Construction Waste:
Construction waste refers to the production activities engaged in demolition, construction, renovation, repair, construction industry, construction waste, waste concrete, waste masonry and other waste collectively. Construction dregs can be divided according to the generated source classification, construction waste, renovation waste, demolition waste, engineering mud; classification composition of construction waste can be divided into the muck, concrete blocks, rubble block, stone fragments, waste mortar, mud, asphalt block, waste plastic, scrap metal, scrap bamboo.
The Construction Debris treatment plant to take a physical or stone means, the use of active substances in the production of building materials in the construction waste treatment plant. Treatment resources can be divided into the "lower treatment resources and advanced treatment resources. "Lower resource processing including separation processing, sorted metal, wood, stone and other material directly recycling, brick, concrete, asphalt, concrete and other substances can be advanced use. "Advanced treatment resources, including the production of aggregate and new wall materials.
Construction waste should generate source segregation of collection, transportation mode. Building construction waste, renovation waste, demolition waste and mud shunt collection, transportation. Construction waste should be based on the need to end treatment, the progressive realization of the different separation and collection. Sanitary landfill collection area can be divided into the hazardous waste and other waste two categories; the backfill collection area can be divided into the muck of the garbage, hazardous waste and other garbage into three categories; resources to deal with the collection area can be divided into the backfill garbage, hazardous waste can be recycling garbage, garbage four categories.
construction waste disposal plan
Construction Waste Disposal Plan:
Construction waste, the government should minimization, recycling, sound and cyclic economic point of departure, laws and regulations, the recycling of construction waste is written to the developers of real estate development and transformation of villages, the house demolition responsibility contract; encourage and support enterprises to strengthen the construction waste recycling technology R & D investment; encourage and support the demolition enterprise of construction waste on-site scientific processing, recycling, construction waste production of goods brick, board and other new building materials; construction enterprises are encouraged to use these new buildings materials.
Urban construction waste resources and reduce the waste of land, the utility model provides a comprehensive urban construction waste treatment and utilization system, which the city construction waste into sand, soil and stones can take advantage of that to save the land , and generate value in use.
The new technology program: urban construction waste comprehensive treatment system includes a coarse crusher, secondary crusher, after separation and conveying device, after separation, in line with the standards of the stone was successfully transported to the storage bin, do not meet the The stone was once again returned to the secondary crushing equipment, broken again, so the cycle. Investment in urban construction waste using the coarse crusher, conveyer preliminary rough crusher broken into the secondary crusher crushing, secondary crushing garbage mixture separator conveyor fed, divided into small sand and stones of different sizes (including concrete blocks). The utility model with two broken broken into urban construction waste sand and suitable size stones, and the separation will be broken by separation machine junk mixture of fine sand and different size stones, sand and can further divided into sand and fine soil, stones and sand can be used the concrete raw or used for paving, fine soil can be used as urban greening soil resource utilization of urban construction waste, and save the land.
Henan Liming Heavy Industry Science & Technology Co., Ltd. of stone production line configuration is designed for customers by the project based on the site of the site survey and customer requirements. Liming Heavy stone production crushing equipment production handling capacity, low wear, broken equipment crusher run low cost of its significant features. Liming Heavy production of stone crushing equipment production line, PE jaw crusher initial coarse crushing, then the belt conveyor into PF impact crusher again shaping broken last screening after vibrating screen, Dan Zicheng products expected broken particles is divided into a number of customer needs, some unqualified stone jaw crusher by belt conveyor back or back to the impact crusher broken again, until broken into qualified materials.
Construction Waste Treatment Process:
Mixed construction waste: building garbage mixed with a lot of garbage, relying solely on the mobile screening stations can not be accurately sorting, to be used in processing the trite mixed garbage drum screening unit for accurate screening.
Concrete construction waste: is doped with a small amount of household waste (wood products, stone products, stone bags, etc.) construction wastes class garbage. For such garbage, to be used in mobile screening station for processing.
Construction Waste Recycled Aggregate Production Process:
1, feed and crude break
Shipped to dump heavy trucks after proper treatment, construction waste (materials) can be used in making stone aggregate production plants (and stone factories together) can be directly fed into the hopper, and can also be used loaders fed. Jaw crusher vibrating feeder into the rough broken. Vibrating feeder while construction waste fine soil sieve out, sent away under the belt conveyor.
2, the sorting system
The crude after breaking material using electromagnetic separator installed in the conveyor belt at the top of the scrap metal for recovery, and before entering the round shaker winnowing blown out and recovered by lightweight materials. Here should be appropriate to increase the artificial separation, in order to improve the quality of the separation, the lower vibrating screen materials entering the landfill backfill.
3, high-pressure washing system
Materials arrive screening broken belt conveyor, the conveyor above the dust controller for high pressure vortex sprinkler, high pressure water jet group, aggregate cleaning sprinklers, the sink cleaning spray device, through the spray of the water on the logistics from The dustfall role.
4, secondary and tertiary crushing system
Isolated from the high-pressure washing device available material inhaled some of the water, and therefore fed into the secondary impact crusher for crushing, the product was a cube, no dust flying; broken three times for the ultra-powerful cone grinder to change recycled aggregate physical characteristics; secondary, tertiary crushing the material again after the magnetic separator (recycling metal), Vibration filter export finished recycled aggregate selected through a sieve of 0-9mm, fine aggregate and 9-25mm coarse aggregate, or according to brickmaking the aggregates of the required size.
5, dust purification system
In the material inlet and outlet of each device has a suction outlet, dusty gas through a pipe into the precipitator. Bag filter, high efficiency filter bag expanded polytetrafluoroethylene (ePTFE) film filter bag. Use the closed blast plumbing fixtures and wet process to effectively reduce the plant's dust amount.
6, the automatic control system
The entire process of running the automatic control system, including the data acquisition system (DAS), the production process regulation and control system (MCS) device sequence control system (SCS), and interlock protection functions.
