Single-shaft continuous mixer (MFKG)

Intense mixing of dry or moist fine materials

The BHS single-shaft continuous mixer (MFKG) is a powerful, easy-to-maintain solution for continuous mixing processes, particularly those with fine aggregates. The mixer is suitable for the continuous production of dry, paste-like, moist or pumpable mixtures.

The design of the mixer inlet, the shape and arrangement of the mixing tools, and the selection of the appropriate speed ensure a consistently high mixture quality. The material to be mixed is accelerated forcefully by the mixing tools. The energy input causes highly turbulent relative movements in the mixture throughout the entire volume of the mixer. Any agglomeration of material is reliably broken down by shear forces, eliminating the need for additional agitators. This means that consistent, homogeneous mixing results can be achieved in a very short time.

In the single-shaft continuous mixer (MFKG), the mixing components undergo forceful acceleration and intense mixing.

The self-cleaning rubber trough is another special feature of the BHS mixer. The pulsating motion of the rubber jacket prevents hardened mixed material from caking on the trough wall. This also helps to reduce energy consumption and protects the mixing tools from wear.

Our single-shaft batch mixers have proven their value in countless applications. Mixers for continuous processing are available for the performance range from 10 to 700 t/h. Precision dosing technology is essential for continuous mixing; we offer this component as well as complete systems.

Twin mixing plant: Two different mixing procedures in one system

A new unparalleled mixing plant from BHS-Sonthofen has been in operation of late at Nikolaus Müller Kalkwerk-Natursteinwerke (Müllerkalk) in Rhineland-Palatinate close to the Belgian border: It combines the continuous moistening of agricultural lime and the batch production of mixed binders for ground stabilization measures. The new plant opens up new markets for Müllerkalk, thereby compensating for the somewhat seasonally fluctuating lime market. The fully automatic loading is a special feature: it is available approximately 24 hours a day, 7 days a week.
