The resource utilization of construction waste can effectively reduce the amount of stacking. Usually, the disposal of construction waste is mostly by means of accumulation, landfill, etc., which occupies a large amount of land resources, and it is easy to generate floating dust in the process of transportation and storage, causing certain pollution to the atmospheric environment. In this regard, Sanya City proposes that by the end of 2022, the discharge of construction waste (excluding engineering slag and engineering mud) at construction sites shall not be higher than 450 tons per 10,000 square meters, and the construction waste at prefabricated construction sites (excluding engineering slag) shall not exceed 450 tons. The emission of soil and engineering mud) shall not be higher than 350 tons per 10,000 square meters, the effective disposal rate of construction waste in the city shall reach 80%, and the utilization rate of construction waste in urban areas shall not be lower than 50%. By the end of 2023, the effective disposal rate of construction waste in the city will reach more than 80%, and the utilization rate of construction waste will strive to reach more than 80%.

The main direction of construction waste recycling is the production of reusable environmental protection building materials. The recycled construction waste is often composed of complex components, including bricks, plates, steel bars, plastics, wood, glass, concrete and other substances. It is screened by iron removers, mud removal, etc., leaving usable stones, which are processed and transformed into natural sand and gravel that can be replaced. The recycled aggregate is used to produce recycled bricks, colored tiles, roadside stones and other environmentally friendly building materials, and can be widely used in municipal facilities, water conservancy projects, "sponge city" construction and prefabricated buildings and other engineering construction fields to achieve circular development.

So how to produce and what equipment to choose? Construction waste is concentrated around the city. If a fixed production line is built, it belongs to the factory and needs to be approved by the environmental protection and other departments. It often has a long cycle, difficult construction, high cost, and high transportation costs for material transfer. Furthermore, in many cases, the distribution of construction waste generated by demolition and relocation is not concentrated, and the operating environment is complex. Taking a comprehensive consideration, the use of mobile crushing and screening stations is the best choice.
The mobile crushing and screening station of Bellian mining machinery manufacturer is a walking mobile factory, which can be composed of jaw crushers, impact crushers, cone crushers, vibrating screening equipment, conveyor belts, etc. according to the actual needs of customers. , to achieve coarse crushing, medium and fine crushing and screening of materials. The mobile crushing and screening station has two walking modes: crawler type and tire type, which can be configured according to the situation of the job site.

After the construction waste is crushed by the mobile crushing and screening station, most of the waste can be reused as renewable resources after being sorted and eliminated. It can also replace sand for building mortar, plastering mortar, and concrete cushion.
Mobile station, it can be said that "one machine in hand, walking vertically and horizontally", under various complex site conditions, it can stably and continuously produce, bringing benefits to customers.
