DRYING & 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 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 into two zones viz.

HEATING + DRYING ZONE + MIXING ZONE

The thermo -drum is completely insulated with ceramik 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 flight+`W` type comb flight have been bolted in the both the zones in the zigzag / straight 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.

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

FOUR BIN 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.

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 through thermostatic control device to heat bitumen in desired temperature range.

FEATURES OF ASPHALT TANK BURNER

• single stage
• Capacity to attend Tank Temperature up to 160 C
• Able to use LDO/FO/ diesel as fuel.
• Remote controlled & fully automatic operation.

POLLUTION CONTROL UNIT

High efficiency wet dust collector controls the dust & maintains the required environment standard in specified areas.

STORAGE SILO

Storage silo is full insulated aggregate hopper its capacity 5 ton to 25 ton or on requirement  

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 is provided at the discharge end of the conveyor. The surge storage silo is hydraulically actuated, for opening and closing hopper door automatic & manual and scrapper plate to scrape out the mixed material sticking to the conveyor.

CONTROL PANEL BOARD

Insulated Control Cabin Fitted With Air Conditioner And Micro Controller Based Control Panel With Printer And Computer Affording Total Control Of The Plant From The Keyboard With The Relevant Software.

FEATURES :

• The control panel comprises of the Automatic Burner Controls, Aggregate and Asphalt Blending Controls, Motor Controls, Feeder Bin controls and Electric Switchgear.
• The plant is supplied with centralized Control Panel.
• 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.
• All controls, including the motor control center circuit breakers, are provided in the control panel.
• Load Wise data can be printed on the printer provided in the panel.
