garnet abrasive

We are manufacturer and exporter of natural garnet in China, and our mine together with factory is situated in middle of Inner Mongolia, where the deposits of mine is plentiful.

Our natural garnet is a kind of hard-rock garnet, which is used widely in water filtration, sandblasting, rubber and plastics, deep oil welling, waterjet-cutting, abrasive polishing and some other special application. The deposit is an almandite which contain garnet from 60%-75%. Due to the garnet is processed from big rock lump, we can process the garnet with the size ranging from 4 mesh to 200 mesh, this is our advantage. We can meet our customers' requirements both in quality and size.
