The hoppers have been properly designed with slopes, allowing a constant discharge without bridge forming. The first bin meant for the small size aggregate or dust is fitted with vibratory motor to ensure the free flow. Each hopper is equipped with an adjustable opening door that determines the discharge quantity for the materials capacity in outlet, as a function of specific weight of materials.

The material is drawn out from the hoppers by means of extracting conveyor driven by a preset-able adjustable variable drive motor, coupled with worm gear boxes, that enables to increase or decrease the material output as per the job mix formula requirements. It is also possible to increase or decrease the total capacity without varying the preset settings by means of master control.

The vibratory screen is assembled at the end of cold aggregate feeder for removal of oversized materials.

The Dryer unit is long rotating cylindrical drum. It is mounted on sturdy and robust steel structure. The whole structure is having adjustable height legs to give proper degree to the unit for accurate results.

The electronic two-stage high-pressure jet burner is mounted on the chassis on the input side.

The rotation of Drum is through heavy-duty gearbox, coupled with motor through suitable coupling. The Drum is also supported by 4 Nos. of Trunnions rollers running on heavy-duty bearings.

The thermo-drum is completely insulated with ceramic glass wool and covered with Stainless Steel sheet to prevent the heat losses and to save fuel as well as the life of the drum.Before the mixing zone a suitable flame guard is provided to restrict the burner flame to reach up to the mixing zone.

The special 8 mm thick 'J' type flights + 'W' type comb flights have been bolted in the both the zones in the zigzag / straight pattern for best mixing.

The dust collecting system mounted on same chassis allows optimum efficiency in accordance with the present ecological regulations.

The dryer and mixing drum is provided with sweep discharge chute on the side of the mixer with replaceable type chute liners and it will discharge the material directly on the load out conveyor.

Thermo - drum Burner is the heart of the entire system hence its efficiency, ease of serviceability etc. are most important factors.

Salient Features :

• Two stage High & low
• Capacity to reduce the moisture up to 0.5% and achieve 180 Deg Celsius for aggregate.
• Able to use LDO/ FO/ diesel as fuel.
• Nozzle cleaning is possible during running condition.
• Remote controlled & fully automatic operation.

Fully insulated double walled tank is equipped with separate high-pressure electronic burner for heating the Asphalt and control unit capable of metering and spraying required quantity of bitumen at specified temperature.

Salient Features :

• External insulation with ceramic wool and covered with suitable thick sheet
• Tested tube nest for diathermic oil circulation.
• Thermic duct, Manhole, lifting hooks, Breather pipe.
• Electronic High-pressure Jet burner.
• Heavy duty jacketed Asphalt pump.
• Thermometers.

Mixed hot material taken out from mixer drum is carried by inclined hot conveyor belt & discharged into the Tipper/Truck through automatic Hydraulic surge storage hopper.

The surge storage hopper of approximately 350 to 1000 kgs is provided at the discharge end of the conveyor.

The surge storage hopper is hydraulically actuated, for opening and closing hopper door and scrapper plate to scrape out the mixed material sticking to the conveyor.
