The solid building site mixer: D20

Mixer D20 is a robust allrounder for processing dry mortar products with a granularity of up to 4 mm. It is the bestselling mixer in this class and, depending on the version, rationalizes the processing of decorative renders, bricklaying mortar or fine concrete.

The 230V version specializes in the processing of decorative renders and thus is fitted with the versatile standard mixing chamber with plain bearing. It is also available in a 400V version which shows its prowess in the processing of heavy materials such as bricklaying mortar or fine concrete. In this case the ball bearing-mounted fine concrete mixing chamber is used.

The D20 is filled with bagged material as standard and offers impressively homogenous blending. The large material container is perfect for building sites.

Well-organized controls, easy dismantling and maintenance combine to make the D20 very easy to handle.


Tried-and-tested solid steel components ensure a long service life and easy maintenance.
