Technology
AER-A-MIX
AER-A-MIX improves the design and efficiency of the Speedmullor by modifying its mulling principle: intensive aerators action takes the place of the mulling wheels.
Existing Speedmullors in operation can be converted in the field by incorporating the high efficiency aerators. FONTEC builds new AER-A-MIX mixers and converts existing Speedmullors 100B and 85B.
Conversion
From Speedmullor 100B or 85B to AER-A-MIX
The advantages
- Improves sand quality.
- Increases hourly capacity.
- Provides aerated, flowable sand.
- Eliminates the need of premixing the additives without water.
- Faster and immediate dispersion of water and additives into the sand.
- In conjunction with FONTEC’s low pressure and low density bond injection system, build-up inside the mixer is minimized, providing a cleaner environment.
- More efficient use of active clay: according to FONTEC, consumption is reduced by as much as 20 percent.
