Sandblast Media Review Abrasive Black Beauty Types And What You Should Know About Silica Dust Safety Services
Silica sand is banned and it therefore cannot be used for sandblasting purposes in some countri The media also causes corrosion on the sides of a blast gun which leads to faster wearing and tearing of machineryThe use of silica for abrasive blasting is also not economical since the media can only be used once or twiceWhat are the Damaging Effects of Silica Dust Silica dust is an extremely common and potentially hazardous mineral compound found throughout numerous industries and applications across the globe It exists in nature primarily as quartz although in many areas it is a major component in sand
