Both horizontal and vertically operating mixers are used for the homogenisation of various metal powders (iron, molybdenum, tantalum, niobium, chrome, aluminum, bronze, copper, tin). 

Partially it is only the environmental parameters and the installation options that influence the selection of the system. In doing so, each system has its specific advantages in terms of conditioning the products.

For small batches of up to approx. 300 litres, we recommend horizontally aligned mixers with single-side bearing and seal. These mixers can be very easily cleaned by means of hinged, drive-sided head ends.

Designs with completely removable agitators are used where absolute cleaning of the machine is important. In addition, choppers / cutting heads integrated into the back wall serve to split up agglomerates.

Large batches are homogenised in vertical cylinders or conical mixers. In this respect, AVA helix systems serve to considerably reduce mixing times and improve homogeneity.

Large batches of 40 - 60 t are manufactured with a conical central tube mixing system of approx. 20,000 litres. For these systems, only a minimal drive performance is required. In addition, discharge ratios of up to 99.9% are achieved.

The vertical conical mixers have proven themselves superbly in heating e.g. iron powder. The heat transfer values (K values) of AVA conical mixers are highly efficient.
