For ecological and economic reasons,Recycling technology has become an inevitable trend.。Because the recycling of asphalt and stone in the recycled old materials can save raw materials.,It also avoids the trouble of disposing of old materials.。
In the following,We will describe in detail the two kinds of Anmai.RAPAdd a system。
RAH50 Regeneration drum
Addition technique through an intermediate ring
Perform cost optimization and recovery heating
The middle re adding mode is that that recycle material is added to a drying roller through an annular feeding device,Raw material and recycled material are heated in the same drum。
From a cost perspective,This technology is very attractive.。AMAI relies on a very gentle heating process.,The asphalt contained in the recycled material is recycled in an optimal manner。This is achieved by adding bitumen in the middle of the raw meal drying drum。The precious bitumen is mixed with the virgin mix at moderate temperatures,It will not age due to overheating of the stone.。Through a special internal device.,The mixture of the recovered material and the virgin material is gently and gradually heated to the desired temperature。
Up to 50 can be achieved in this way%The proportion of recovery and addition。
AnmaiRAHTechnical advantages of 50
Mild heating maintains the quality of the asphalt;
High throughput through bottom discharge;
Compared to other heating technologies,Lower investment cost;
Adopts countercurrent drying technology,More efficient。
RAH100 regenerating drum
Highest recovery addition ratio,
Meet the most stringent emission requirements
Anmai Development and LaunchRAHThe 100 recycling addition technology is designed to meet the highest regeneration requirements。Since the first set of equipment was put into use in 2005, ,The product has been improved in many details.。Nowadays,It can be said that all the goals have been achieved.,Maintenance is kept to a minimum.。
At present,There are more than 80 sets of AnmaiRAH100 systems operate worldwide,They were installed in a new facility in Anmai.、Above the modified Anmai or other brand mixing station。
AnmaiRAH100 technical advantages
Thanks to air heating technology(The material is heated with hot air),Asphalt quality is maintained;
The recycled material can be heated to 160º C,Overheating of the raw meal is no longer required;
Air is circulated through the scrubber,Lowest maintenance and upkeep costs;
There is a start/Stop operating the design,The minimum yield is 40 t。
