Description

[0003] Drying is one of the important steps in the processing of quartz powder. Since quartz sand absorbs a large amount of water during mining, crushing, grinding and transportation, and quartz powder itself has a certain hygroscopicity, in order to ensure the quality of quartz powder and improve its performance in industrial applications, it is usually necessary to use drying equipment to dry quartz powder to reduce the water content in quartz powder.
