Sand Production Line With Less Dust Production And Environmental Protection

Last Update:2020-05-13 22:10:04

In the traditional sand making process in China, one is dry sand making, the other is wet sand making. Over the years, there are two major problems beset by domestic artificial sand making, one is environmental protection, the other is that the fineness modulus, stone powder content and water content of the finished sand are difficult to control. These two problems cannot be solved by both dry and wet sand making processes. Let's take a look at these two problems Sand production.

Although the problem of high content of stone powder can be solved by dry sand making. However, the dust in the production process is very large, which causes serious environmental pollution. Only closed production can avoid large-scale dust diffusion, and the content of stone powder often exceeds the standard. The silt less than 0.08mm in the stone powder can not be separated, which affects the quality of concrete and increases the construction cost.

In order to make up for the shortage of dry sand making and wet sand making, the sand making experts have made unremitting efforts. The environmental protection semi dry sand making technology has been identified by the expert group and has been put into use. The semi dry sand making technology not only saves the production cost through the recycling of wastes, but also creates objective economic benefits through the recycling of resources. Here is our case site in Yangquan, Shanxi:

Liming heavy industry Vu dry sand making system is an upgrade of Liming heavy industry on the basis of the original dry sand making system. It adopts highly intensive tower type totally enclosed layout, integrating dry sand, particle shape optimization, stone powder control, grading adjustment, water content control and environmental protection treatment. The quality of manufactured sand produced by liming heavy industry is comparable to that of natural sand, which is sand, cement and concrete The development of industrial chain creates new opportunities and values.
