Three-dimensional mixing with the BHS twin-shaft batch mixer (DKX)

Our twin-shaft batch mixer (type DKX) rapidly produces mixtures with consistently high levels of homogeneity. It is a well-proven, highly reliable solution for industrial mixing processes (especially mixing of minerals) with medium to high output requirements. The machine is a classical compulsory mixer.

The BHS twin-shaft batch mixer has been successfully employed around the world for decades in the concrete industry. But this mixer has also proven to be an outstanding solution for numerous other applications. Our customers benefit from this wealth of experience. They receive a product that is well-proven, highly cost-effective and reflects the state of the art.

The twin-shaft batch mixer moves the entire mixture in a three-dimensional spiral motion. There is also an intense exchange of materials in the turbulent zone where the two mixing cycles overlap. The energy applied is optimally converted into intense relative movements of the entire mixture. Thanks to the optimized design and arrangement of the mixing tools, you will achieve consistently outstanding mixture homogeneity batch by batch, with very short mixing cycles.

The graphics below use a realistic DEM simulation to show the development of mixture homogeneity during the mixing process in a BHS twin-shaft batch mixer.

Twin-Shaft Mixing - Fast cycles plus high powder and power economy

The objective of any mixing process is to distribute and blend materials with different characteristics and quantities as evenly as possible, resulting in a homogenous mixture. Introducing proportional movement with the optimal intensity yields effective, homogeneous mixing results. Much like stirring, simple one-directional movement with inadequate acceleration of the materials would not achieve the same mixing results.

Mixing special concretes

As a result of recent new developments throughout the concrete industry over the past years, the re-quirements placed on the concrete production process, as well as the complexity of the mixing tasks, have considerably increased. This situation confronts suppliers of mixing machines with the tasks of systematically acquiring new knowledge on the operation and the functioning of their machines, and of developing suitable solutions for the challenges that arise.
