Nowadays,with the transformation of cities, a large number of construction waste has been generated, which leads to the destruction of the ecological balance. The disposal of construction waste will increase our construction costs and waste a lot of manpower. Building waste residue has good physical and chemical stability, and its performance is better than that of clay, silt, sand and limestone. These properties determine that construction waste crusher is a good machine for construction waste disposal, which can be applied in engineering construction to turn these waste materials into treasure. The appearance of mobile crusher not only solves the land pollution problems in cities, but also achieves the beneficial development. The design philosophy of mobile crusher is based on the actual needs of customers, which takes removing the obstacles of crushing sites, environment and complex configuration as the primary solutions. construction waste crusher is the complete set of mobile crushing and screening equipment placed in one or several trailers, which is composed of raw material bin, vibrating feeder, multilayer vibrating screen, medium crushing equipment, fine crushing equipment, mobile belt conveyor, sand washing machine, electrical control system, etc. Mobile crushing plant is the integration of feeding, crushing and conveying. With the optimization of the production process, it has excellent crushing performance in rock crushing, aggregate production and open-pit mining. It can form a powerful crushing flow line through a combination of different models to complete more operations than demand, which has economic operation cost, stable and reliable operation and high production efficiency. Mobile crushing plant mainly conducts the construction waste crushing and screening after assembling the jaw crusher, impact crusher, vertical shaft impact crusher, hydraulic cone crusher, vibrating screen, feeder and a variety of special equipment. Through the optimization and strengthening design, it has higher strength, firm structure, reliable performance, good stability, less transportation costs, flexible combination, strong adaptability and convenient repair. The recycled materials is widely used in baking free brick, road infrastructure, construction and other industries to provide a new development ideas for the virtuous cycle of city construction field.
