High shear mixer Extrudomix

The Extrudomix high shear mixer is an efficient, low to medium pressure extruder that kneads, mixes and extrudes in one continuous process; as a standalone unit or in combination with other process equipment.

The Extrudomix is highly suited to mixing solids and liquids into very viscous and homogeneous pastes as well as plastic masses.

The Extrudomix has a single horizontal shaft with blade segments arranged in a spiral pattern that move the material through the chamber. Material is fed into the housing at one end and forced forward by the rotating blade segments until it comes in contact with the stationary anvil. Stationary anvils attached to the housing and inserted between the rotating blade segments prevent the material from rotating with the shaft. The resulting effect is continuous kneading and mixing, followed by extrusion through a variety of die which are available in different shapes and sizes.

The Extrudomix has better particle dispersion in comparison to higher pressure systems. It is also less expensive to buy and less expensive to operate.

The Extrudomix can be used for a variety of applications, including:

  • Mixing base powders with liquids to form uniform pastes
  • Homogenising filter cakes
  • Blending wet material with powders or liquids
  • Homogenising powders with liquids into a plastic mass followed by extrusion
  • Pre-feeding of caked masses


  • Continuous, intensive mixing of viscous materials
  • Compact design
  • Mixing, kneading and extrusion in one unit
  • Homogeneous mixing of very viscous pastes and plastic masses
  • A variety of extrusion plates with different shapes and sizes (diameters up to 5 - 6 mm)
  • Heating / cooling jackets and hollow shafts available on request
  • Additional shear capabilities
  • Batch mixing alternative available on request

The Extrudomix is available in 6 models, with rotor diameters ranging from 150 mm to 600 mm. Their basic characteristics are described below. Detailed information is available on request.
