What is construction waste? Construction waste refers to the muck, waste concrete, waste masonry and other wastes produced by people in the production activities of the construction industry such as demolition, construction, decoration and repair. According to the source of generation, construction waste can be divided into construction waste, decoration waste, demolition waste, engineering mud, etc.; according to the composition, construction waste can be divided into muck, concrete blocks, crushed stones, brick fragments, waste mortar, mud, asphalt block, waste plastic, waste metal, waste bamboo and wood, etc.
Where can construction waste be used?
1. Bricks, tiles, etc. can be screened and crushed layer by layer and used as recycled aggregate to prepare low-grade recycled aggregate concrete for foundation reinforcement, road engineering cushions, hollow bricks, air-permeable bricks, etc.;
2. In addition to being reused as formwork or building materials, waste wood can be crushed and turned into scraps for use as papermaking raw materials or fuel;
3. Scrap steel bars, nails, screws, etc. can be sorted out and sent back to the steel plant for refining.
In the process of uniformly conveying construction waste to the crusher through the feeder, the conveyor belt will be equipped with an iron removal device, which attracts the unbreakable materials such as nails and steel bars hidden in it by magnetic force, and then sends it to the crusher for crushing treatment; After the construction waste is coarsely crushed, the second crushing process will be crushed according to the user's requirements for the particle size of the finished product. The material discharged from the discharge port should be of the quality required by the user; cleaning and impurity removal are generally placed at the back of the entire link, the main purpose is to improve the quality of the material. Generally, a sand washing machine is sufficient. After the sand washing machine is cleaned, the grains of the material are uniform, which can meet the sand standard of recycled aggregate.
Fixed construction waste crushing equipment
The fixed construction waste crushing production line is the construction waste treatment enterprise selects a fixed area, builds fixed infrastructure and fixed equipment, and centrally processes construction waste. This method is a traditional construction waste treatment method. Its advantage is that it has strong processing capacity and can adapt to the treatment of various complex components of construction waste. There are many complex components in the construction waste, or the site lacks on-site crushing space. Consider adopting this approach. There are many fixed series of construction waste recycling equipment, including jaw crusher, impact crusher, hammer crusher, cone crusher, roller crusher and other series to choose from, whether it is small or large output all can meet (such as 50t/h, 100t/h, 300t/h, 500t/h, 1000t/h, etc.).
Mobile construction waste crushing equipment
The mobile construction waste crusher is a production model that uses a combination of mobile crushing stations and mobile screening stations to process on-site construction waste at the point of generation. The composition of the construction waste processed is relatively single. It is suitable for waste concrete, waste bricks, and road asphalt, construction waste such as concrete waste. The advantage of this treatment method is that it can be dealt with in a targeted manner. Because the construction waste generation points are not concentrated, and the amount of production is not large, the mobile construction waste crusher is particularly suitable for occasions where the construction waste generation cycle is long and the area is large. Follow up the progress of demolition at any time for timely crushing, effectively alleviating secondary pollution and unnecessary transportation costs caused by construction waste transportation. The mobile series of construction waste recycling equipment is divided into tire type and crawler type. It has good transfer ability and is very suitable for construction waste. A machine includes four major systems: conveying, screening, feeding, and crushing. Single-machine operation or multi-machine joint operation can make the disposal of construction waste easier, without the need to transport materials over long distances, occupy a small area and save costs.
