Garnet—An Essential Industrial Mineral and January's
quently, garnet is an excellent abrasive for applications such as sand- or air-blasting, water-jet cutting, and sandpaper. Garnet is now used for some blast-cleaning applications that previously used common sand. Common sand contains crystalline silica (SiO 2) that in the form of dust produced during blasting can cause lung damage if inhaled.
Garnet sand is a good abrasive, and a common replacement for silica sand in sand blasting. Alluvial garnet grains which are rounder are more suitable for such blasting treatments. Mixed with very high pressure water, garnet is used to cut steel and other materials in water jets. For water jet cutting, garnet extracted from hard rock is suitable
Difference Between Abrasive Jet Machining and Sand
Abrasive Jet Machining Sand Blasting; Several abrasive particles, such as silicon carbide (SiC), alumina (Al 2 O 3), glass beads, etc. are used to remove material by impact erosion. Only silica sand grains (SiO 2) are used to remove material by impact erosion. Size of the abrasive particles and its flow rate are more or less uniform.
Unlike sand or silica, which were previously used in water and sand blasting, garnet doesn't break down during these processes, so can be recycled to be used over and over. Other Industrial Uses. Garnet particles are mixed with water and fired in a high-speed jet in a process known as water jet cutting. Water jet cutting slices through metal and even granite with precision and
Black Beauty Grit — Also known as black diamond and black blast, it's the best alternative to silica sand. Contains less than 0.1% free silica. It's inert and moisture free. Not recommended for removing paint from aluminum and plastic.

Jet-Mag is silica-free replacement for silica sand, recycled crushed glass, and natural olivine. While Jet-Mag does produce a dust it has been classified by OSHA/NIOSH as only "nuisance" dust. Due to it's translucent nature visibility is substantially improved when compared to traditional hard abrasives.

Abrasive Garnet. Garnet is a mineral abrasive produced from naturally occurring almandite garnet. It is produced by processing beach sand and grading to exact specifications. Due to its low free silica, Garnet abrasive is widely used in sand/grit blasting and now widely popular for waterjet cutting.
The control of substances hazardous to health regulations
Nov 21, 2021 · Silica sand and 'silica-free' sand 5 The use of allegedly 'silica-free' substitutes has frequently raised the question of what qualifies as 'silica-free'. In considering this, it should be appreciated that crystalline silica is a very commonly occurring substance in both the natural (rocks and soil) and artificial (mainly construction materials
Oct 14, 2021 · Garnet abrasive is most generally used as a high-performance blast media, for the cleaning of aluminum and fiberglass structures. Because it is an inert, non-toxic, naturally occurring mineral, garnet abrasive is also used in places where water contamination is a concern, such as dry docks, bridges, and harbors.

Risks of Silica Sand Silica sand is a very abrasive material making it effective at quickly profiling a product surface but the problem is that when it hits a products surface it fractures into very tiny particles. These tiny particles are so small that even proper sandblasting respirators are not necessarily sufficient enough to prevent
