The SBM EUROMIX 1600 NOVA mobile concrete mixing plant was shown at bauma in two versions, the semi-mobile and stationary options.

SBM concrete mixing plants
For the concrete division of SBM Mineral Processing, semi-mobile and stationary DYNAMIX 2500, VARIOMIX, LINEMIX, and TOWERMIX concrete mixing plants were exhibited in various configurations as detailed scale models.
Two mixing units from the EUROMIX 1600 NOVA mobile concrete mixing plant, launched in November, shared the outdoor stand. Visitors were able to explore the space available for maintenance work inside the smallest mobile SBM concrete plant. Virtually unchanged external dimensions allow easy transport on flatbed trailers. In combination with modularly expandable silo units, horizontal rock hoppers, and the control cabin, the complete mobile mixing plant can be set up and ready for operation in just eight hours using a mobile crane, according to SBM.
Equipped with the BHS DKX 1.67 twin-shaft mixer with a solid concrete output of 80 m³/h, the plant is suitable for small to medium-sized construction sites with a daily requirement of up to 800 m³ of concrete or liquid soils for backfilling. The ‘winter package’ allows the EUROMIX 1600 NOVA to work in any weather condition and can be used as a temporary supplement to stationary plants to produce high-quality mixes — including special and recycled concrete — or as a space-saving permanent solution in precast production.
From automation to autonomy
In a pilot project, SBM Mineral Processing is currently working with an operating company and software specialists in the concrete sector on new solutions that will enable largely autonomous operation of individual process stages or complete mixing plants, including upstream material logistics.
The focus of this project is on reducing the workload of the responsible personnel, such as the mixing engineer in routine operation and at off-peak times. In further development stages, production, which is already largely automated, will be further optimized by means of comprehensive sensor-based monitoring of the raw materials (moisture, temperature, etc.) and the mixing process (mixing moisture, consistency), which will make it possible to adjust the concrete recipes at short notice.
As a first step, autonomous concrete delivery to different vehicles based on pre-ordered recipes has now been implemented. Once the truck mixer/tipper is correctly positioned under the delivery hopper, the driver releases the delivery. Special sensors in the hopper monitor the smooth filling of the concrete batches. Once the delivery vehicle has left the area and the passage has been secured, the mixer and hopper are automatically washed if necessary — for example, in the case of fibre or coloured concrete — or at a pre-set interval. Sensors monitor the swivelling range of the cleaning hopper — once cleaning is complete, the passage is reactivated via a barrier.
