25m3 filler tank 1000kg mixer capacity asphalt drum mix plant for
Max capacity: 240t/h (Working under rated condition)
Mixing evenness: meet the quality requirement of any asphalt
1. Cold Aggregate Supply System
Cold aggregate supply system adopts frequency speed regulation PLC control system for belt moving at proper speed flexibly.
Each aggregate ground hopper is equipped with feeding belt and audible and visual alarm device, as soon as actua aggregate conveying is below the
lower limit or suddenly being short of material, the device would
alarm immediately to remind the operator to treat with that
situation in time. The door of the cold feeder could be
appropriately adjusted to meet the requirement of the aggregate
2. Drying Cylinder
Drying drum rotates automatically driven by four frictions
wheels,which is equipped with spearate motor and reducer.Rotation
of dryer body provides sufficient heat exchange area for aggregate
After being conveyed into drying drum, aggregate goes into the
special designed lifting blade, which makes the material falling
uniformly like the “aggregate curtain”, so that the aggregate can
make sufficient heat exchange with the thermal energy produced by burner. In the flaming area,there are special thermal protection blades, which would ensure no
“aggregate curtain” in this area so that the flame would be sufficient burning, and form a protection layer between the blame and the
internal wall of the drying drum in order to reduce the heat loss.
Italy EBICO oil burner imported with original packing, which has
high burning efficiency, diesel, diesel/masut/ /natural gas as fuel
Burner control system provides function of remote automatic
ignition and monitoring working condition. It is set with failure
automatic flame out, failure automatic diagnosis and failure inspection instruction device which make the whole
combustion system works safely and efficiently.
4. Dust Collection System
Two level dust collection system (volute casing collector + bag
house collector), with high and low temperature protection device
for the system security.
Bag house collector using USA Dupont NEMEX bags, heat resisting and
Environmental friendly, emission concentration is less than
The bag of the bag house filter adopts high temperature resistant
material, which can withstand 220°C high temperature. All the bags
inlet are equipped with spring buckle, combing with the special bag
support frame, which ensure quick and reliable fixing work of bags.
5, Mixing system,
Twin shaft compulsory mixer,horizontalshafe vortex type, driven by
double geared motor reducers via equal gear wheels. The special
mixer design is featured by double paddle arm pattern with powerful
and intensive stirring mode, at low rotation speed and large
capacity, effectively avoids segregation and secondary gradation
changes during mixing, ensuring stable and ideal mixing quality.Mixer shafts has seals which achieves zero leakage.
Based on types of asphalt batching plant, two discharge methods are applied: discharging finished bitumen
mixture into trolley which goes to finished product silo for
discharging the asphalt finished product directly into the trucks
from the bottom of the mixing tower.
