Sistemi FLOMAC - vengono impiegati nella lavorazione di uno o più materiali. I materiali vengono depositati in un silo e trasportati in una tramoggia posta all’interno dell’unità di premiscelazione attraverso una coclea indipendente. Da qui i materiali vengono introdotti nella mescola per mezzo di una pressione positiva nel sistema di trasporto pneumatico. .

| Warm mix additive from AkzoNobel |
AkzoNobel recently announced an addition to their range of bitumen additives with the development of Rediset™ WMX. This new warm mix system significantly reduces the mixing and application temperatures whilst enhancing the moisture resistance properties of the mix.
Rediset™ WMX comes in a free flowing pastille form which can be easily added to the mixing unit via the Flomac dosing system or to the bitumen, at approx 1kg/t of the final mix. Other benefits of warm mix with Rediset™ WMX include:
