Agitators

With more than 50 years of experience, VMI designs and manufactures a full range of agitators for various types of mixing operations. Whether for dilution, dissolution, suspension, homogenization, dispersion or emulsion, our teams will very carefully study your processes in order to better define the sizing, power and speed parameters which are best suitable to liquid-liquid or solid-liquid mixtures with a strong concern for quality and productivity.

A wide range of agitator blades, with radial or axial effects, helps optimize phenomena related to movement and shearing, whatever are the required capacities and the rheological characteristics of target products.

Agitators from VMI manage 4 main agitation families:

  • suspension and homogenization (liquid / solid)
    CYNABLOC agitators are known for their high pumping efficiency. Thanks to the performance of propellers with axial effects, the agitators are perfect for homogenization and suspension operations.
    The range of HELIBLOC agitators corresponds to homogenization or suspension operations for high-capacity containers. The agitator is set up in a lateral position on the bowl ferrule.
  • Dispersion (liquid / solid)
    Dedicated to dispersion operations, the DIRECT (for small quantities) and EMPATEUR (for larger quantities) agitators are characterized by their high agitation speed combined with a dispersion turbine with radial effects.
    The BOWL BOTTOM DISPERSER (DFC) is located on the bowl’s bottom. It may be associated with an agitator of the CYNABLOC type located on the bowl’s roof and ensuring a pumping function.
  • Dissolution and dilution-homogenisation (liquid / liquid)
    The DYNABLOC agitators manage dissolution, dilution or homogenization operations for bowls of intermediate capacity. To ensure those operations, they are associated with turbines combining pumping and shearing capabilities.
  • Emulsion (liquid / liquid)
    The ULTRAMIX agitator is perfect for all emulsion operations and guarantees a high stability of phases thanks to its intense shearing. The stator geometry is adapted to the viscosity of products.
    The BOWL BOTTOM EMULSIFIER (EFC) is made of a rotor stator and may be associated with an agitator of the Cynabloc type located on the bowl’s roof and ensuring the circulation or priming operations of the EFC.

For relatively significant production runs (from a few hundred litres per hour and up to several tens of thousands of litres per hour), continuous mixing is undeniably an interesting alternative for batch mixing operations. VMI offers continuous mixers made of several levels depending on the desired homogeneity for the mixing and the number of ingredients to be added:

  • The EHL agitator is made of one or more rotors/stators and allows for emulsion or smoothing operations.
  • The GYROFLUX agitator manages all mixing operations (dispersion at high speed, dilution, etc.)

Extract for some of our agitators:

  • ATEX compliance
  • Variable speed drive: with compressed-air motor or converter integrated to the motor
  • Turbines at different levels for high volume bowls
  • Sealing: sealing lip for air pressure
  • Pressure between -0.8 and 2 bars
