A review on properties of abrasive grits and grit selection
by Barbara S. Linke
International Journal of Abrasive Technology (IJAT), Vol. 7, No. 1, 2015

Abstract: Although abrasive machining is among the oldest manufacturing principles, it is still essential for today's industry. Abrasive tool quality is significantly affected by the quality of the contained abrasive grits. This paper gives an overview on the most important grit properties for grinding tools with regard to tool performance and manufacture. These properties include grit size, shape, and toughness. Relevant techniques for grit sorting and analysis (sieving, sedimentation, shape sorting, friability testing, etc.) are presented and compared with regard to the controlled grit properties. Grit quality remains an important criterion for tool performance. More transparency in grit sorting techniques and quality indicators for abrasive grits can help many stakeholders: grit producers, tool manufacturers, and tool users. Moreover, recycling of used grinding tools might become a future market.
