Shot blasting machine are widely used in blast cleaning the cement and rust of the used scaffoldings, this kind of application on scaffoldings greatly increase the pre-treatment speed and effect. According to ANSI A10.8-2001 Safety Requirements, there is no better way to dealing with the used scaffoldings to get them safely engaged in their service again. People used to acid pickling and hot-dipped galvanized the used scaffoldings, but it is very hard to dealing with the hard cement on the surface by pickling, and along with the whole world environmental awareness increases, the old technology certainly will be instead by new and environment-friendly processing method. So here comes the shot blasting machine technology. It has been widely used in concrete surface waterproof, all steel material rust removal and descaling, stone or concrete pavers texturing, etc.
