Principles for Selecting Raw Materials of VSI Sand Making Machine
Building sand is valued by the engineering projects, which includes manufactured sand and
natural sand. The artificial sand is manufactured by crushing raw materials conducted by the
crushers and vsi sand making machine . There are three reasons for artificial sand being the
model of building sand that is advocated by the state. The first is to avoid the destruction of
riverbed caused by excavation of river sand, thus preventing the floods and security risks. The
second is to reduce the energy consumption and build price advantage. The exploration of
river sand needs to salvage, remove sludge, dry and other links. The artificial sand is some of
crushing and screening links.
Due to the large scale of artificial sand, the electricity consumption of per ton of sand is
relatively lower than river sand. Besides, the river sand resource is lower than the rock
resource, which needs lower resource tax, thus crusher machine creating the price advantage
of artificial sand compared with river sand. The third is the hard rock equipment that artificial
sand uses perfectly meeting the requirements of high-strength concrete. The current sand
making machine can fully meet the grading requirements of artificial sand, which makes the
performance for artificial sand better than the river sand.
The advocacy of manufactured sand is inev itable. But, the manufactured sand needs a large
number of raw materials. Although there are large amounts of rock resources, however, they
cannot be over exploited; otherwise, it will cause excessive deterioration of the ecological
environment. Some areas have already appeared the depleted condition of sand rocks,
especially in the eastern provinces that earliest develop the sand and gravel industry. So, how
to solve these problems?
Actually, we have lots of waste resources to utilize, including building wastes, slag, blast
furnace slag, gangue and so on. If we can use these wastes to manufacture san d, it will greatly
ease the shortage problem of sand rocks. There are many advantages to use sand making
machines to process these wastes into building sand.
Firstly , it is a kind of project that is beneficial to the environmental protection. Find places t o
address these wastes and turn them into treasure are advocated by the state. We will enjoy
preferential tax rebate.
Secondly, these wastes have lower prices. For the sand manufacturers, the purchase cost for
per ton of raw materials is lower than sand ro cks, which ensures the profit margins and is
equipped with relatively relaxed price range.
Lastly , the slag is the excellent raw materials of cement, which can also be the raw material of
building sand, which can improve the strength of concrete. The effec t is lost than the sand
manufactured by hard rocks.
