Silica sand provides the essential Silicon Dioxide (SiO2) required for glass formulation, which makes silica the primary component in all types of standard and specialty glass. Though the production of glass requires a variety of different commodities, silica represents over 70% of its final weight.
A mined silica sand site. Figure 4. The ravenous topography resulted from large scale open cast mining. sand falls by gravity to the bottom. After washing, the sand is then sent to a surge pile where water adhering to the sand particles infiltrates back into the ground. From the surge pile the sand is sent to the dryer and screening
When choosing a silica sand washing plant manufacturer, it is best to conduct field investigation on the manufacturer, investigate the scale and environment of the manufacturers workshop, fully understand the production process and supporting facilities of the equipment, and also test the silica sand processing equipments. 4.

moulds and cores in refractory materials such as silica sand. The main properties of silica sand that are essentially related to the traditional moulding and core-making processes are size , and refractoriness. The silica sand used for 3DP must be appropriately selected also for the layerbased manufacturing process involved in 3DP.
