In recent years, railways, highways, high-speed rails, and high-speed rails have been built in most areas. As cities become more and more convenient, a large amount of construction waste has also been generated. Today in the era of environmental protection, more than 95% of the ingredients have been broken, after cleaning and grading, it is mixed with the gradation in a certain proportion, which can replace the green material of natural aggregate such as sand and stone. It saves resources and is clean and environmentally friendly. The green commercial concrete with recycled aggregate as the core has achieved a win-win victory for the sustainable development of construction resources and the environment. So, where does the value of construction waste reuse specifically reflect?
1. Production of coarse and fine aggregates. According to the strength grade of construction waste, concrete aggregates of different grain sizes and hardness can be processed, and it can also be used as filler for highway pavement base.
2. Manufacturing new and environmentally friendly building materials. After being recycled and processed, waste materials and cement blocks in construction waste are often used to make new materials such as thermal insulation materials, environmentally friendly bricks, dry-mixed mortar, and thermal insulation walls around the walls.
3. Concrete admixture. The waste bricks and tiles in the construction waste is a kind of burnt clay material. When it is crushed and rolled into a powder material, it has pozzolanic activity and can be used in concrete as a concrete admixture.
4. Temporary road paving. In the process of highway road construction, a large number of cushions are needed, and the crushed sand and gravel aggregates of construction waste can be well used in the 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 seriously damaged materials can be used as raw materials for recycled boards or in the field of papermaking.
The mobile construction waste crusher directly removes iron from large pieces of construction waste, crushes them in multiple stages, and screens them according to certain discharge specifications. One machine can build a factory, has strong adaptability, and is more flexible in configuration. It can be processed according to raw materials the situation, output and finished material requirements can be flexibly matched. The complete set of construction waste treatment equipment is classified as follows: According to the driving device: it is divided into tire type and crawler type. The tire is semi-mobile and needs to be driven by a semi-trailer; fully automatic, self-controlled, remote control mode, higher intelligence. According to the configuration of the crusher, it can be divided into jaw type, cone type, counterattack type, heavy hammer type, screening machine and sand making machine. Due to the different equipment installed, it can be further divided into coarse crushing, medium/fine crushing and screening. The mobile construction waste crusher has the following advantages:
1. Flexible configuration and strong mobility, flexible configuration and combination. According to different engineering needs, it can be configured into a three-stage crushing and screening system combining coarse crushing unit, medium crushing unit, and fine crushing unit, or it can operate independently. Each crushing unit has light weight, short length, strong adaptability, strong maneuverability, easy to move and flexible combination.
2. Efficient, fast and flexible. The mobile crushing and screening plant can be adjusted from the transportation state to the working state in a short time, and can quickly establish a temporary and periodic crushing production line, quickly transfer, put it into use, and avoid the fixed and tedious pre-planning and construction cycle Investment to fully improve the utilization rate of equipment.
3. Save construction waste transportation cost and avoids secondary pollution. The nearby processing mode of the mobile crushing production line completely eliminates the transportation costs incurred during the transfer of construction waste. In response to increasingly strict environmental protection policies, secondary pollution caused by construction waste transportation can be effectively avoided.
4. Environmental protection and green production. The current environmental protection situation is becoming more and more severe. All equipment is not environmentally friendly and cannot be operated. The mobile construction waste crusher currently produced is environmentally friendly. In addition, spraying and dust removal devices are used during operation to reduce dust and noise. The effect is very good.
5. Simple operation, convenient installation, complete supporting facilities, quick installation, and production can be run when power is connected, simple operation control, single-stage integrated operation control, or multi-stage interlocking control.
