Application

The fluid bed batch-mixer is the ideal machine to obtain highest quality mixtures in perfectly reproducible batches. It is suitable for mixing of solid materials in powder and granular form, with the addition of liquids in minor quantities.
The particular shape, the position and the speed of rotation of the mixing tools create a centrifugal swirling movement that enables materials to be projected in three-dimensional manner and to mix. This ensures that components with different particle size and density are perfectly blended with high precision within the shortest possible time.
The formation of dead spots or slow-movement zones in the mixing drum is prevented ensuring precise mixing.

Design

The fluid bed batch-mixer 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 purged shaft seals, and a drive unit complete with power transmission.
Various sizes and design features allow custom designed solutions for specific material characteristics.
High-speed choppers can be installed for the addition of liquids and eliminate lumps.
Large cleanout doors guarantee quick cleaning and inspection.
