subject: Cone Crusher to promote the development of building sand [print this page] For construction, the construction industry, the sand is essential to one of the important
aggregate materials. However, with the exploitation of resources, reduced day by day, the
sand has become a scarce resource. The cone crusher,jawcrusher, sand making machine such as broken equipment, can be mineral, river gravel,
tailings, slag processing resources such as sand, to meet the amount of sand used in
construction.
Although the scarcity of natural sand, but the building will continue to address the
rapid reduction of the amount of the status of river sand, one has to find another way out
--- Sand. According to an estimated worldwide annual demand for sand used in construction of
about 600 million tons. The application of most parts of the world is a natural sand, and
natural sand resources is a local resource, is short-term non-renewable resources within.
With the growing infrastructure development and environmental protection needs, many regions
in the world to gradually reduce the natural sand resources, decline in the quality of sand,
limit or ban on logging natural sand mining situation, concrete sand supply and demand is
particularly prominent. The increasing price of sand, sand or no sand is available peak, not
only the environmental cycle chain of resources is not complete, but also affected the
progress of the project construction.
In addition, with the rapid development of concrete technology, construction of the
widening, especially in the most affecting the people of the high-speed rail construction.
Technical requirements for its sand is getting high, especially in high strength and high
performance concrete is very strict on the aggregate, for example, high-speed rail, and
highway construction, to meet their requirements, the more the number of natural sand to
less or no. Therefore, the development of new sand source, the use of artificial sand
development is imperative. Meanwhile, the world has a lot of metal ores and non-metallic
minerals, mining and processing associated with about 40% -60% produced tailings, tailings
no reasonable use of a considerable waste of resources, occupation of land, creating new
environmental pollution, And if after a cone crusher or a crusher sand making equipment such
as sorting and processing, and many sand tailings can be made to both solve the problem of
sand sources and environmental pollution, and improve the resource utilization, to form a
comprehensive benefits.
Now, with infrastructure development, the gradual reduction of natural sand, the
application of international human has become the trend of sand, artificial sand
manufacturing machinery and equipment has reached a certain level, while the domestic rise
of a new batch of artificial sand making equipment into the more advanced ranks. Shanghai
Zenith Co., Ltd. is one of them, the production of a series of crusher, cone crusher, sand making
machine, etc., can process various ores, river gravel, slag, tailings and other materials,
the processing to the production of artificial sand completely replace the natural sand to
complete the construction of major projects, which create the Sand will promote the
development of the construction sector.
