Differences between garnet sand and brown fused alumina :
Garnet sand, is a natural abrasive, which is directly mined from mines. The raw materials are screened and classified into mine ore without artificial smelting. Its processing time is short, the efficiency is high, and the price is low. It can make up for the short lifespan. insufficient. It is widely used in sandblasting and rust removal, waterjet cutting, filter media, grinding, wear-resistant floors, etc. It is roughly the same function as brown fused alumina. In appearance, it is similar to brown fused alumina.
The differences are summarized as follows:
1. Garnet sand has not been artificially smelted, so its service life is shorter than that of brown fused alumina, but the price is also lower than that of brown fused alumina .
2. The chemical composition of garnet sand is more complex than brown fused alumina, and it mainly contains SiO2, Al2O3, Fe2O3, TiO2, MgO, FeO, CaO, MnO, etc.; the main component of brown fused alumina is Al2O3, and the content is higher.
3. The hardness of garnet sand is slightly lower than that of brown fused alumina. Its Mohs hardness is 7.5~8.0, and that of brown fused alumina is above 9.0.
4. Brown fused alumina are more widely used than garnet sand, especially in refractory and ceramic industries other than sandblasting, polishing and grinding.
