A naturally occurring mineral composed of a solid solution of magnesium ortho silicate, (forsterite, Mg2SiO4) and iron ortho silicate (fayalite, Fe2SiO4). Olivine crystals are angular with sharp edges. the product is hard, dense and heavy. It has good insulating values due to a low heat conductivity. It is essentially hydration-free. It has a high refractoriness level ~1760 deg. C. It is essentially inert and has high chemical and mineralogical stability.
Olivine Sand Making Plant Turkey
Olivine improves the activation of Bentonite clay in green sand systems to maximize bond performance and efficiently produces chemically bonded cores, mold and shell sands with compatible resin systems.Produced from high purity ore, Olivine grades are used for the most demanding aluminum casting application. Their rapid heat dissipation reduced the resonance of molten aluminum against the sand mold to promote the development of finer metallic grain structures for smoother cast finish.
Olivine’s low rate of thermal expansion greatly reduces the incidence of grain movement or fracture to virtually eliminate wall movement or centerline shrinkage in both ferrous and non-ferrous castings. Reduced burn-in penetration defects and lower cleaning costs are achieved with Olivine whether used alone or blended with silica sands in lost foam applications.
Rutile Sand Washing Plant Manufacturer China
Rutile Sand Washing Plant Supplier. Our Rutile Sand Washing Plants have exported to many countries for their mining industry such as , Indonesia, Vietnam , Iran, India, Chile, Venezuela, Libya, Angola, Kenya, South Africa, Pakistan , Yeman, Eygpt, Nigeria, Tajikistan , Saudi Arabia , Zimbabwe, Dubai.Rutile is a common accessory mineral in high-temperature and high-pressure metamorphic rocks and in igneous rocks. Rutile is the preferred polymorph of TiO2 in such environments because it has the lowest molecular volume of the three polymorphs; it is thus the primary titanium bearing phase in most high pressure metamorphic rocks.Finely powdered rutile is a brilliant white pigment and is used in paints, plastics, paper, foods, and other applications that call for a bright white color. Titanium dioxide pigment is the single greatest use of titanium worldwide. Nanoscale particles of rutile are transparent to visible light but are highly effective in the absorption of ultraviolet radiation.
