Construction waste shredder

The construction waste shredder can processes more than 800 tons construction solid waste one day.

In the process of urbanization, construction waste as products of metabolism in the city has ever been the burden of urban development, many cities in the world have ever faced the situation of garbage siege. China is in a stage of rapid development of urbanization, construction waste has become a headache. According to the relevant department statistics, the average expectancy life of the building is 32 years. Disposal the solid waste poduced by building demolition each year has become a must be of concern. China is now producing about 400 million tons of construction waste each year in the city, which does not include road maintenance of solid waste generated each year.

China Construction waste industry started late, but through years of development, China State Construction waste disposal industry beginning to take shape, waste disposal has been a significant increase in market capacity, market penetration is rapidly increasing, the number of businesses into the sanitation sector is also rapidly increasing. Now that China’s construction market has grown from importing waste into the period of growth, and move into maturity and positive.

With the environmental issues being taken seriously, energy saving, environmental protection became the theme of the national development , opportunities have provided for the construction waste disposal industry development. The average annual growth rate of construction waste in the world is 8.42%, while China Construction waste growth rate is 10% or more. The world’s generated 490 million tons of construction waste each year, in China alone each year the city produces nearly 4.5 billion tons of construction waste construction. China’s urban construction waste accumulated stock pile has reached 27 billion tons. In such a huge pressure of waste, we have reason to believe that building the waste disposal industry will become the future star of the domestic industry.

European and American countries have set legislation for recycling of construction waste, recycling rate in European countries for construction waste reached 95%. In recent years, China’s “The Circular Economy Promotion Law of the People’s Republic of China” and the “Law of the People’s Republic of China on the prevention and control of environmental Pollution by solid waste” have been passed, has upgraded the solid waste recycling to another new height.

At present, China is in the period of rapid development, according to the relevant department statistics, the expectancy average life of the building is 32 years. Disposal the solid waste poduced by building demolition each year has become a must be of concern. China is now producing about 400 million tons of construction waste each year in the city, which does not include road maintenance of solid waste generated each year.

European and American countries are now recycling of construction waste has been legislation, European countries for construction waste recycling rate reached 95%. In recent years, China’s “Circular Economy Promotion Law of the People’s Republic” and the “People’s Republic of Solid Waste Pollution Prevention Law”, the solid waste recycling to upgrade to another new height.

In the twinkling of an eye, bricks piled up like a mountain, concrete blocks and other construction waste were changed into powder after crushed by construction waste shredder, which can be used as raw materials for production of bricks; the whole process with environmental protection, energy saving, emission reduction and so on. This “guy” is a length of about 25 meters crusher, it is also called (system) in waste disposal machinery building industry .

Construction waste shredder is a “monster”, it can “swallow” construction waste and “spit” recycled sediment. Crusher in busy operation, the belt is driving, the demolition site of the brick, concrete, broken tiles, etc. through a belt drive, all feeding into its “belly” (Container). It looks like the container can hold brick 1-2 tons, which is massive, this construction waste shredder can be kept eatting bricks and other garbage as long as the machinery does not stop, and it is generosity to every stytle of construction waste, whether it is brick or concrete. It is understood that this “monster” called construction waste disposal machine (system), can digest construction waste more than 800 tons per day. Just think, once this construction waste shredder promoted effectively, the effective conservation of building resources to address the plight of construction waste pollution.

The spit of sand powder proced by the construction waste breake after the brick and other construction waste were crushed, which can be used of in the construction site where it is needed, such as the basement backfilling. Then they can be used on the brick wall, brick sidewalks and parking on the lawn of the lattice bricks. Bricks need not to be burn, but the press-formed, truly change the construction waste to treasure.

The value of this machine is about $ 3 million each, including crushers, excavators and other equipment. Evety shredder needs six employees to operate, theny are separately arranged in the safety inspection, feeding, loading, electrical, head of the different positions, but the operation is very simple.

In general, the construction waste, such as bricks are crushed into powder by mechanical equipment, the process will be raised dust, noise and so on. However, the reporter approached the shredder and found that this worry is unnecessary, the machine issued a “buzzing” sound, but the noise is not large. He explained that he will not exceed the time for urban management department, the construction waste shredder has installation of a noise reduction facilities.

In addition, there is no phenomenon of dust filled in the process of crushing construction waste. Although the construction waste shredder in middle of the brick and concrete, but almost can not feel the dust. The top side of the machine is watering the dust, also equipped with cleaning equipment to reduce the decibels, dust, to ensure that no nuisance.

It is important for construction waste recycling, reduction, sound, which can save landfill costs and a large number of landfill sites, reduce environmental pollution, reduce the natural sand and gravel mining, protect the natural resources and the human environment. It is conforming to sustainable development strategy.

Some experts predict that there will be a “ten top emerging technologies”in the next 30 years, in which the “waste” of emerging technologies is listed as the second. Economically developed international countries are actively exploring the waste into a resource and play it as a new create a new large industry. They established a technical approach, the scientific and organizational structure of the new model, to ensure that the  control  of the main waste flow and the recycling of majority of construction waste, to achieve  a local construction waste digestion .

The usage of construction waste breaking machinery and equipment in construction waste recycling is a new starting point, also it is an important part of recycling economy. In the process of recycling and waste materials recycling process, the construction waste shredder not only solve the shortage of resources, while reducing waste emissions, described as “double benefit.” May not be long before, with the development of technology, construction waste will no longer be waste, but into a “gold.”

Solid waste is classified into three main types by making reference to the sources of waste and the institutional arrangements for waste collection and disposal. These three types of solid waste are municipal solid waste, construction waste and special waste. The detailed interpretations of some commonly used terms are described below.

Municipal solid waste includes domestic waste, commercial waste and industrial waste.

• • Domestic waste refers to household waste, waste generated from daily activities in institutional premises and refuse collected from public cleansing services. Public cleansing waste includes dirt and litter collected by the Hygiene Department, marine refuse collected by the Marine Department and waste from country parks collected by the Agriculture, Fisheries and Conservation Department.

• • Commercial waste is waste arising from commercial activities taking place in shops, restaurants, hotels, offices, markets in private housing estates, etc. It is collected mainly by private waste collectors. However, some commercial waste is mixed with domestic waste and collected by the Hygiene Department.
• • Industrial waste is waste arising from industrial activities and does not include construction waste and chemical waste. It is usually collected by private waste collectors. However, some industries may deliver their industrial waste directly to landfills for disposal.

• • It should be noted that there are bulky items like furniture and domestic appliances which cannot be handled by conventional compactor type refuse collection vehicles. These items are regarded as bulky waste and are usually collected separately. They may come from residential premises, commercial and industrial activities.

Construction waste (previously known as construction & demolition waste) is a mixture of surplus materials arising from site clearance, excavation, construction, refurbishment, renovation, demolition and road works. Over 80% of construction wastes are inert, which include debris, rubble, earth and concrete, are suitable for site formation and land reclamation. When properly sorted, materials such as concrete and asphalt can be recycled for use in construction. The remaining non-inert substances in construction waste, which include bamboo, timber, vegetation, packaging waste and other organic materials, are not suitable for site formation or land reclamation and are disposed of at landfills. Overall construction waste received at landfills includes construction waste from construction sites and waste concrete that is generated from concrete batching plants and cement plaster/mortar manufacturing plants not set up inside construction sites.

Special waste is waste that requires special disposal arrangement. It includes abattoir waste, animal carcasses, asbestos, chemical waste, clinical waste, condemned goods, dredged mud and excavated materials, sewage treatment and waterworks. treatment sludge, grease trap waste, livestock waste, sewage works screenings, waste tyres, furnace bottom ash, pulverised fuel ash, etc.

Chemical waste can be any substance arising from any process or trade activity which contains chemical in such form, quantity or concentration that can cause pollution to the environment or become a risk to health.

Current classification of solid waste

Note: Part of the waste generated from schools, government offices, government markets, etc. was mixed with household waste and/or public cleansing refuse during the process of collection carried out by the Hygiene Department.
