Fully Automatic Stationery Asphalt Drum Mix Plant In All Ranges :
Enlarge
Land Area Required For Asphalt Drum Mix Plant : 50 Mtrs. X 50 Mtrs. ( Approx.) OR 164 Ft. X 164 Ft. ( Approx.)
Salient Features :
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.
This drum is divided into two zones viz.
1. HEATING + DRYING ZONE2. 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.
Thermo - drum Burner is the heart of the entire system hence its efficiency, ease of serviceability etc. are most important factors.
Layout
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.
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
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.
