1. Cold Aggregate Feeder Unit
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.
2. Dryer & Mixing Unit
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.
This drum is divided into two zones viz.
- Heating + Drying Zone
- Mixing Zone
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.
3. Dryer Burner
Thermo - drum Burner
is the heart of the entire system hence its efficiency, ease of
serviceability etc. are most important factors.
Salient

cleaning is possible during running condition.
- Remote
controlled & fully automatic operation.
4. Asphalt (Bitumen) Tank
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.
Burners
are fitted with remote control system to detect flame failure and have
Electric spark ignition system.
The temperature is controlled through thermostatic control device to
heat bitumen in desired temperature range
Salient
Features
- Single stage
- Capacity to attend
Tank Temperature up to 160° C
- Able to use LDO/ FO/
diesel as fuel.
- Made In Italy (
BENTONE / ECOFLAME MAKE).
- Remote controlled
& fully automatic operation.
5.
Load Out Convyer
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.
6. Computerized
Control Panel With A.C. Cabin
Insulated Control Cabin Fitted With Air Conditioner.
Micro
Controller Based Control Panel With Printer And Computer Affording
Total Control Of The Plant From The Keyboard With The Relevant Software.
Salient
Features
-
The plant is
supplied with centralized Control Panel.
-
All controls,
including the motor control center circuit breakers, are provided in
the control panel.
-
The
control Panel comprises of the Automatic Burner Controls, Aggregate and
Asphalt Blending Controls, Motor Controls, Feeder Bin Controls and
Electric Switchgear.
-
All
the parameters like, temperature of bitumen-hot mix material-exhaust
gases and aggregate weight, asphalt percentage, hot mix material weight
etc. are displayed on the control panel.
-
It is equipped
with protections like Single Phasing, Overload, fuses, Sequence
Interlock etc.
-
Load wise data can
be printed on the printer provided in the panel.
