Combimix processes (DKXC)

Combimix processes (DKXC)

The patented Combimix system transforms the twin-shaft batch mixer (DKX) into a mixer that operates continuously according to the proven three-dimensional mixing principle. This results in a more intense mixing effect and a significantly longer average retention time compared to conventional continuous mixers. The material is extracted at the same rate as the input material is fed into the system.

BHS Combimix process for processing clay-and-rock mixtures in quarries

This nomination video for the German Resources Efficiency Award 2016 introduces the BHS Combimix process for processing clay-and-rock mixtures at the Mönsheim quarry operated by MSW Mineralstoffwerke Südwest. 

Highlights

Advantages compared to wet processing

• No introduction of moisture into the aggregates
• No wet sieving
• No sludge processing
• All materials are recycled, saving landfill space
• Compact system also available as a semi-mobile version
• High level of rock reclamation
• Possible to screen out material smaller than 5 mm

Advantages compared to conventional continuous mixers

• Continuous mixing process with a defined mixing time, which helps to reduce consumption of expensive burnt lime
• Three-dimensional mixing principle
• Consistently high mixture homogeneity
• High throughput rates
• Low wear
