The highly mobile BHS concrete mixing plants stand up to adverse ambient conditions, frequent changes of location and permanent operation at maximum load in the harshest of construction conditions. Both the MONOMIX variant with one mixer and the TWINMIX as a dual plant are thus investments that offer value stability and high availability. At the heart of every plant is the twin-shaft batch mixer that has proven its worth thousands of times over.
The BHS concrete mixing plant consists of modular container units. The robust design ensures stability and mobility, even when the mixer is frequently moved to new locations. The system is fully pre-installed and wired at the factory. All interfaces are equipped with plug-in connectors. The system is installed without a foundation. It can be installed or dismantled in a single day. The transport width of the containers is 3 m.
In the case of portable concrete mixing plants, the need for mobility often comes at a price: poor accessibility and high maintenance effort. When you consider that the plant’s primary function is to reliably produce concrete at low cost, this is a heavy price to pay. For that reason, the BHS container system has been designed to deliver mobility without any of the associated disadvantages.
The BHS concrete mixing system in container form can also be operated as a stationary plant. Compared to conventional systems, the associated costs are much lower. This is achieved, for example, thanks to shorter installation times and because there is no need for a concrete foundation or ramps. In addition, mobile systems make the task of securing the necessary permits easier. If the chosen location proves unsuitable after a few years, the system can moved to a new site quickly.
The BHS concrete mixing system in container design can also be tailored to meet the client’s individual needs. Aggregates, binders and additives can be stored and metered based on the customer’s specifications.
Four-, six- and eight-chamber hoppers as well as several special models are available depending on the specific task and space available. The hoppers can be positioned in a longitudinal direction to the ascending conveyor or at a 90° angle.
The individual chambers of the hopper can be fitted with bunker covers that can be operated hydraulically or using an electric motor. These are manufactured to be torsion resistant and can also be insulated.
Grate covers are available to prevent impurities from getting into the hopper, which can be pivoted on the infeed edge.
There are a range of configuration options available for twin-shaft batch mixers to accommodate different applications. Please refer to the “Twin-shaft batch mixer” brochure for more information.
The system can be equipped with a high-pressure cleaning unit to efficiently clean the mixer and, as an option, the discharge hopper as well.
An insulated version of each of the modules is available specially for winter operation.
If needed, the mixing plant can be retrofitted with a hot-air heater and a hot-water system.
It is possible to add additional devices to the system to meter special components of the formulation. This includes flake ice, fibers, silica fume and hot steam.
