As is well known, construction waste can be utilized as a resource. For example, after the demolition of a building, the remaining old asphalt is crushed and screened, and remixed with recycled agents, new aggregates, and new asphalt materials in an appropriate proportion to form recycled asphalt concrete, which is used for paving road surface or base layers. Old bricks and tiles are crushed after being roughly divided, serving as lightweight brick aggregates and can also be made into floor tile materials and cement mixtures. Concrete blocks, which account for about 30% of the total construction waste, are also a valuable part of recycling and cannot be wasted. After being crushed, they are used to produce recycled concrete, recycled cement, or as roadbed materials.
Clever, have you also discovered the secret - the resource utilization of construction waste is inseparable from fragmentation and screening.
Overall, the recycling of construction waste can be divided into two directions: fixed construction waste recycling and disposal, and mobile construction waste recycling and disposal. The commonly used crushing equipment for the resource utilization and disposal of fixed construction waste is a primary crushing jaw crusher, a secondary crushing impact crusher or cone crusher, and a tertiary shaping sand making impact crusher (also known as a sand making machine). The crushing equipment used for the resource-based disposal of mobile construction waste is a crawler type mobile crusher and a tire type mobile crusher. Whether traveling with tracks or tires, the crushing equipment equipped on the frame, GEP, can be combined according to different crushing process requirements. jaw crusher, impact crusher, and cone crusher are relatively mature equipment, with convenient operation and maintenance, large crushing ratio, and long service life; Of course, it can also be run separately, and the selection of solutions is relatively flexible.
As for the equipment used in the screening and light matter separation process, GEP's flip-flow screen, circular vibrating screen, multifrequency screen, wind sifter, magnetic separator, and water flotation are all good choices, which can effectively improve the purity of sand and gravel aggregates. Of course, manual sorting can also be used, and low efficiency, low safety factor, and high labor cost are all issues that must be considered. In order to meet environmental standards, necessary dust and noise reduction equipment is also indispensable, after all, the cause we strive for is to eliminate garbage and not create pollution. You will find that the construction waste disposal production line is relatively cumbersome and equipped with many devices. An automated and intelligent GI intelligent system can simplify complexity and free hands. It also has powerful functions such as fault warning, real-time monitoring, and generating data reports. Although the initial investment ratio may be high, it is still cost-effective in the long run.
