is a life breadth of any countries economy. Asphalt plays pivotal role
in developing and constructing infrastructures like roads, highways,
airport runways etc. Drum mix plants makes asphalt continuously and can
store the asphalt for several days in heated storage soils. Drum mix
asphalt plants are either mobile or stationary. Mobile drum mix can
shift themselves to the job site itself whereas stationary plants uses
other asphalt carrying vehicles to reach the desired destinations.
The asphalt plant uses a cold aggregate feeder whose each bin has an
independent conveyor belt. For feeding the aggregate at a uniform and
predetermined rate it uses a hollow shaft gearbox. The drum is supplied
with cold aggregate from the feeder using an electronic high-pressure
jet burner. The asphalt tank is fully insulated and is equipped with
separate low-pressure electronic burners to heat the asphalt.
The control cabin with an electronic control panel operates the entire
plant. To transport the mixed material from the thermo drum into the
hydraulic storage hopper the asphalt plant uses a loadout hot conveyor.
At the end of conveyor there is a scraper plate to scrape out the mixed
material from the loadout conveyor.
Mobile drum mix plant for bituminous macadam comprises of conveyor
bitumen pump, a filler unit and a filler blower. For proper heating of
the aggregate with the minimum heat loss, dryer is accurately
constructed. The filler units and blower are made from steel plates.
