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.
Output capacity: in the range of 30 TPH to 120 TPH.
MULTI BIN COLD FEED SYSTEM
Stores, meters and supply in required proportion different size of cold virgin aggregates for the production process.
Oversized aggregates from feeder bins are removed by single deck scalping screen before they are fed into drum through slinger conveyor.
Transfers the screened aggregates from the feeder bins to the rotary drum through inlet beneath the burner.
Cold aggregates fed by slinger conveyor are dried & heated in the primary section and are mixed with asphalt & filler material in the secondary section to produce the quality hotmix which is delivered to load out conveyor.
Produces the required flame through proper air fuel ratio and builds the necessary temperature inside the drum for drying and heating of the aggregates.
LOAD OUT CONVEYOR
Transfers the hotmix output received for the drum directly to the truck or storage silo.
Stores, meters and delivers the asphalt in required proportion to the mixing section of the drum. Asphalt is sprayed uniformly in the mixing zone for accurate coating on aggregates.
MINERAL FILLER UNIT
Stores, meters & delivers the mineral filler material in required proportion to the mixing section of the drum.
FUEL SERVICE TANK
Stores the fuel (LDO/ Diesel) and supplies the dryer and asphalt tank burners at required pressure by fuel pumping station.
WET SCRUBBER UNIT
Pollution control unit that absorbs & traps the hazardous gases and dust particles escaping along with the exhaust gases.
It is centralized control panel from where all the operations of the asphalt drum mix plant components are controlled.
