Granite Cutting Media Angular Sand Blasting Bearing Steel Grit for Granite Mill

Granite Cutting Media Angular Sand Blasting Bearing Steel Grit for Granite Mill

bearing steel grit is our wholly new steel abrasive media in our factory, bearing steel grit is made with bearing steel materials, a high – strength steel materials, so this type steel grit is with good hardness and longer fatigue life than cast steel grit. Similar with cast steel grit, GP/GL/GH types are all available for bearing steel grit, angular steel grit, types available from G10 – G120. bearing steel grit, angular steel grit mainly used for cutting hard stones, like granite cutting, assembled in large multi-blade frames to cut the raw granite into thin slices. Also angular steel grit used for surface treatment of steel plate in shipbuilding, higher efficiency during treatment than cast steel grit.
