Nowadays, the river sand resources are decreasing gradually and the government implemented strict restrict measures on the excavation and exploitation of river sand. In addition, with the intensification of market competition and the acceleration of urbanization, the crusher and vsi sand making machine industry must build equipment upgrading awareness and production quality awareness in order to survive and development in the survival-of-the-fittest competition tide.
The steady development of the sand maker industry makes up for the shortage of the building sand. Even though the river sand and natural sand have many advantages, the natural sand may not satisfy the higher and higher requirement of the buildings quality level due to the limits of geographical distribution and production condition of natural weathering. The present sand making technology in our country has been pretty mature, and these shortcomings of the natural sand can be overcome through the crushing machines such as impact crusher and sand making equipment.
At first people had doubt on the artificial sand. However, with the development of society, the artificial sand gradually demonstrates its superiority and people do not repel it any longer. Making reasonable use of natural river sand and developing artificial sand has become one of the national policies.
The reasons why artificial sand can replace natural sand lie in two aspects: one is that in order to protect the ecological equilibrium, the government will inevitably limit the excavation of natural sand, so that the supply amount of the natural sand for the construction will decrease; the other one is that with the development of science and technology and national economy, the equipment and technology for manufacturing artificial sand have developed to a certain height, and our country is able to manufacture excellent sand and stone aggregates that conform to the application requirements.
Although the sand making equipment in...
