Quartz stone can be widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, rubber, abrasive and other industries after processing. It is an important industrial mineral raw materials. As it has strong anti-acid medium erosion ability, we uauallly use it to make acid-resistant concrete and acid mortar.
Quartz sand production process is: quartz stone raw materials – jaw crusher – small stone – impact crusher – sand making machine – mill – sedimentation basin – dryer – dry sand – vibrating screen – iron removal – finished product – storage. Dry method of quartz sand has ordinary and refined type; wet method is also divided into the two kinds. Compared with dry method, the wet process has less iron and water washed away impurities, iron content and impurities are less than dry quartz powder.
