These seemingly useless concrete blocks mixed with pavement cement blocks, waste, waste rock, and garbage are only to be sorted and recycled, and then can completely "turn waste into treasure" and realize its economic value.

The traditional treatment method only involves the physical migration of concrete construction waste, which will bring a safety hazard, result in huge pollution of water resources, land resources and air resources, and occupy a large amount of land area.

1. Production of coarse and fine aggregates: Combined with the strength grade of construction waste, concrete aggregates with different hardness and grain size can be processed, and can also be used for road pavement base filler.

2. The production of new, environmentally friendly building materials: Recycled concrete construction waste and cement blocks are often used to manufacture environmentally-friendly bricks, insulation materials, insulation walls around the outside of the wall, dry mortar, etc.

4. Temporary road laying: A large number of cushions are required in the road construction process, so the concrete construction waste can play a huge role in the laying of road cushions and temporary roads.

Also, concrete waste is always mixed with scrap wood, which can be used for wood regeneration. For the waste wood in construction waste, the well-preserved can be directly used for reconstruction, and the damaged materials can be raw materials of regenerating wood, or used in the paper-making field.

The specific use of crushed concrete waste also depends on the processing effect of the selected equipment. At present, there are two kinds of crushing production lines for processing concrete waste, one is fixed concrete crushing production line, and the other is mobile crushing production line.

The fixed type is suitable for some stone factories and concrete wastes need to be equipped with professional crushers, iron removal equipment, professional dust removal and noise reduction equipment, vibration feeders, magnetic separators, flotation machines, vibrating screens, belts, etc., which forms a complete production line for concrete waste treatment.

The mobile type is more suitable for housing developers and concrete waste disposal companies. It is easy to transport and can be pulled into the construction site for quick operation, which saves the space without having to build a special factory.

It can produce different aggregates with various specifications, achieving the needs of different customers. This kind of mobile construction waste treatment equipment is widely used, and its main features are as follows:

The most commonly used crushing machines are jaw crushers, hammer crushers, and impact crushers. Which one to choose, users need to make choices according to their own needs and actual conditions, and the most important thing is to make choices according to the characteristics of the crushers.

Uses: The impact crusher can handle the crushing of various coarse, medium and fine materials with a length of less than 500 mm and a compressive strength of less than 350 MPa. The discharging granularity can be adjusted as needed to adjust the gap between the hammerhead and the counterattack plate.

Uses: Jaw crusher is a piece of early crushing equipment. Because of its simple structure, firmness, reliable work, easy maintenance and overhaul, and relatively low production and construction costs, it is still widely used in metallurgy, chemical industry, building materials, etc.

Concrete waste is made up of chemical constituents of silicates, oxides, hydroxides, carbonates, sulfides and sulfates, which means that it is soft and has a certain strength, hardness, impact and wear resistance.

1. The impact crusher can effectively treat materials with large moisture content and prevent clogging of the crusher. Therefore, when the concrete has a large moisture content, the impact crusher is the best choice.

2. The hammer crusher has less investment, large output and low power consumption. When the user has a large demand for production and considers the investment problem, hammer crusher is the best choice.

3. The jaw crusher is widely used, especially for one-stage crushing, which is to crush large materials into two-stage crushing machines. If the feeding materials are large, it must be crushed by jaw crusher.

There are many manufacturers of concrete waste crushers. Most of the famous brand concrete crusher manufacturers provide perfect one-stop service before-, during- and after-sales, which can save the cost of manufacturers, so the price of the concrete crusher will be lower.

Its main features are that it is movable and walking freely, thus, the transition is more convenient to ensure safe operation. The station's output ranges from 10 to 650 tons per hour, and one production line can simultaneously produce four sizes of stones, sand and powder.

The mobile crusher can carry jaw crushers, impact crushers, cone crushers, vibrating screens, conveyors, etc. The complete ore processing line has significant quality, performance and price advantages, and is widely used in highway, railway, national defense and construction.

The crawler-type: crawler-type drive has the advantages of lowering the chassis of the whole machine, strong driving stability. The whole machine can work at complex sites with strong adaptability, especially good for climbing work.

It can also quickly enter the work site for immediate operation. The whole machine adopts steel structure which is sturdy and durable. Modular assembly makes various devices work together without affecting each other.

It can be divided into jaw crusher type, cone crusher type, hammer crusher type, impact crusher type, etc., due to the different types of crushers it carries, its function and adaptability are also different.

The jaw crusher is suitable for coarse crushing, the cone crusher and impact crusher are suitable for fine crushing, the hammer crusher can be used for one-time shaping, and the impact sand maker is used for sand making. In short, the user needs to combine his own needs when configuring the machines.

The two-machine mode usually consists of a mobile jaw crusher + a mobile cone crusher or a mobile jaw crusher + a mobile impact crusher. The two stations form a production line covering the processes of coarse crushing, fine crushing, screening, feeding and transportation;

When configuring a mobile crushing station, there have differences between the large output and small output. Generally, the line is 40-50 t/h. The small output can be matched into one mobile station and the large one generally requires two or more. Next, lets take a look at the specific configuration of the mobile crusher.

As far as the situation on the market is concerned, there are two main types of suppliers of mobile crushers. One is to have their own factories and sell the mobile crushing station by themselves. These suppliers are called direct sales manufacturers. And the other one is that there have no factories of its own, which means that they need to purchase the mobile crushing plant from others, and then sell the machines by themselves. This kind of supplier is called a sales-oriented manufacturer.

For these two manufacturers, the mobile crusher and other equipment processed by the former are closer to the factory price. The latter, because of the price difference in the middle, will be more expensive than the direct-selling manufacturer.

From the above, it can be seen that the direct-selling manufacturers are more favorable in price. Also, for direct-sales manufacturers, the problems of after-sales and accessory support of mobile crushers can be better guaranteed.

The designed output is generally 30-350 tons per hour. According to different technological requirements, we can also equip the dust collector, cone crusher, or other cement crushersto meet the different production needs of customers.

In the production process, large stones are evenly sent to the jaw crusher by a vibrating feeder for coarse crushing (primary crushing), then sent to the impact crusher by the belt conveyor for secondary crushing. After that, all the stones will be divided into three different sizes on the vibrating screen. The large-sized stone which beyond the specification will be sent back to the impact crusher by the belt conveyor for re-crushing, and then sent to the vibrating screen again forming closed-circuit multiple cycles until the completion of production.

Our stone crushing plant has a high degree of automation. Except for equipment start-up, shutdown, and daily maintenance, the whole plant requires almost no manual operation.

The product quality completely reaches the GB14685-2001 standard, which can be regarded as aggregate for high-grade highway, railway, water conservancy, concrete mixing plant, and other industries.

The performance of the stone crushing plant can be judged according to the product quality. There are mainly two quality indexes of crushed stone: the ratio of elongated and flaky particles and the content of the powder. If these two indicators exceed the specified range, the product quality is unqualified and cannot be used in large projects. The quality of crushed stones produced by our crushing plant is in line with the relevant standards. The content of elongated and flaky particles and powder in the crushed stone is very small and the product particle size is uniform, the particle shape is good with no internal crack, the compressive strength is high, and the granular composition is reasonable.
