Precast concrete for floorboards


Twin-shaft batch mixer of type DKX 3,00

Components made of precast concrete have become an indispensable part of the building materials industry. The Dutch manufacturer Van Nieuwpoort Prefab has commissioned BHS-Sonthofen and Loke BV to equip an existing plant with a BHS twin-shaft batch mixer of type DKX 3,00 and to optimize the plant. Since then, optimum mixing results have been achieved for concrete used in the production of floorboards and the plant output has been significantly increased.

Concrete floorboards have various benefits that render them highly suitable for residential, business, and commercial buildings. Good sound insulation makes for comfortable living arrangements, and the potential benefits of good thermal insulation further endorse precast concrete floorboards as a sustainable building option. So it is of no surprise that precast concrete floors from Van Nieuwpoort Prefab have been popular for over 100 years. The Netherlands-based expert in building materials and home development is committed to the continuous investment in new construction technologies and efficient production methods at its site in Kampen.

Improved mixing results and high production performance

To ensure the high quality of the concrete needed for the production of floorboards, van Nieuwpoort relies on the twin-shaft batch mixer of type DKX 3,00 from BHS-Sonthofen. This replaced a previously used mixer, which could not produce the concrete with the required homogeneity. The advantages of the BHS mixer, considered to be the benchmark in the industry for good reason, quickly became clear: With the same size of mixer, the homogeneity of the concrete has been significantly improved. One of the reasons for this is the three-dimensional mixing principle of the DKX, which leads to a more intensive material exchange. This takes place in the highly turbulent overlapping area of the two mixing circuits. In this way, the BHS twin-shaft batch mixer produces mixtures of consistently high homogeneity in a short time. Furthermore, the size and design of the mixing blades play an important role.

Van Nieuwpoort relies on BHS-Sonthofen

The main objective was to increase production capacity. “Thanks to the new mixing technology, the customer produces the same number of floorboards in 16 hours as before in 24 hours,” explains Peter Loke, Managing Director of Loke B.V. This significant increase in productivity not only benefits Nieuwpoort, but also suits Loke and BHS-Sonthofen.
