Economical Mixing with GBM Batch Mixer

The GBM series offers impressive processing, flexibility and reliability. Optimum configuration of the mixer housing and paddle shape as well as the favourable positioning of the infeed ducts for micro-components mean the mixing process is three to four times shorter than in comparable devices.

The GBM single-shaft mixer has been designed based on more than 100 years of experience in building mixers. The modular design ensures the best possible adaptation to the requirements of the process.

Bolt-on mixing paddles are used in the standard version. Optionally, the GBM mixer can be equipped with ploughshares or spiral blades.

Principle of Operation

Paddle batch mixer principle of operation

The rotating paddles divide and blend sequentially the mass of product and generate a quick and intense movement of each particle through the mixing chamber (convection). 

Due to the defined angle of the paddles the mixer has an excellent axial and radial dispersion. 

Using choppers additional energy is applied to the product to break up lumps and ensure the dispersion of any agglomerates or liquids. Choppers are also used for granulation processes as well. 

The paddle design means product is transported to the outlet valve for a quick and complete discharge of the mixer.
