Applications of RHEWUM Screening Machines
Silica sand
is a sand mostly consisting of silicon dioxide (SiO2).
After washing and fine screening silica sand is used in glass industry for the production of flat and round glass and in the foundry industry for mould making. Sand containing less than 0.023% iron is suitable for the production of translucent (white) glass. For this mostly very fine silica sand of a particle size between 0.1 and 0.4 mm and a humidity of less than 5% is used.
Besides this silica sand is used for the production of ceramics and fibre glass, in the chemical industry and in abrasives, as moulding sand as well as nonplastic material resp. filler.
In ceramic industry silica sand as nonplastic material reduces the drying loss but at the same time downgrades the ductility of the ceramics and it becomes brittle. Mostly silica sand is used as very fine sand with a high purity to avoid unwanted discolourings.
Fibre glass is used as glass fibre cable for data transmission and for the production of glass fibre reinforced plastics by spinning fine fibres with a defined diameter.
