As an overview we can mention the following general applications:
Gentle mixing of free flowing and segregative powders, pastes and liquids
Addition of liquids to powders by means of spray nozzle or intensifier
Intensive dispersion of liquids and solids by means of the intensifier
Granulation by moisture addition
Heating and cooling
Drying by means of heat input in combination with vacuum and possible liquid recovery
Chemical reactions
De-aeration of paste
Coating of solids with liquids (with intensifier)
Life hopper for sticky or segregative products
Agitated hopper to feed dryers like Fluid bed with or without back mixing
Intensifier Rotor
The conical mixer can be equipped with a high speed rotor for liquid addition or for de-lumping products. Rotating up to 20m/s, this rotor creates a vortex effect and injects the liquid through the paddles directly in the product resulting in an excellent dispersion or coating. By spraying the liquid in the mass itself in a vortex, we avoid over-moistening of particles and risk of sticking phenomena on the vessel. This intensifier can replace several lump breakers.
The Vrieco-Nauta® conical mixer is a batch mixer which has a typical process sequence. The sequence can be as follows:
Charging of mixer from the top, manually, big bag, pneumatic or mechanical conveying
After the mixer is charged the mixing process starts. The mixing time is depending on product characteristics, mixing accuracy and batch size
Discharging of the mixer takes place via the bottom by means of a manual or automated discharge valve. From here the product is packed or fed to the next process step like tabletting, extrusion, screening etc.
Some typical installation principals of the Vrieco-Nauta® conical mixer:
