The value of construction waste reuse, advantages of mobile construction waste crusher, which crushing equipment is good for processing construction waste, mobile construction waste crusher
In recent years, my country's infrastructure projects have developed rapidly, and most areas have built railways, highways, expressways, and high-speed rails. As cities become more and more convenient, a large amount of construction waste is also produced. In today's environmental protection era, more than 95% of construction waste is crushed, cleaned, classified and mixed with grading in a certain proportion, which can replace green materials such as sand and gravel and other natural aggregates. Save resources, clean and environmentally friendly. Green commercial concrete with recycled aggregates as the core achieves a win-win situation for the sustainable development of construction resources and the environment. So, in what aspects is the value of construction waste reuse reflected?
1. Production of coarse aggregate and fine aggregate. According to the strength level of construction waste, concrete aggregates of different particle sizes and hardness can be processed, and can also be used as fillers for road pavement base layers.
2. Manufacture new environmentally friendly building materials. Waste materials and cement blocks in construction waste are recycled and used to make new materials such as insulation materials, environmentally friendly bricks, dry-mixed mortar, and insulation walls.
3. Concrete admixtures. The waste bricks and tiles in construction waste are burned clay materials. When crushed and rolled into a powder material, they have pozzolanic activity and can be used in concrete as concrete admixtures.
4. Temporary road paving. During the construction of highways, a large amount of cushion is required, and construction waste crushed sand and gravel aggregate can be well used for bottom cushion and temporary road paving.
5. Wood regeneration. Some well-preserved waste wood in construction waste can be directly used for building reconstruction, and severely damaged wood can be used as raw materials for recycled boards or for papermaking.
Which crushing equipment is best for processing construction waste?
The mobile construction waste crusher directly removes iron from large pieces of construction waste, performs multi-stage crushing, and screens it according to certain emission specifications. A factory can be built with one machine, with strong adaptability and more flexible configuration. According to the raw material processability, output and finished product demand, complete sets of construction waste treatment equipment can be divided into the following categories: According to driving device: divided into tire type and crawler type. The tire is semi-mobile and needs to be towed by a semi-trailer; it is fully automatic, self-propelled, remote-controlled, and highly intelligent. According to the supporting equipment of the crusher: it is divided into jaw type, cone type, impact type, hammer type, screening machine, sand making machine, etc. Due to the different equipment installed, it can be divided into coarse crushing, medium/fine crushing and screening.

Mobile construction waste crusher has the following advantages
1. Flexible collocation and strong maneuverability. Flexible configuration and combination. According to different engineering needs, a three-stage crushing and screening system can be configured as a combination of coarse crushing unit, medium crushing unit and fine crushing unit. It can also be run independently on a stand-alone machine. Each crushing unit has the characteristics of light weight, short length, strong adaptability, strong maneuverability, easy movement, and flexible combination.
2. Efficient, fast and flexible. The mobile crushing and screening station can be adjusted from transportation state to working state in a short time, and can quickly establish temporary and periodic crushing production lines. It can be quickly transferred and put into use, avoiding cumbersome pre-planning and fixed construction periods. Invest to fully improve equipment utilization.
3. Save construction waste transportation costs and avoid secondary pollution. The nearby processing mode of the mobile crushing production line completely saves the transportation costs incurred during the transfer of construction waste. In response to increasingly stringent environmental protection policies, secondary pollution caused during the transfer of construction waste can be effectively avoided.
4. Environmentally friendly operations and green production The current environmental protection situation is becoming increasingly severe. All equipment is not environmentally friendly and does not work. The mobile construction waste crushers currently produced are environmentally friendly. In addition, spraying, dust removal and other devices are used during operation to reduce dust and noise. The effect is very good.
5. Simple operation and convenient installation. The supporting facilities are complete and the installation is quick. Production can be started after powering on. The operation control is simple, and it can be controlled by single-level comprehensive operation and multi-level chain control.
