Municipal construction such as community demolition and road reconstruction will generate a large amount of construction waste. If a large amount of construction waste is abandoned, it will undoubtedly be a waste of resources. These construction wastes can be processed into gravel or sand according to different needs, which is a good infrastructure material.
Construction waste was originally discarded by people. After professional construction solid waste treatment equipment, it can be processed into gravel and sand that meet customer needs. The finished product has a rounded particle shape and common specifications of 0-5-10-15-20-30. Using waste construction concrete and waste bricks and stones to produce coarse and fine aggregates can be used to produce concrete and mortar of corresponding strength grades or to prepare building materials such as blocks, wall panels, and floor tiles; after adding curing materials, coarse and fine aggregates can also be used for highway pavement base; using waste bricks and tiles to produce aggregates can be used to produce recycled bricks, blocks, wall panels, floor tiles and other building materials. The slag can be used for road construction, pile foundation filling, foundation, etc.; the waste road asphalt mixture can be directly used for recycled asphalt concrete in appropriate proportions; the waste road concrete can be processed into recycled aggregate for the preparation of recycled concrete.
The process flow of construction solid waste recycling and reuse is as follows:
1. Primary crushing: The construction waste after manual sorting enters the crusher inlet for crushing, and then removes iron through the iron removal equipment. The separated magnetic materials such as steel bars are transmitted to the machine equipment through the belt conveyor and wait for comprehensive utilization.
2. Primary screening: The aggregate after crushing and iron removal is transmitted to the drum screen equipment. The drum screen equipped with a fan can cleanly separate the fine paper scraps, plastics, wood residues, etc. in the material. The recycled aggregate can be processed and recycled, and the light materials can be reshaped and processed.
3. Water washing screening: The cleanliness rate of the recycled aggregate after the drum screen screening reaches more than 80%. The fine light materials and sludge can be screened again through the flotation machine equipment to improve the application effect of reprocessing.
4. Circulation system: Construction waste can realize a complete set of crushing, screening and impurity removal production process under the above treatment. Slightly larger materials can be returned to production and processing again through belt conveyors, forming a closed-loop circulation system to improve the efficiency of the crushing process.
5. Harmless production: On-site dust removal fog cannons, sanitation sprinklers and other noise reduction and dust removal equipment are used to reduce site dust and secondary environmental pollution as much as possible in the construction and decoration waste treatment process, prevent adverse damage to the surrounding environment, and achieve harmless green and environmentally friendly production.
As a professional crushing and screening equipment manufacturer, we have a full set of mobile crushing and screening stations and fixed construction and decoration waste treatment production equipment research and development and production technology, including crushing systems, screening systems, sorting devices, and conveying systems. At the same time, we can also equip users with sufficient power devices and mobile devices.
The price of construction solid waste treatment equipment is a topic that everyone is concerned about. If you want to find a device that is both affordable and easy to use, you must first choose the right manufacturer. We are a large-scale, strong, environmentally friendly crushing and screening equipment manufacturer with a wide variety and full range of models. In addition to producing equipment, it is also responsible for direct sales, and one unit is also priced at the factory.
