Hot mix asphalt plant for sale is an advanced equipment, which can turn dead asphalt into new asphalt mixture. Dead bitumen will be smashed together, then it will be mixed with other materials in a certain proportion according to the quality requirements at different levels. Then the dead asphalt becomes reborn asphalt concrete, and used for road pavement, which can reduce your cost and realize materials reuses.
Application:
Mainly, there are two ways to regenerate asphalt, and they are site regeneration or plant mixing regeneration. Hot mix plant is quite suitable for plant mixing regeneration. After screening, heating, the dead bitumen will be put into the mixing drum in a certain proportion. Then it will be mixed with the original materials, and high-quality asphalt mixture forms.
And plant mixing regeneration has the advantages of low investment, low risk and quick return. The customers can only purchase matched asphalt regeneration equipment if they already buy a asphalt plant, which can avoid repeated investment and reduce purchasing cost.
Features and Advantages
- Dead asphalt can make 20% to 60% original materials in one hot mix plant for sale, which has a high materials utilization and economic benefit.
- It can control the regenerating asphalt quality very well. With considering the dead asphalt aging degree, water content and other parameters, proper addictive and regeneration process will be chosen, which can ensures the asphalt mixture quality in a great degree.
- With regenerating asphalt mixture, the elevation of the newly paved road will not change.
- With matched burner, dust collector and drying drum, the blue smoke produced during the heating process can be carried out combustion treatment again, which can can reduce the gas pollution.
Main Components
Mainly, hot mix asphalt batching plant consists of materials cooling system, feeder, feeding belt conveyor, heating system and burner, regenerating materials hoister, heat regenerating materials measuring bucket, dust removal system, control system and other part.
Material Cooling system
It consists of two separated material cooling and anti-screening net at the top of bin and vibrator in bin wall. Given that dead asphalt has a poor fluidity, this system is equipped with special-designed arch broken device, which can ensure the smooth transportation.
Feeder
Feed quantity can be controlled by frequency control device and opening degree of hopper door. With no materials inspection device and alarm device, they can notify materials feeding by signal transmitting and warning lights.
Feeding Belt Conveyor
It is equipped with wiper and emergency button. Besides, in order to avoid oversized recycled materials into the equipment, it is equipped with materials vibrating screen, which can remove useless materials in time.
Heating System and Burner
Heating system adopts downstream heating method, which can not only make full use of heat energy, but also ensures that the regenerated materials will not stick to the inner wall of the roller. Besides, strict exhaust temperature monitoring has be adopted to prevent the burning and aging of the asphalt on aggregates. As for the burner, it adopts compressed air atomization and combustion flame. In addition, it is equipped with heavy soil reheating system, temperature control system for regenerating materials and infrared thermometer, which ensures the better temperature control.
Regenerating Materials Hoister and Heat Regenerating Materials Measuring Bucket
Regenerating materials hoister adopts wear ring chain bucket elevator, which has anti reverse non-return device. Heat regenerating materials measuring bucket adopts sensor to control the weighing. Besides, the runner is heated and insulated by heat conducing oil, which can ensure the smooth circulation of the recycled materials.
Dust Removal System
Dust removal system adopts special-designed induced draft fan, which can effectively prevent the adhesion of the oil fume and fan blades. Besides, the blue smoke produced by thermal regenerating drying drum will be burned again in the main drying drum rather than being released into air directly, which can totally eliminate harm gas.
Control System
The control system adopts button free operating system, which can realize fully automatic operation and manual operation.
