Industries and applications
Whether you process paper chemicals, polymer solutions, pigment dispersions or dairy products, the key question is which product properties the mixing process must achieve. Cavitron develops rotor-stator machines and processing plants for dispersing, emulsifying, homogenising and mixing. The following applications illustrate the criteria that determine process design.
Paper industry
Emulsifying ASA in starch size
For paper sizing, ASA and starch size must be combined under controlled conditions to form an emulsion. Metering, phase ratio and emulsification conditions determine preparation quality.
Preparing bentonite suspensions
Uniform wetting and dispersion create the conditions for bentonite hydration. The dispersion stage and subsequent maturation time must suit the concentration and intended use in paper production.
Bitumen and plastics
Producing polymer-modified bitumen
In PmB production, polymers are incorporated into bitumen. Dispersion, temperature control and swelling time must be matched to the polymer type, concentration and target binder properties.
Polymer-modified bitumen production
Preparing polybutadiene rubber in styrene
The process chain combines rubber size reduction and dispersion with subsequent dissolution in styrene. Feed size, rubber content and the development of viscosity determine equipment selection.
Food industry
Dispersing and homogenising dairy products
Incorporating powders and producing premixes requires effective wetting, lump breakdown and uniform distribution. Hygienic design and cleaning are adapted to the product. Any required high-pressure homogenisation or heat treatment remains a separate process stage.
Paints, coatings and resin systems
Dispersing carbon black in solvents
The task is to wet carbon black and break down agglomerates in a controlled manner. Carbon black grade, solids content, viscosity and temperature limits determine the required energy input and subsequent processing.
Incorporating fumed silica into polyester resins
Powder addition, wetting and dispersion intensity must work together to achieve the required rheology. The formulation’s viscosity and thixotropic behaviour, together with its permissible thermal load, are decisive.
Dispersing aluminium powders and pastes
Metallic pigments require processing adapted to particle shape and surface treatment. Dispersion should break down agglomerates without unnecessarily changing the pigment properties that matter in the application.
Chemical industry and oleochemicals
Emulsifying polymers and resins
To produce reproducible emulsions, prepared polymer or resin phases are combined with the continuous phase. Phase ratio, emulsifier system, temperature and viscosity define the design conditions.
Polymer and resin emulsification
Saponifying oils and fats with sodium hydroxide
Intensive distribution of the oil or fat phase and the alkali improves contact between the phases. Stoichiometry, temperature and residence time are also decisive for reaction conversion.
Which configuration suits your process?
For a technical assessment, we need the materials and concentrations, required throughput, viscosity and temperature range, and target product properties. Please also describe the existing bottleneck and requirements for materials of construction, cleaning and explosion protection.
This information helps establish whether a Cavitron CD in-line processor or a tailored processing plant suits your task and which trials are needed for equipment selection.
