Speedmullor
Intensive mixer with mulling wheels, built on the original Fenwick drawings and patterns. Six models: 100-270, 100-220, 85-220, 85-180, 75 and 55.
| Model | Max. batch (kg) | Max. hourly capacity (t) | Main motor (CV-HP) | Cooling blower (CV-HP) |
|---|---|---|---|---|
| 100-270 | 2250 | 100 | 270 | 15 |
| 100-220 | 2000 | 85 | 220 | 15 |
| 85-220 | 1600 | 68 | 220 | 10 |
| 85-180 | 1450 | 60 | 180 | 10 |
| 75 | 850 | 36 | 125 | 7,5 |
| 55 | 550 | 25 | 75 | 5,5 |
Batch capacity, hourly capacity and cycle times are approximate and depend upon sand formulation, degree of cooling desired and installation of moisture or compactability controller operating in real time.
Series
AER-A-MIX
AER-A-MIX improves the design and efficiency of the Speedmullor: intensive aerators action takes the place of the mulling wheels. Five models: 100-270, 100-220, 85-220, 85-180 and 75. Existing Speedmullors 100B and 85B can be converted into AER-A-MIX.
