Chromite separation GUT Giesserei Umwelt …
In comparison with silica sand chromite sand features a higher temperature resistance and a better thermal conductivity. These attributes predestinate this kind of sand especially for no-bake moulding-lines with high material accumulation and for casting materials with high casting temperatures as they are for example in steel casting. On the one hand chromite sand guarantees a high quality for several …

What Is Silica Sand & How Is It Different From …
Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz – a chemically inert and relatively hard mineral. SiO2 grades at a 7 out of 10 on Mohs hardness scale, making it ideal for use as filtration media and abrasive ...
