River sand and water washed sand are sand needed in China's infrastructure construction. With the increasingly strict monitoring of river sand mining, river sand mining has been strictly prohibited in some areas, and water washed machine-made sand is more and more widely used. Is there any difference between river sand and water washed sand? Tangshan Shiny answers for you.

River sand comes from the beach, and its resources are relatively rich. However, with the over exploitation in recent years, it has shown a trend of gradual scarcity. The characteristics of river sand are less soil content and impurity quality. River sand is mainly beach sedimentary sand, with grayish white or grayish yellow color, which is composed of fine sand, medium coarse sand, coarse sand, gravel layer and gravel layer. The occurrence of river sand is towards the riverbed, and the surface layer is inclined from the bank to the riverbed, inclined from upstream to downstream. River sand has the characteristics of hard texture and clear color. It is a good building material.

Washed sand is the raw sand made of natural silica sand by washing and grading, and the mud content is smaller than that of river sand. Water washing sand is that natural sand is sent to the sand washing machine for cleaning, and the stone powder, soil and fine sand and stone particles in the sand and stone are cleaned and filtered. The purpose of controlling the particle size of finished sand and stone can be achieved by controlling the mesh number of washing screen, so that the content of fine sand particles and stone powder can be controlled within a certain proportion, so as to improve the overall sand and stone quality. The sand and stone raw materials can pass the water washing process, The granularity of finished products can be regulated efficiently, and the granularity of finished products can be combined and separated into various specifications of sand according to the needs of users.
