The shortage of natural sand makes the artificial sand necessary. For the production of artificial sand, SBM Machinery exports remind you that choosing a right sand production process for artificial sand is just like water for fish, which is of high efficiency. Currently, there are two ways of ore milling equipment: wet type ore milling equipment technology and dry type ore milling equipment technology. So, which one can be selected according to individual circumstance? At first, the difference between these two methods should be made clear, and then you will get the answer.
Wet type ore milling equipment technology is generally used in South China or areas with rich water resource. The traditional process is crusher from large size to medium, then to small size which is less than 25mm.After that, the gravel will be put into rod mill for ore milling equipment. Finally, the spiral separator will take off the mud and emerge the powder. It is widely used in hydroelectric sites for artificial ore milling equipment in the 1990s.With the application of sand maker, especially since the 1996 Three Gorges Water Conservancy and Hydropower Engineering applied the vertical impact crusher to produce artificial aggregates, which made water conservancy, hydropower engineering and construction industries develop quickly in artificial ore milling equipment.
Dry type ore milling equipment line: the so-called 'dry' means that when making artificial sand, it doesn’t use water to get rid of mud from sand, but uses separator to reduce the amount of mud in order to obtain a better guarantee of the quality and grade of sand.
These two methods depend on geographic locations and conditions of the plant. Literally speaking, as the name suggests , one of them uses water, and the other one does not, then comes out the decision, it relies on whether the location of your factory is available for water, if it is in North China, adopting the wet type will not be worthy.
In addition, from the analysis put forward above, the wet technology often needs lower rock hardness .Due to the long-term weathering (for example, when weathered rocks are used to make sand), we have to adopt wet one. Because this kind of rock has a lot of powder, so we'll washes it by sieving sand to improve the purity of the sand. But some of high hardness rocks (such as pebbles, quartz, granite, etc.) are necessary to use the dry method.
After learning about the differences between the dry and wet method, you can select the appropriate production process according to your circumstances, so the artificial sand production will be more and more efficient.
