As 2007 more than 100 plants of capacity ranging from 30 to 120 TPH are in operation.
- DM-45 (Capacity 40-60 tones/hour)
- DM-50 (Capacity 60-90 tones/hour)
- DM-60 (Capacity 90-120 tones/hour)
FOUR BIN FEEDER
The Four Bin Feeder unit is having four bins and each bin is driven by individual A.C. Motors and gears for speed variable to flow of aggregate. All the four bins are having a screw gate, which is calibrated for adjustment to allow the opening / passage for materials to be dropped on conveyer belt. The sum of all the bins will comes on a second conveyer belt known as gathering belt, and the same will be transferred to oversize removal vibrating screen and will be transferred to Slinger conveyer.
The unit is single deck type vibrating screen removes oversize material and feeds the remaining material to charging conveyor. Separate size of screen can be provided for removing oversize material is form different kind of mix.
Slinger Conveyer conveying aggregate materials from four bin feeder to dryer drum unit..It is fitted with Electronic Load Cell continuous weighing System of Cold Aggregate Receiving from Four Bin Feeder.
DRYING AND MIXING UNIT
This unit of the drum mix asphalt plant is heart of the plant. As celled the aggregate is heated with automatic burner to require temperature and bitumen is added in the drum at suitable stage and bitumen is coated evenly to the aggregate in this drum. There are stages in the Drum like Preheating, Heating, Asphalt mixing Zone helps the aggregate and bitumen to heat and mix uniformly. The fins in the dryer unit are specially designed to get maximum heat efficiency that is to say minimum heat loss.
Dust Collector & Exhaust Unit : The dust collector unit is fitted at end of the Drum cell that is at the output and of the plant. It is having an efficient dust collecting system and fitted shutter with can be varied as required. An exhaust fan having sufficient capacity to ensure an effective airflow through the dryer and dust - collecting unit.
In the asphalt equipment, the High pressure jet burner with drying and mixing unit is capable of heating the aggregate to the required temperature without any UN burnt fuel or carbon residue on the aggregate and to reduce the moisture content of the aggregate to minimum. All Hot mix asphalt plants come with the unit which is also fitted with suitable type of thermometric instrument at proper places so as to indicate the temperature of exhaust gases, bitumen and mixture. For pressure Jet burner a suitable Fuel storage tank with fuel transfer pump is provided.
The low noise burner has sufficient capacity to cover the entire range of thermal energy required for drying the aggregates with various type of fuel in a hot mix plant. The combustion of the dryer burner satisfies the requirement of environmental regulations.
LOAD OUT CONVEYER
It is elevates the mix aggregate to such height that the mix material can be directly loaded in the dumper it is fitted with hydraulically operated hopper with helps the material to fall without segregation.
BITUMEN HEATING & STORAGE TANK
Storage tanks in our stationary and mobile hot mix asphalt plant are mounted on a sturdy chassis.
These storage tanks are cylindrical or U shaped. The tank is insulated with glass wool to avoid heat loss and reduce fuel consumption.
Automatic pressure Jet oil burner, bitumen pump with jacketed oil body, bitumen metering system with variable speed motor and hot oil circulation motor is provided.
Depending on the requirement of the customer, supplementary bitumen storage tanks can be provided.
COMPUTERISED CONTROL PANEL WITH DIGITAL DISPLAY
The Control Panel has in - feed master control. Aggregate flow measurement system, which controls asphalt flow, individual Aggregate flow from bins,
Providing Asphalt flow indicator, Automatic synchronization of aggregate with asphalt, Totalizer of aggregate and asphalt, To Printout record of all parameters for an instant verify of formula, Automatic Temperature control with indication, metering for Aggregate, Asphalt, Moisture and Motor Load.
It is fabricated from CRC sheet and processed with painting.
It is provided for control panel to see view and operate all equipments of plant. Control cabin is fabricated with M.S. structure and insulated by Thermocol & wood.
MINERAL FILLER UNIT
It is also fitted at the output end of the plant Filler unit in to lime / cement / dust feeding rotary pump with fitted AC motor drive and air blower quantity of filler material to be added in the mix.
Fuel tank is also supplied with the plant having capacity 2000 Ltr. up to 10,000 Ltr. As per require capacity of plant.
POLLUTION CONTROL DEVICES
VENTURI TYPE Wet dust collectors are highly efficient and are known to maintain required environmental standards in stationary or mobile hot mixers. The extreme turbulence leads to superb entrapping of dust laden exhaust gas.
Large size stainless steel nozzle provides a clog free operation to ensure optimum cleaning efficiency.
Can also fit it on hot mix plants. Also available Bag house filters customized for stationary and mobile hot mix plants.
HOT MIX STORAGE SILO
Kesar offers complete standard solution for safety storage of Asphalt.
Silos are supplied with standard safety controls.
The Silo is rigid easy to erect and transfer.
