With the continuous process of urbanization, the city construction waste generation is also growing rapidly. While people are engoying the urban civilization, they are also sufferred by municipal waste, including construction which waste takes up a large proportion, and accounts for 30%~40% of the total garbage. According to some informations, there is a rough statistics to the construction materials waste of the brick-concrete structure, frame construction revealing that, In the construction process of 10,000 square meters, only construction will produce 500 to 600 tons residues. It will reach hundreds of million Tons if including architectural ornament, removal and rebuilding, and construction materials. So how to deal with and reuse of an increasing number of construction waste, has become an important topic by the government departments at all levels and construction waste disposal unit.

Lots of construction waste can be re-used as renewable recources after sorting, removing or crushing. Eg: Scrap steel, scrap iron, scrap wire and various of scrap steel accessories can be re-processing into a variety of steel products after sorting, collecting, and re-melted down. Bamboo wood waste can be used in making of man-made timber. Brick, stone, concrete and other waste can replace sand after crushing, and used for masonry mortar, plaster mortar, hit the concrete layer, etc. and also used to make brick, road brick, lattice brick and other building materials. Therefore, we must insist on comprehensive utilization in construction waste disposal. In the process of urbanization, rubbish was once the burden of urban development, and many cities in the world once were sieged by rubbish. But today, rubbish is considered to be the most potential for development, inexhaustible "urban mines", and "misplaced resources." This is in-depth understanding to the rubbish, and also an essential requirement for urban development.

With the emphasis on environmental issues gradually, energy saving, environmental protection has become a theme of national development, and has begun to provide industrial development opportunities of garbage disposal. the world rubbish increment speed is 8.42% for per year. Renewable resources has become a new starting of resource recycling, and also an important component of the recycling economy. What's more, it is not only solved the shortage of resources, but also reduced junk emissions during the recycling process to the waste resources and waste material, which can be described as "double benefit." Governments leaderships have begun to pay great attentions to the landfill construction, and increased investment in it, so we can predict that there is a bright future in waste disposal industry.

So how to disposal with the construction waste? Yifan company adopts crusher to deal with it, according to integrated design to the crusher, Yifan company produced the Mobile Crushing Plant which can make waste profitable. Most construction waste is solid waste, generally generated during the construction, maintenance of old buildings, or demolishing process. Different structural types of construction waste generated various of components, but the basic components are the same, they are mainly composed of the soil, scattered mortar, concrete, reinforced concrete under the trailer coupling, metal, bamboo wood, wastes decoration, all kinds of packaging materials and other waste, etc. what's more, the disused building concrete and bricks can produce aggregate, which can produce corresponding strength grade concrete, mortar, building materials that can produce block, wallboard, floor brick and so on. Reuse waste brick produce aggregate that can be used in the production of renewable bricks, blocks, wallboard, floor brick and other building material products, which can realize construction waste reduction, recycling, saving natural resources, protecting the ecological environment, and have a high economic value.

Becasue of construction waste are piled on a concentrated, relatively limited space, traffic is not very convenient, and mobile crushing plant is the combination of crushing and screening, so it can multiple stage crush to a variety of chunk materials. What’s more, Mobile Crushing and screening plant is flexible, convenient and strong in mobility, so it can save a large construction capital and relocation. Raw materials can be broken at the locale without being transported again, and also can be moved with the promotional exploitation of the raw material, which saves a large number of transportation costs. The Mobile Crushing Plant has flexible deployment, the design can be modified according to actual scene, so it is suitable to the construction waste crushing.
