In the production of precast concrete components, maintaining high levels of mixture homogeneity is essential, regardless of the formula. Today this becomes even more important in light of highly demanding concrete formulas. With our DKX twin-shaft batch mixer you're on the safe side when it comes to these requirements.

The BHS twin-shaft batch mixer (type DKX) features outstanding mixing capabilities thanks to its three-dimensional mixing motion. It can also meet the challenging demands of the precast concrete industry. The mixing tools produce highly intense relative movements throughout the entire mixture. Bonding agents and chemical admixtures undergo optimum dissolution. Additives such as pigments or fibers are distributed quickly and evenly. Batch upon batch, your mixing results will always be extremely homogeneous. Agglomerations are disintegrated without damaging mixture particles. In addition, two separate discharge openings are available as optional add-ons.

These mixers are also more wear-resistant and usually have lower specific power consumption than mixers with vertically arranged mixing tools. They can also reliably mix partial batches of less than 10% of the mixer capacity. An ever-growing number of references from the precast concrete industry testify to the advantages of twin-shaft batch mixing technology over two-dimensional mixing systems. These mixers can also easily produce formulas for concrete blocks, face concrete, colored concrete, high-performance concrete (including UHPC) or self-consolidating concrete (SCC).
