Mixing technology


Precise results each and every batch

The production of high quality concrete products requires mixing technology that delivers precise results each and  very batch. HESS GROUP SM-Series mixing technology consistently  dispenses the perfect concrete mix in the shortest time. HESS GROUP offers complete mixing plant technology including dosing units for aggregates, cement, and color-blended concrete.

The SM-Series of planetary mixers feature:

  • Self-supporting construction with lower and upper frame
  • Separate drives (for tool plate and mixing stars)
  • Stopping and starting the loaded mixer is possible anytime.
  • Two large double doors for easy and safe clean-up and maintenance operations
  • Two large discharge openings in the mixer floor
  • Clean-out time significantly reduced due to  minimal deposit build-up (special water inlets)
  • Special cement input device allows dust-free cement adding operation (optional)
  • High mixing intensity most favorable for low cement/water ratio concrete mix designs
