Construction waste recycling processing
1.Construction waste recycled background material
With the development of the economic in our country and the rapid step in our Rural and urban construction, the construction waste is increasing as the time goes, and its amount also goes up year after year. The total amount of construction waste takes up 30% to 40% in our city waste ,so the peak of producing construction waste has come here. Each year the production of solid construction waste is more than 800 million tons, and 95% of them can be recycled. Currently, most of the country's construction waste is moved to the countryside in the open air or is landfilled outside without any special treatment, which not only consumes a lot of land resources, and leads to the serious pollution to the environment. What’s worse, there is almost no room to be buried or piled up today and “garbage and" has become a common phenomenon. Therefore, in order to devote to the sustainable development of society, it is necessary to solve the problem of the construction waste recycling.
2. Construction waste treatment processing technics and equipment
After a long-term research, Zhengzhou Dingsheng Engineering Technology Co., LTD developed crushing and screening equipment, which will process construction waste into recycled concrete aggregate, new type wall raw materials, the road base course filling accessories, and other solutions.
Construction waste is usually processed with two types of the mobile and Stationary Crushing Plant. Inplace regeneration ----employ the portable equipment to deal with the construction waste on the scene. Plant regeneration—employ the fixed equipment to deal with the construction waste in the plant.
3.The typical use of the construction waste recycled materials
0 – 2.5 mm recycled materials Used as the main raw material of wall with mortar ;or replace river sand.
0 – 4.5 mm recycled materials Used as the main raw material of bricklaying mortar.
2.5/4.5 – 10 mm recycled materials Used as the main raw material for brick making.
10 – 32 mm recycled materials Used for road construction raw material.
>32 mm recycled materials back into the crusher; or for rock embankment.
4. The characteristics of the construction waste processing equipment
Integrated mobile crushing plant
The installation of the integrated mobile crushing plant eliminates the complicated basic facility installation procedure in multifarious site, and reduces the expense of materials and time. The reasonable and compact spatial distribution of the equipment improves the flexibility of the placing.
