Double shaft mixer

The open double shaft mixer (DWMO) mixes and kneads different components in the open mixing trough. The mixing knives are freely adjustable. Due to the strong mixing-kneading effect, water and vapour are very well incorporated.

If the focus is on mixing, the double shaft mixer DWM is used. Ceramic bodies are kneaded in the auger front section very intensely.

When it comes to vacuum moulding, the machine with a vacuum chamber becomes a vacuum double shaft mixer. With this solution the ceramic body is chopped up very finely and well sealed toward the mixing zone. This solution guarantees the safe and strong moulding vacuum Petersen Service is known for.
