Natural white pebbles
White pebbles. Stone as a kind of natural stone, from experienced million years ago after the crustal movement produced by the ancient riverbed uplift sand mountains, experiencing the flash floods hit, handling continuous extrusion, friction. In the tens of thousands of years of vicissitudes of evolution, they have water flushing wave motion, gravel collision friction lost irregular edges, and sediment is buried deep in the ground silent millions of years.Cobblestone main chemical composition is SiO2, followed by small amounts of iron and manganese trace, copper, aluminum, magnesium and other elements and compounds. They have different colors, such as red to blue for iron, copper, purple for manganese yellow translucent for silica gel stone, jade color with green mineral and so on; as a result of these pigment ions into the silica hydrothermal type and content, thus showing the depth of shade, the changing color, so that the pebbles show black, white, yellow, red, green, green color. Commonly known as the supporting layer media or the media, divided ( NATURAL ) ( machining ) quartz pebbles and gravel two. Natural stone is a natural river mining, washing, screening and into, approximately spherical, and smooth surface, color is pure white and mottled two. Gravel for quartz ore crushing and refined processing. A variety of water purification filter technology is an indispensable supporting layer filter.Use:Widely used in water plant, mechanical filters, ion exchange water treatment such as supporting layer.
