the gujarat bentonite grinding project india
in the kutch district of gujarat in western india a region famous for its white desert and challenging climate a major industrial project is processing locally abundant bentonite clay for the global oil and gas industry. this is the gujarat bentonite grinding project which features a large-scale raymond mill stone powder grinding mill with a formidable capacity of 15 tons per hour. bentonite is a unique clay that swells dramatically when wet making it an essential component of drilling fluids or drilling mud used in oil and gas exploration worldwide.
the raw bentonite from local mines contains significant moisture and requires processing to achieve the precise specifications demanded by international oil companies. the grinding mill reduces the dried bentonite to a fine powder with a target fineness of 200 microns or 75 mesh. this specific particle size ensures rapid hydration when mixed with water creating a viscous fluid that lubricates drill bits carries rock cuttings to the surface and seals the wellbore against collapse.
the project was developed by a major indian minerals company to supply both the domestic drilling market and export customers in the middle east and southeast asia. the challenge in this project was the extremely hygroscopic nature of bentonite which tends to absorb moisture from the air and clog grinding equipment. the engineers solved this by designing a completely closed-loop system with dehumidified air and a specialized mill discharge arrangement that prevents material buildup.
the 15 tons per hour output from this stone powder grinding mill ensures a consistent high-quality product that meets the stringent american petroleum institute specifications for drilling-grade bentonite. this project has solidified indias position as a leading supplier of this critical industrial mineral to the global energy sector.
