Main UnitMore Info
The key to high quality hot mix and continuous operation
Vibrating screen – high accuracy screening
Hot Bin – extends productivity of asphalt plant
Mixer – speedy and thorough mixing
Screen
- Powerful vibration generator
- Wide amplitude
- High vibrating frequency
- Large screening area
⇒High screening efficiency and accuracy
Hot Bin
- Number and volume of hot bins can be increased upon request of customer (optional).
- Continuous heating and mixing time can be extended by increasing the hot bin's storage capacity
Mixer
- Powerful and dynamic flow by twin-shaft pugmill mixer
- Optimal mixing life zone
- Speedy mixing
- High quality homogenous hot mix by circulation flow and double spiral flow
Aggregate supply unitMore Info
Feeder – Supply the optimal amount of aggregates to dryer
For the production of high-quality asphalt mixture, uniform and exact feeding of cold aggregates to the dryer is important.
In order to maintain a smooth feeding operation, the aggregates must be strictly segregated into particle sizes and stored in hoppers accordingly. Especially fine aggregates must be stored under cover so as to maintain a minimum and constant water content level.
Registering the supply capacity into the operation panel by appropriate calibration ensures that just the right amount of aggregate is automatically fed in according to the combination of each mix.
Combustion unitMore Info
Gas burner/Oil burner/Gas & Oil dual burner to choose from
High efficiency heat pack dryer – easy maintenance and improved performance
NTB Burner (Oil Burner)
For Higher Combustion Performance
NTB burner is a compact design, power-saving, and low-noise burner which reduces fuel consumption by its enhanced combustion performance.
It achieves an air ratio of 1:1 at maximum combustion with a wide combustible range (Max.1:5) and its optimal air-fuel mixture formation enables stable combustion.
NTBG Burner (Gas Burner)
High Combustion Performance & Environment-friendly
T-LEX Burner achieves an air ratio of 1.2 at maximum combustion with a wider combustible range compared to the conventional type and its optimal air-fuel mixture formation realizes stable combustion.
Low emission of nox (less than 18ppm)
40% reduction compared to conventional products
Low noise level
Newly designed high performance silencer reduces noise level by 5-10 d(A)
Conventional Type
- Zero emissions of SOx
- Reduced CO2 emissions
New Type
- Low NOx
- Low Air Ratio
- Enlarged combustion range
NTGO Burner (Gas & Oil Burner)
Hybrid Gas & Oil Burner
《Low environmental load ＋ Instantaneously accommodates changes in the market》
Characteristics of Oil burner
- Low air-ratio combustion
- Large combustion
- Low noise level
- Space saving
- Simple control & Safe operation
Characteristics of Gas burner
- Low NOx& CO2 emissions
- Low noise
- Zero SOx emissions
- Low environmental load
Gas & Oil Burner
- Flexible response to changing fuel price and plant conditions
- Easy switching between gas and oil
Heat Pack Dryer
- High Heat Efficiency
- Cost saving
- Low fuel consumption
- Low-noise,
- Easy maintenance
Compared to the conventional type, more segmentalized and uniform vailing improves heat transfer efficiency. The durability of the dryer is greatly improved by the reduction of radiating heat. The gear-less friction drive allows low noise operation and simple maintenance.

Flight
Dust collectorMore Info
Bag filter type or wet spray type & cyclone dust collector to choose from
Dry Dust Collector - BOND Type
- BOND (bag filter on dryer) structure
- Space saving
- Heat radiation from dryer retains optimal temperature at the bag house to prevent water condensation in the dust hopper unit
- Bag house shelters dryer from rain water and lengthens service life of dryer
- Detached dry cyclone (primary dust collector) and bag house (secondary dust collector) is combined
- Reduced heat radiation by a shortened smoke-way, exhaust gas enters the bag house at optimum temperature
- Hybrid structure reduces radiation area by 30%
- Speed of dust passing through filter cloth is reduced by 25% due to improved combustion efficiency
Wet Dust Collector
- An alternative, lower cost dust collector system
- Water is sprayed onto the exhaust gas and then evaporated
- Water vapor containing dust particles condenses and eventually flows out to the water tank
Asphalt Supply SystemMore Info
Electrical heating MDC tank or Hot-oil heating tank – adaptable to plant site condition
- Supplies asphalt from storage tank to mixer
- Accurate weighing and feeding to produce high quality hot mix
- Steady supply of homogeneous asphalt at uniform temperature
- (Optional) asphalt kettle for regions where only drummed asphalt is available
Electrical Heating
- Environmentally friendly
- Reduced heat dissipation
- Low installation cost
- Easy maintenance
- High safety standard
Hot-Oil Heating
- Fully automatic burner heats up oil to present temperature (around 180℃-210℃)
- Hot-oil circulating pump keeps heated oil circulating to maintain the asphalt tank, asphalt scale, spray device and pipe lines at preset temperature
- Hot oil heater control panel consists of temperature switch, pressure switch, oil tank level switch, 2-point temperature controller, and an alarm device
