscosity pastes.
