A quartz crushing and screening plant is a facility used to process quartz ore. Quartz is an important mineral used in many industries due to its high hardness and chemical resistance. In these plants, quartz ore is first subjected to a crushing process. Crushing is done to reduce the size of the ore and make it easier to process. Then, a screening process is used to separate quartz pieces of different sizes. These processes are necessary for quartz to be used in the glass, ceramics, electronics, and construction industries.
