The manufacturer of HCMilling(Guilin Hongcheng) quartz sand grinding mill machine has learned that relevant Chinese institutions predict that under the background of continuous growth in downstream photovoltaic demand, the supply and demand of high-purity quartz sand will basically remain tight. In 2025, the demand for high-purity quartz sand is expected to reach 2.7 times that of 2022, and the price of high-purity quartz sand will further soar.

Due to its stable structure, physical and chemical properties, quartz is characterized by high temperature resistance, low coefficient of thermal expansion, high insulation, and corrosion resistance. It is widely used in various industries such as construction, communication, photovoltaic, optics, aviation, semiconductor, etc. According to the different purity, we can further classify high purity quartz into low end (3N), middle end (4N), and high end (4N8 and above). The specific application fields of quartz with different purity vary. Ordinary quartz below 3N is used to manufacture glass, refractory materials, etc. Grade 3N is used for manufacturing silicic acid based chemical materials, Grade 4N is used for electronic packaging and other fields, Grade 4N8 is used for photovoltaic and communication, and Grade 5N is used for semiconductors and chips. Due to its excellent characteristics and scarcity of raw materials, the price of high purity quartz sand has been at a high level, and there is still room for growth.

High purity quartz sand is pretreated with high-grade quartz stone (generally using mechanical crushing, electric crushing, optical separation, ultrasonic crushing, and thermal shock crushing), physical treatment (mainly including grinding, color separation, magnetic separation, and flotation), and chemical treatment (mainly including acid washing, leaching, and thermal chlorination). One of the important steps is to grind it into quartz powder with a suitable particle size through a quartz sand grinder, and then carry out further processing.

HCMilling(Guilin Hongcheng) provides high-quality quartz sand grinding mill machines to assist the development of the photovoltaic industry. Quartz stone can be processed efficiently and in large batches to prepare high-purity quartz sand, creating enormous value.
