DRYING & MIXING UNIT |
|
The Dryer unit is long rotating cylindrical drum. It is mounted on sturdy and robust steel structure is having adjustable height legs to give proper degree to the unit for accurate results.
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. This drum is divided into two Zones viz.
- HEATING DRYING ZONE
- MIXING ZONE
The thermo-drum is completely insulated with ceramic glass wool and coverd with Stainless Steel sheet to prevent the losses and to save fuel as well as the life of the drum.
Before the mixing Zone suitable flame guard is provided to restrict the burner flame to reach up to the mixing Zone.The special 8mm thick ‘J’ type flight +’W’ type comb flights have been bolted in the zones in the Zigzag/strait pattern for best mixing.
DRYER BURNER
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.

FOUR BIN FEEDER UNIT
|
|
The hopper 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 conveyer driven by a preset-able adjustable variable drive motor, coupled with worm gear boxes, that enables to increase or decrease the material out put 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.

ASPHALT TANK BURNER
|
Asphalt burners are fitted with remote control system to detect flame failure and have Electric spark ignition system.
The temperature is controlled trough thermostatic control device to heat bitumen in desired temperature range.
|
|
|
FEATURES OF ASPHALT TANK BURNER :
- Single stage
- Capacity to anteed Tank Temperature up to 160° C
- Able to use LDO/FO/ diesel as fuel.

|
LOAD OUT HOT MIX MATERIAL CONVERYOR |
|
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.
|
MINERAL FILLER UNIT |
The piping is provided up to-coating zone in the thermo-drum.
The system is powered by a variable speed Motor coupled with gearbox to rotary valve and also synchronized with aggregates and bitumen.
The feeding of filler(lime/cement) is pneumatic by means of air blower. |
