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
