We offer a laboratory mixer (type DKX 0.06), whose 60-liter mixing volume represents a suitably scaled-down load of our twin-shaft batch mixer. It is designed to emulate production machinery down to every detail.

Twin-shaft batch mixer (DKX)

Versatile high-performance mixer

Concrete admixtures and additives are distributed quickly, evenly and effectively. The fields of application of the twin-shaft batch mixer range from fine to coarse, from hot to cold, from light to heavy, and from wet to dry.

The right feature set for any application:

Optilong wear protection

Optilong is our special, durable wear protection. The variable hardness of the individual tile rows ensures uniform abrasion across all wear zones.

Smooth mixing tools

Smooth mixing tools reduce adhesions to a minimum, even when processing sticky mixtures.

Twin mixing mechanism

A twin mixing mechanism processes the mixture with higher shear forces.

Monitoring the mixing operation

Precise monitoring of the mixing process is possible with the help of various components. Depending on customer requirements, we can equip our mixers with probes for consistency or for temperature measurement, a device for taking samples, or a video camera.

Laboratory mixer

Big things comes in small packages – this mixer is optimally suited for R&D in the concrete laboratory
