grinding grit of carbon black sri lanka

Grit size is the abrasive grade of a material, and what the user chooses depends on the application. Grit sizes range from coarser, to medium, to finer. A higher grit number indicates a smaller abrasive grain and, thus, a finer abrasive product. Using a flap disc with a coarser grit size is ideal for heavy stock removal or grinding applications.
