Extrudomix Mixer/Extruder
The Extrudomix is a high-shear mixer/extruder for continuous or batch mixing, kneading and low- to medium-pressure extrusion. It processes powders and liquids into homogeneous, highly viscous pastes or plastic masses without separate pre-mixing. The unit can operate independently or as part of a complete extrusion system, with optional heating or cooling for precise temperature control.
Key benefits
- Mixing, kneading and extrusion combined in one compact extruder
- Intensive mixing of viscous materials and plastic masses
- Suitable for both continuous and batch processes
- Various extrusion plates with different shapes and diameters (up to 5–6 mm)
- Heating/cooling jackets and hollow shafts available
- Additional shear capability for demanding applications
- Easy integration with feeders, dosing, extrusion and drying equipment
Principle of operation
The Extrudomix extruder features a horizontal shaft with blade segments arranged in a spiral pattern to move the material through the chamber. Stationary anvils, mounted inside the housing and positioned between the rotating blades, prevent the material from turning with the shaft. This design ensures continuous kneading, mixing and extrusion through precision dies available in various shapes and sizes.
For temperature-sensitive materials, the housing can be equipped with heating or cooling jackets, while hollow shafts allow improved thermal control. Compared to high-pressure extrusion systems, the Extrudomix extruder provides better particle dispersion, lower energy consumption, and reduced operating costs.
Process flexibility
The Extrudomix extruder is suitable for a wide range of industrial processes, including:
- Mixing powders with liquids into uniform pastes
- Mixing wet materials with powders or liquids
- Homogenising filter cakes
- Producing plastic masses with controlled extrusion
- Pre-conditioning wet products for fluid bed drying
- Processing caulking compounds, soaps, sugars and yeasts
