Stationary Asphalt Drum Mix Plant

Stationary Asphalt Drum Mix Plant

The ingredients of the hotmix, in required proportion, are continuously fed to the rotating drum in drying & mixing zones and the discharge end of the drum delivers continuous output of the hotmix. The main ingredients of hotmix are virgin cold aggregates of different grades, asphalt (bitumen) and mineral fillers.

The main components of Asphalt Drum Mix Plant are Multiple Cold Aggregate Feeder Bins, Single Deck Scalping Screen, Slinger Conveyor, Rotary Drum, Burner, Load out Conveyor, Asphalt Tank, Mineral Filler Unit, Fuel Service Tank, Wet Scrubber and Control Panel. In the process, the cold aggregates of different grades that are stored in the Multiple feeder bins are transferred in required proportion to the primary section of the rotary drum through slinger conveyor. The burner fitted on the in feed side of the drum produce appropriate flame to remove the moisture from the aggregates and heat the dried aggregates to the desired temperature in the primary section of the drum. The hot aggregates then travel down the secondary section where they are mixed & coated with the asphalt & filler material. The asphalt and filler material are pumped in the secondary section in predetermined proportion from asphalt tank and mineral filler unit respectively. These hotmix from the drum is then transferred to truck through load out conveyor.
