With the development of China's industrialization and urbanization and the reconstruction of shanty towns in most of the provinces in recent years, there has been an increase in solid waste of construction waste. In 2015 and 2020, the total amount of construction waste generated in China will be approximately 1.55 billion yuan annually. 24 billion tons, accounting for 40% of urban waste, is expected to reach a peak in China's construction waste generation by 2020; in 2015, China's industrial solid waste production will reach 3.221 billion tons; by 2017, China's industrial solid waste production will be Breaking 5 billion tons. At the two sessions last year, it was mentioned that increasing the solid waste disposal and recycling and industrialization development of construction wastes has a significant role in promoting urban environment, building livable cities, and a “two-type society”, and can bring about sustainable urban development. Great economic, social and environmental benefits.
"Building rubbish is a misplaced resource." In fact, construction waste is not real garbage, it is an effective resource, and it is the “second resource” of the construction industry. Most of the waste in construction waste can be reused after being sorted, removed or crushed. This is a promising environmental protection industry and a low-carbon economy.
In order to meet the needs of more customers, construction waste is crushed, light material separation can be combined with the introduction of a new construction waste crusher, the set of production line out of brick speed, reasonable design and stable performance, process reliability, smooth operation, high production efficiency, Pressing bricks have high forming pressure. Because of the limited pressure, it is very difficult for general block forming machines to combine materials with relatively complex construction wastes. Therefore, the bricks produced are very effective.
At present, all parts of China are vigorously developing urban construction. The amount of construction waste derived from the transformation of shantytowns and urbanization has reached more than 40% of the total amount of existing waste. According to estimates by authoritative departments, if buildings are used compared with solid clay bricks, Waste production of 100 million standard bricks can reduce the borrowing of 160,000 cubic meters and save about 120 acres of arable land. At the same time, it can absorb more than 300,000 tons of construction waste, and save 100 acres of land to be stored. The two projects can collectively save 220 acres of land. The utilization of construction waste resources is conducive to reducing ecological pollution, promoting energy conservation and emission reduction, and effectively improving the urban environment. It is a real project that benefits the nation and the people.
In the construction waste temporary storage yard, the excavator sent the construction waste to the Giant Heavy Industries Mobile Crushing Plant for crushing into pellets of different sizes, which were then conveyed to the screening station through a conveyor belt. After screening, construction waste becomes a reusable aggregate for the production of prefabricated building parts and components, or replaces parts of sand and stones, which not only solves the problem of construction waste dumping, but also reduces the production cost of building materials. .
