Dregs as urban infrastructure construction、The subsidiary product of urban residential building development，In the past, the dynamic balance has been maintained through the adjustment of the location environment of the city.。But，This balance has been broken after the city entered the transition period of rapid social and economic development.。With the development of urbanization in China,、Rapid construction of underground space，The amount of dregs is increasing day by day.。The transportation and disposal of dregs has become a difficult and hot spot in urban management.。

How to deal with dregs scientifically，Thoroughly solve the problem of environmental damage caused by dregs、Contaminate the water supply、Invasion of land、Many social problems such as city appearance are affected.，It has become an important issue we are facing.。Nanfang Road Machinery has entered the field of construction waste resource treatment since 2010.，Combining with its own industrial advantages, it continuously deepens the connotation of the overall solution of the whole industrial chain of construction waste recycling.。In 2014, the recycling of construction waste resources was extended to the field of water washing.，Put forwardHigh-quality washing solution for solid waste residue raw material。

△Nanfang Road Machine Washing Solution

Nanfang Road Machine Washing Solution，Sand and stone simultaneous washing process is adopted，It can be from the construction dregs.、Mine tailings、Construction waste recycled materials、River dredging、Sandbag soil、Recovering high-quality sand and stone aggregate from raw materials such as pebbles and the like，AndRefining and grading the sand and stone with complex gradation，Maximum recovery 75μmAbove fine sand，Zero waste of fine sand is basically realized.，Effectively control the water content of finished sand，Further improve the quality and added value of finished products，It is conducive to alleviating the situation that natural sand and gravel aggregates are gradually exhausted and production capacity is tight.，Create better economic value and environmental benefits。
