Silica sand, also known as quartz sand, is mainly composed of silica( SiO2), which is the main raw material for making glass.Silica sand has ordinary silica sand, refined silica sand and high purity silica sand. The content of silica in ordinary silica sand is between 90% and 99%, the content of iron oxide is less than 0.02%, the content of silica in refined silica sand is between 99% …
Sand mining is the extraction of sand, mainly through an open pit (or sand pit) but sometimes mined from beaches and inland dunes or dredged from ocean and river beds. Sand is often used in manufacturing, for example as an abrasive or in concrete.It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface.

Enclose machines. Large machines that produce a lot of chemical vapor, mist, or fumes, are safest when they are enclosed in a large, ventilated box. The box stays closed when the machine is working, and is opened to load, adjust, clean, and repair the machine. Exhaust ventilation removes vapors and fumes from the machine and the factory.
