Features of dry
1. High sand productivity, up to 95%;
2. The sand making system adopts silicon dioxide or high aluminum material to avoid iron pollution;
3. High intensity magnetic separator is adopted to effectively remove iron substances;
4. Strict screening particle size control, long service life;
5. Reasonably set dust removal system to avoid production pollution.
The technical process
Quartz sand lumps enters crushing equipment to obtain sand with appropriate particle size,, and then fed into the system of sand rod mill or autogenous mill for grinding, then the fine grinding sand enters into the dry type magnetic separator to remove iron material , and then transported to the vibrating screen for screening and classifying, big size sand return sand making system to regrind. The sand under the screen of each layer is silica sand product with different particle size range.
