In the industrial usage, the silica sand should be processed. Based on years' abundant production experience and high technology, SBM has produced the various machines used for mining silica sand, such as crushing machine, grinding equipment and the sand washing machine etc. Here is the detailed information of silica sand mining machines.
There are various machines used in silica sand mining process. The whole silica sand mining process generally includes the following steps: crushing, grinding and separation. In the crushing process, the raw materials firstly sent into the jaw crusher for the primary crushing, if necessary, the crushed materials will enter in the impact crusher or cone crusher for further crushing. Then the minerals enter into the ball mill or grinding mill to be grinded. Next is the separation process. The separation process can be divided into flotation separation, gravity separation and magnetic separation.
Silica sand crushing equipment often has jaw crusher for the first crushing process, cone crusher, impact crusher for the secondary crushing, and VSI crusher for hard materials crushing.
Ball mill is an efficient tool for grinding the silica sand to discharging part, gyre part, transmission (decelerator, small transmission gear, generator electrical control ) and so on. The hollow axis adopts the cast steel and the lining can replace the rotating big gear processes in the way of casting rolling gear. The barrel body is well and bears wearable scale board. This machine run steadily and works reliably materials into fine powder. The ball mill is used grind many kinds silica sand, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.
In silica sand, various magnetic minerals are involved in it. We can use the magnetic separator to eliminate the undesired materials.
