Garnet is derived from mined Almandine mineral deposits.
Almandine is the heaviest and hardest of the all
the garnet types in the garnet family group, resulting
in an ideal abrasive grain for blasting applications.
Once extracted, the raw material is processed to remove
chlorides and sulfates, magnetically screened to remove
ferrous particulate, and finally screened to the desired
Being an inert, non-toxic mineral, containing less
than 0.1% free silica, EnviroGrit™ is an enviro nmentally
safe, user friendly alternative, to silica sand and
other expendable abrasive.
EnviroGrit™ Garnet particles are sub-angular in shape
resulting in extremely fast cutting rates and low abrasive consumption.
high specific gravity of the abrasive grains, and the
low breakdown rate, results in significantly
reduced dust levels, thus ensuring good operator visibility,
and less risk to personnel or environmental contamination
in surrounding areas. The low consumption rate and the
recyclability, up to 5 times, of the abrasive, also ensures
the volume of waste generated for disposal is minimised.
Being a naturally occurring mineral EnviroGrit™, is also
a non-pollutant to the environment.
Blast cleaning production rates using EnviroGrit™ are
greatly increased when compared to other expendable abrasives.
This factor, along with the reduced amount of abrasive
consumed, can lead to significant cost savings per square
meter blasted, and often results in EnviroGrit™ Garnet
being the most cost effective abrasive available for
the blasting project.
EnviroGrit™ is processed under stringent quality control
regulations to ensure the size and distribution of particles
in the abrasive mix is maintained at the correct proportion.
This ensures an ac curate, consistent surface profile
is maintained. A surface cleanliness of Class Sa3, even
on heavily pitted and corroded steel, is easily achievable
with EnviroGrit™, and abrasive embedment into the surface
Containing minimal ferrous particles EnviroGrit™ can
be utilised to blast corrosion resistant steels and non-ferrous
products without the risk of ferrous contamination to
EnviroGrit™ is also utilised as a cutting media in water
jet cutting, and as a filtration media.
