Grade Division of Brown Corundum

- Nov 27, 2018-

The main component of Brown corundum is alumina, the classification is also used to distinguish the aluminum content, the lower the aluminum content, the lower the hardness. Product granularity in accordance with international standards and national standards of production, according to user requirements of granularity processing. The generic granularity number is f4~f320, and its chemical composition varies depending on the size of the granularity. The outstanding feature is that the crystal size is small impact resistance, due to the use of self-grinding machine processing crushing, particles are mostly spherical particles, surface dry clean, easy to combine with the binder.
