Mixing Systems

When processing multi-component materials, homogenous mixing of the components becomes extremely important. Wide differences in media viscosity, short pot life, components which are difficult to mix etc., require different mixing systems.

DOPAG offers dynamic mixing systems, static mixing systems, static-dynamic mixing, system as well as mixer element monitoring for static-dynamic mixing systems.


  • Mixers of this type are used if difficult media with dissimilar viscosities and with a relatively long pot life have to be mixed.

    Are usually used within a mixing ratio of 100:100 to 100:10.

    Pneumatic or electric motors are used to rotate the mixer elements.

    Optional static-dynamic mixing systems can be assembled with mixer element monitoring.
  • Mixer Element Monitoring
  • Dynamic mixers are generally used to process multi component materials if

    there is a significant difference between the volumes of the different components to be mixed, as an example, a mixing ratio of 100:5
    the viscosities of the components to be mixed are very different
    the mixed material has a very short pot life
    very low flow rates are required
    DOPAG dynamic mixer is compact in construction and is available with 5 different mixing chamber volumes. The rotor situated in the mixing chamber can easily be disassembled. The valve connections can be swivelled so that the optimal hose direction can be chosen. The inlet valve of the A component has been positioned such that it is impossible for mixed material to come into contact with the rotor seals. This confi guration not only increases the protection of the rotor seals but also increases the functional security of the dynamic mixer.
    Mixing Chamber
    The volume and characteristics of the mixing chamber depend on the flow rate and miscibility of the material. The material inlet valves are mounted onto the mixing chamber at a specific angle so as to be flush with the inner surface. This arrangement helps to avoid dead space where air bubbles or the remainders of mixed, undelivered material could accumulate.It is important to ensure that the mixing chamber is completely exhausted during the metering process to prevent material from dripping after metering has finished.

    Depending on the application conditions and flow rates the dynamic mixer can be fitted with different sizes of inlet valves. They are all made of stainless steel. If required this mixing system can be fitted with recirculation valves. With this configuration, the material can be kept in motion by means of a bypass, which minimises the risk of failure since the mixing ratio remains controlled and pressure drops are reduced. In addition, the bypass has the advantage that any possible sedimentation of fillers can be avoided. Optionally, the working position of each of the inlet valves can be monitored by use of a sensor.
