Description
RD**5 Asphalt Mixing
PlantÂ
1. Cold aggregate supply system
Frequency
conversion timing with credible capability; modularized design will
be convenient for transport.
2. Tilted belt feeding
system
Automatically flow middle filter with no
vibration will prevent the oversized material entering the drying
drum; reduce the heat loss. Avoid jam in the hot aggregate elevator
and the vibrating screen.
3. Drying drum
Outside the drying drum is covered with a *0mm heat preservation
structure, and inside the drying drum fixing up blades used for
lifting aggregate, which can reduce heat loss and ensure the
highest thermal efficiency.
The drying drum is driven by four friction wheels, freely link,
smoothly and evenly drive.
4. Burning system
The burner is equipped with gas ignition device, with high ignition
success rate. It will ensure that first-rank burning effect and
drying efficiency.
Burning system uses automatic temperature-control function. It will
ensure the best burning effect and drying efficiency.
The burning system can use diesel (heavy oil, gas, coal) as the
fuel, through the accurate automatic control to reduce production
cost.
5. Filler supply system
The outlet of
screw conveyer installs butterfly valve to control wallop. Filler
temporarily storage silo using high-press air to explode the
agglomeration.
6. Pneumatic control system
Pneumatic system uses Germany FESTO air cylinder and
electromagnetic valve, with reliable performance and long service
life.
7. Asphalt supply system
Asphalt will be heated by the circle hot wind pipe. The tank will
be placed under the ground to be convenient for discharging
asphalt.
8. Electric control system
The control room copy container structure, the walls, door and
windows are made of colorized steel plate. Pleasing shape, good
seal; easy to hoist and transport.
Box type control cabinet, main electric parts are SIMENS ,
Schneider, ABB etc. global famous brand, which has interlock and
two-grade protection; the big motor adopt reasonable
voltage-reducing start; urgent manual operation device, digital
indicator for filler balance, aggregate balance and asphalt
balance, cold aggregate digital transducer, teperature indicator
and flow indicator for main components;
Japan OMONLON colorized touch screen and PLC controller, can
operate by automatically, Semi-automatically and manual
control; it could realize many languages switching on line; inside
control room will reserve a joint position for printer; asphalt
weighing will take two steps and detect asphalt &aggregate
ratio real-time for each batch; Control is advanced, capability is
credible, operation is convenient and obvious.
