Magnesium Oxide for Millstone

Magnesium oxide for millstone is a main application. High-activity MgO, low CaO, and reasonable LOI make all these items suitable for millstone production. The main raw materials are magnesium oxide and magnesium chloride. After reaction to produce A principal application of MOC cement-magnesium oxychloride cement-(add caustic calcined magnesia to MgCl2 solutions) is in the manufacture of abrasive stones and grinding wheels. Due to its very high bonding strength, MOC cement is largely used in the manufacture of grinding and polishing stones. In this application, MOC cement is used to bond SiC grains.

The main end-users of magnesium oxide for millstone are the marble, granite, and mosaic processing industries. Despite the strong competition with diamond discs and other resin-bonded tools, an increased demand for Magnesia cement-bonded grinding and polishing stones has been witnessed during the last few years, thanks to the development of the "gres porcelanato" type of ceramic tiles. Another interesting and developing application is in the manufacture of special millstones for rice peeling, where the ecological properties of Magnesia cement-bonded grinding and polishing stones are highly appreciated. Magnesium oxide can also be used as magnesium fertilizer. As we know, magnesium is a required element in plant photosynthesis.

If Mg is deficient, the shortage of chlorophyll results in poor and stunted plant growth. Magnesium also helps to activate specific enzyme systems. Enzymes are complex substances that build, modify, or break down compounds as part of a plant's normal metabolism.
