Mounted Bitumen Pressure
ASPHALT DISTRIBUTOR: Mounted Bitumen Pressure
Universal bitumen sprayer with multi nozzle spray bar for spraying the bitumen on the surface before laying the hotmix material.
Bitumen Sprayer depending on the tank capacity is suitable to be mounted on trucks or trolley (chassis of vehicles). The bitumen is stored in the tank is heated by the burner and the molten bitumen in the tank is pumped by the pumping station to deliver it to the spray bar. The spray bar fitted with the nozzles sprays the bitumen in required quantity in combination of the vehicle speed across the width of the surface. Major components: Asphalt Tank, Heating system, Circulating & pumping system, Spray Bar, Hand Sprayer, Controls & Guages Mounted Bitumen Pressure
Asphalt tank vary in size from 4000 ltrs. to 10,000 ltrs. The tank is insulated by cera wool to prevent the asphalt from cooling too quickly. Two or three baffle plates are provided inside tank to stabilize the load while in motion. U-shaped flue tube covers the length & breadth of the tank providing enough surface area for maximum heat transfer. The tank is equipped with thermocouple. Manhole is provided at the top of the tank for filling the asphalt and visual inspection purpose. Heating system
Diesel fired burner is mounted at the front side of the tank and positioned such that the flame is directed into the flue tubes that pass through the tank.
Circulating & pumping system
Sprayer is equipped with positive displacement type hot oil jacketed asphalt pump, driven by diesel engine, to spray asphalt under pressure onto the roadway. The pump also serves to provide a circulation system. The asphalt is required to be circulated in the asphalt lines as well as spray bar for spraying and also for cleaning to prevent the asphalt setting in the lines and that may clog the same and spraying nozzles. The pump can be used to fill the sprayer tank as well as for transferring the asphalt from one tank to another. Filters are provided between the tank and spray bar to prevent particles of burned asphalt or impurities from entering the spray bar and clogging the spray nozzles. Spray Bar
The spray bar and spray nozzles regulates the amount of asphalt sprayed on the roadway and regulate the spray pattern. The spray bar is foldable with 4.5 mtrs. maximum spraying width and comprises of a series of spray nozzles evenly spaced along the bar. It contains a return line for continuous circulation of asphalt through the bar. Spray bar is equipped with pneumatically operated gate for spraying nozzles. The spray nozzles manufactured from brass material are designed to spray a fan shaped pattern.
Sprayer is equipped with a hand sprayer for use in narrow, ir-regular shaped area that are inaccessible to the spray bar. The hand spray bar is equipped with shut off valve.
Control and Gauges:
To deliver a uniform and precise amount of asphalt at desired temperature and rate onto the roadway, the distributor is equipped with mechanical valve, pressure guage, thermocouple etc.
