Concrete Tranportation

An existing paving stone factory wanted to manufacture colormix from an existing mixer with 1 discharge opening. The distance to the paving stone machine was relatively long and not in a straight line which made it a challenge to find an optimal solution.

By using a Haarup Duo-speed with bottom discharge which is specially designed for dry concrete and used for this type of machines we could manage the relatively long distance with several curves within the cycle time of the mixer. The solution was combined with concrete hoppers installed with discharge belts which dose on a belt which empties directly in the paving stone machine. Along the hoppers a gangway is made to make cleaning of hoppers easier.

The solution meant that the customer by means of an existing mixer with one discharge opening could manufacture colormix even though the distance to the paving stone machine was relatively long and the space tight.
