Sandblasting Grit Size Conversion Chart | Media Blast
Media Blast & Abrasive recommends the PowerPeen for these larger sizes. Siphon abrasive blasting cabinets , i.e. the N-200 , can also use steel type abrasives when the size is 80 grit and smaller. Normally a larger production gun is used to boost the siphon-feed of these larger/heavier abrasives.
