A. Sa Simply stands for Sand as that is the abrasive medium that they used to determine the blasting standards on the 4 Rust Grades for ISO [link by ed. to spec at TechStreet. Remember Sand was the most widely used abrasive back in the days before the health risks of silicosis were identified. blasting sand grades Medium Grade Dakota Black coal slag abrasive is suitable for medium to heavy duty blasting such as removal of paint, rust and mill scale from structural steel and concrete surfaces.

This sandblasting sand is extra fine with 3060 grit. Each bag contains 100 lbs. of blasting sand, and it is designed to be used with a sandblaster. The extra fine blasting sand grades
Grade Anchor Pattern Applications# 1: : Heavy Rust, Tanks Ships, Barges and Concrete# 2: : General Purpose Medium to Heavy Rust or Paint# 3: : Medium Rust Barges, Ships and Nonsteel abrasives larger than 40 grit also use the direct pressure delivery blasting cabinets to pneumatically push the larger and heavier abrasives. Media Blast& Abrasive recommends the PowerPeen for these larger sizes. Siphon abrasive blasting cabinets, i. e. the N200 can also use steel type abrasives when the size is 80 grit and smaller. Normally a larger production gun is used to boost sand blasting and silicosis Workers engaged in sand blasting receive heavy exposure to free silica. Government studies show that even shortterm exposure to large amounts of free silica can cause acute silicosis, a disabling, nonreversible and sometimes even fatal lung disease. blasting sand grades A wide variety of blasting sand grades options are available to you, such as free samples, paid samples. There are 4, 093 blasting sand grades suppliers, mainly located in Asia.
