subject: Shanghai Zenith Construction Waste Crushing Equipment [print this page] There are two types of construction waste: Inert construction waste, Non-inert construction
waste. Non-inert construction waste is around 20% of the total and usually comprises bamboo,
timber, vegetation, packaging waste and other organic materials. Some of these can be
recycled while others are disposed of at landfills. In contrast, inert waste otherwise
known as public fill mainly includes construction debris, rubble, earth, bitumen and
concrete, aggragate, which can be used for land formation. Materials like concrete and
asphalt can also be recovered for construction use.
Construction waste is anything generated as a result of construction and then abandoned,
regardless of whether it has been processed or stockpiled. It comprises surplus materials
from site clearance, excavation, construction, refurbishment, renovation, demolition and
road works.
The impact of construction waste
The influence of construction waste to environment is featured with university, vagueness
and hysteretic nature. So we need construction waste recycling.
1.Waste land space and debasing the soil quality
As the increase of construction waste in city, the number of construction waste pile-up spot
becomes larger and so do the size of each spot. Whats more, for a variety of external
result, the air storage construction waste can fall into oil nearby and they will destroy
soil structure.
2.Affecting the air quality.
Under temperature and humidity condition, the waste pile will distribute some harmful gas;
some rotten waste throws off strongly smell, and bacterium and stive from the spot will fly
with the wind; a few building construction waste will give out the deleterious substance and
lead to the second-pollution to atmospheric environment.
3.Pollution to waters.
With the operation of ferment, rainwater, surface waters and ground water, the poisonous
parts of the waste will inflow to surface waters and ground water, which is used by city
human.
4.Destruction citys appearance environment.
City construction waste occupies large size of space and is in a muddle, which destroys the
image of city. And construction waste pile is usually the health corner.
5.Potential safety hazard.
Because of the unbending choice of pile spot, Potential safety hazard influence peoples
daily life.
Construction waste recycling
Building materials are crushed and screened on-site to produce building regulation standard
aggregates
Construction waste recycling is the separation and recycling of recoverable waste materials
generated during construction and remodeling. Packaging, new material scraps and old
materials and debris all constitute potentially recoverable materials. In renovation,
appliances, masonry materials, doors and windows are recyclable.
Construction waste crusher
In the crushing plant, construction waste is crushed into suitable size. The whole process
is as follows: First, construction waste enter into jaw crusher for primary crushing, then
into impact crusher for secondary crushing, final, the construction waste enter into the
cone crusher for fine crushing, then through screening machine, the suitable stones is
screened out.
Construction waste crushing process
recycling
Construction waste such as gravel, concrete, and other masonry material can be re-used as
buiding materials after crushing. After you collect metal from the construction aggregate,
the waste can be crushed. The complete crushing plant is consisted of jaw crusher, belt
conveyor, and vibrating screen. Usually we choose mobile crusher to crush stone materials.
Mobile crusher (protable crusher) is convenient, dont worry about the problems of crushing
