Main Structures of the Asphalt Mixing Plant
 |
1.Cold aggregate supply system Components： storage bins and belt feeder , aggregate belt conveyer. Features: The feeding belts are driven by variable frequency electric motors, which feature reliable performance. The cold aggregate feed bin features modular design for easy transportation. We have 3,4,5 storage bins for your choice. |
 |
2. Tilted Charging Conveyor Belt Assembly |
 |
3.Drying drum The drum lined with a 50mm thick insulation (rock wool).Aggregate lifting flights that assist the heat exchange between aggregates and flame are installed inside the dryer drum, which enables the drum dryer to reach maximum heating efficiency.Four friction rollers for smooth drive and evenly distributed forces. |
 |
4.Burning system For the burner , we have fuel burner (light oil, for both light and heavy oil), coal burner or for both fuel and gas use burner, pipelines,oil tank |
 |
5.Hot aggregate elevator Elevated by Single row of chain，special structure for outlet will reduce the abrasion and noises. |
 |
6.Dust removal system 1.bag house 2. gravity separator (snail shell shaped) 3.cyclone separator 4.wet scrubber |
 |
7. Mixing building |
 |
8.Filler supply system Components： Filler elevator, Filler temporary storage bin, spiral conveyor. The outlet of the screw conveyor is installed with a butterfly valve to control the wallop. The filler interim silo is equipped with a pneumatic arching break unit. |
 |
9. Pneumatic control system Components： air compressor, cylinders, valves and air pipe manifold. Reliable FESTO air cylinders and electromagnetic valves are used. |
 |
10.Bitumen supply system Components： bitumen discharge vessel,bitumen tank, heat conducting oil boiler, light oil burner, pipe manifolds, pumps and valves. Features: 1.Reasonable bitumen pipe arrangement with insulation to reduce heat loss 2. Heat conducting oil boiler with automatic control system for independent operation and control. 3.Bitumen tanks with level and temperature indicators |
 |
11. Electric control system 1) control room:Container pattern structure. 2).Box type control cabinet, main electric parts are SIMENS , Schneider, ABB etc. global famous brand.Functions of interlock and secondary protection.Start of large power electric motors at reasonably low voltage. The operation board configured with manual controlled urgent operation device, digital displays of aggregate scales, filler scales and bitumen scale, digital converters of cold aggregates, temperature displays of key positions and electric current displays of critical components |
 |
12.Side Placed Hot Mix Asphalt Silo 1.The silo is divided into three sections: upper, middle and lower, and two compartments: left and right, for easy transportation and erection. 2.Silo is insulated. 3.Anti-segregation device is configured inside the silo. 4.The bottom of silo and the discharge floodgate are electrically heated. |
