160KW draught fan QLB-3000 model hot mix aspahlt machinery with bag dust filtering
Advantage of Xitogn forced batching type asphalt mixing plant
1,Cold Aggregate Feeding Bin
- Feeding process is controlled by frequency converter, under automatic control mode, to make feeding stable,smooth and continuous.
- equipped with alarming device for material shortage
- High wear resistance seamless belt has longer service life
2, Drying Drum & Burning System
- Comparing to conventional design, exclusive design of material blade inside drum body could improve heating efficiency by 30% or more.
- Body and blade material adopt 20G boiler iron for longer service life
- 50mm thickness heat insulation layer bring better heat insulation effect
- Butterfly shaped elastic connection plate avoids elastic cracking
- Italy EBICO oil/gas/coal powder burner has high combustion efficiency, which is saving
energy and with low emission.
Mixing Tower
- Improved vibration and optimized amplitude largely reduce the impact on the screen and plugging rate
- 36 square meter screening area takes the lead in this class
- Adopt long arms and short shaft, its superficial structure, more compact
- Large sliding gate structure, discharge asphalt mixture speedy
- Mixing blade and scale board adopt wear-resistant alloy iron, long service life
- Bidirectional mixing blades, mix in 3D spaces, high mixing efficiency
Bitumen Storage & Heating System
- Electric/diesel/gas/coal powered heating type as optional for convenience of users
- QINGTIAN bitumen gear pump, long service life and low failure rate
- Integrated modular design, easy to transport
Dust Collecting System
- Gravity primary dust collector collecting and recycling bigger particle, saving consumption
- Bag house secondary dust collector control emission be lower than 20mg/Nm3, eco-friendly
- USA Dopont NOMEX material filter bags, high temperature resistance and long service life
- Smart control of pulse dust removal system, removing dust clearly
- High temperature alarming and automatic cold air value unit, ensure safety of bags
- Dust humidification mixing machine to avoid dust flying
Control System
- Adopt Usa METTLER TELEDO weighing modular accurate weighing
- Adopt Germany FESTO cylinder & magnetic valve, long service life and low failure rate
- Germany Schneider electrical element, working stably
- Japan Mitsubishi PLC and touch screen, with multi-language display and intelligent human-computer interaction interface, easy operation and control
