GCM Continuous Mixer

The GCM mixer is suitable for mixing a wide range of powders, flakes and granulates and viscous products also in combination with spraying of liquids. The GCM is easy to clean and can also be combined with a heating or cooling jacket.

Continuous mixing processes are a powerful alternative to traditional batch processes. They combine mixing efficiency and high throughput with low space requirements. 

Principle of operation


The infeed ingredients are continuously weighed by GERICKE feeding systems and added into the mixing chamber in accordance with the recipe. GCM continuous mixers offer the optimum combination of radial and axial mixing (dispersion) depending on the task and the type of component. 

The axial dispersion compensates for variations in feed concentration and results in a defined residence time distribution.

The radial dispersion is defined as mixing by rotation. The forward motion causes intensive material transport and forms a fluidized zone. This allows also for the addition of liquids.

Area of applications

Solid-solid blending

Product properties such as very fine, wide particle size distribution or variable specific density can be handled. With the optimum ratio of mixing volume to throughput the mixing process is gentle, fast and respects the different properties of the bulk material.


  • preserving sugar
  • milk powder with vitamins and mineral additives
  • spices
  • additives with plastic granulates
  • raw materials for ceramic extrusions

Solid with liquid additives

Bulk materials are sprayed with aromas, binding agents or other liquids or the liquid is poured on. The prime concern is preventing the formation of agglomerates, absorption or liquid binding with the product. Mixer size, number and location of spray points, nozzles, residence time etc. are fully customizable.


  • instant coffee with aroma
  • mixing muesli bars
  • spreads
  • substrates with expanded glass beads and binders

Liquid with solids

The ratio between solid and liquid can be 50% or greater. The mixed product remains in a liquid or viscous phase. GCM mixers can be cleaned quickly with the easily accessible mixing chamber.
