Drying and mixing drum

The portable dryer is the main unit of the mobile asphalt drum mix plant. It assures efficiency in uniformly heating and also drying the aggregates. Rotary cylinder dryer drum is mounted on sturdy platform driven by an AC motor fitted with sprocket and chain equipped with high pressure jet burner, flights, bitumen and fines piping, frame mounted exhauster fan with high efficiency dust collector fitted with screw conveyor for discharge of dust.

High pressure jet burner is capable of heating the aggregate to the required temperature without any unburnt fuel or carbon residue on the aggregate and it also reduces the moisture content of the aggregates to bare minimum. The drying and mixing device is also fitted with suitable type of thermometric instrument at proper places so as to indicate the temperature of exhaust gases, bitumen and mixture.
Fuel tank for dryer burner

Fuel tank for dryer burner

The dryer burner supplied with mini hot mix plant is compatible with multi fuels. There is a standard fuel tank supplied with the plant to store and supply the desired amount of fuel to the dryer burner. This tank also comes with its pumping station.

Venturi type wet dust collector pollution control device can be supplied with the plant as secondary pollution control device to keep the pollution control levels to minimum.
Bitumen tank with control cabin

Bitumen tank with control cabin

Bitumen storage tanks supplied with MDM 25 plant is of capacity 12 Tons and is mounted on a FULL chassis. The tank is fully insulated on all sides with glass wool in order to avoid heat loss and reduce fuel consumption of the burner.
Diesel compatible burner, bitumen pump is with with jacketed body, bitumen metering system is with variable speed motor and hot oil circulation motor are standard accessory with the bitumen tank. Bitumen tanks are available in various capacities as per the customer's requirement.
Lime / Mineral filler

Lime / Mineral filler

Provision for addition of dust or mineral to the mix material in the mixing zone of the dryer is there. It is provided with a rotary valve driven by AC/ DC motor. Filler material is conveyed to the drum through the drum through a pipe by suitable twin lobe compressor The input of minerals is adjacent to the bitumen line in the drying and mixing drum.
Lime filler is fixed with bitumen tank and cabin in a separate chassis.
Tilting type load out conveyor
Tilting type load out conveyor

Tilting type load out conveyor

The aggregate discharged from the drying drum is discharged and transferred to the truck by a heat resistant belt supported on an inclined load out conveyor equipped with GOB hopper. This GOB hopper is equipped with hydraulically operated cam shell gate to provide surge capacity when changing trucks and to control segregation in the hot mix.

Hydraulic Power Pack is provided as it helps in hydraulic opening and closing of the hopper gates. The storage capacity of GOB hopper is 0.5 tons.
