River sand is used in the construction industry mainly for concrete production and cement-sand mortar production. River sand is obtained by dredging from river beds Origins : Malaysia,Vietnam,philippines
Chromite Sand Chrome Ore Price Grit/grain/sand Foundry chromite sand for foundry use as a highly fireproof sharpener for moulds and cores. Originally from South Africa. The sand is produced by crushing chrome ore and its washing in spiral concentrators, subsequent drying, dust cleaning, screening and sorting as per grain size.

Step1: chrome ore raw material is processed by water washing. Step2, drying raw materials to remove water; Step3, drying raw materials into the vibrating screen, screening out the size of the customer needs; Step4, the size of the sieve for magnetic separation, the purpose of iron and silicon removal. After magnetic separation, the chromium content reached more than 46% and the silicon content was less than 1%. Step5: package the finished product.
Foundry chromite sand is a natural process products of chromite through the broken screen classification, chrome ore, its main chemical composition of cr2o3, this kind of sand heated volume stability, high thermal conductivity, when in contact information with the molten metal, not only has good resistance to basic slag, not with ferric oxide and other chemical reactions, and itself has the characteristics of the solid phase sintering, can be a very good prevent the infiltration of molten metal, avoid to touch sand defects, suitable for all kinds of stainless steel, alloy steel and carbon steel gradually shape the original sand core and coating.
Chromite ore, also known as chromite ore, is a special sand for casting, is a natural spinel based on chromite, after crushing, grinding, screening into a specified size, suitable for molding (core) sand.

High quality Silica river sand. Screened once through a 7mm screen.
Garnet sand is made of garnet as raw material. It is a kind of iron-aluminum silicate with moderate hardness, high melting point and stable chemical properties. According to different products and structures, it presents different colors, such as dark red, brown red, pink and black. Widely used in optical industry, electronic industry, machinery industry, oil and gas and other industries.
