Sand is washed ashore with waves and blown inland forming sand dunes. There are dramatic seasonal changes in sand movement: high-energy winter storm waves pull sand offshore; lower, gentle summer waves carry sand onto the beach. Sand flows into submarine canyons where it is stays for millennia (barring human intervention).

The silica sand processing plant adopts the following technical scheme: Step 1: Take quartz gravel and crush it into pieces. Step 2: Put quartz gravel fragments into the autogenous mill, and add water to the autogenous grinding machine according to the mass ratio of quartz gravel to water of 1:035-0.5 for autogrinding.

In recent years, the purification process of quartz sand at home and abroad is mainly carried out in the following aspects. 1. Water washing, grading desliming. The grade of SiO2 in quartz sand decreases with the fineness of the grain size of quartz, and the grade of impurity minerals such as iron and aluminum is just the opposite.

Damp sand sticks together because water forms little grain-to-grain bridges. Surface tension--the same force that lets some insects walk on the surface of a pond--acts like rubberbands between the grains. Adding water to damp sand fills spaces between the grains. The bridges vanish and the sand begins to flow more easily.
