In the ground under high pressure, the need to increase the proportion of mud, barite powder added to the slurry is an effective measure to increase the proportion of mud.
oil drilling Barite (Barium Sulfate) 4.2 used in drilling mud to do the general fineness of 325 or more to achieve, such as the fineness of barite precipitation is easy enough. Requirements with the barite drilling mud weight is greater than 4.2, BaSO4 content of not less than 95%, less than 1% of soluble salts. 


1. As a weighting agent for drilling fluids in oil and gas exploration.
2. Used in the car, electronics, TV screen, rubber, and glass ceramics and paint industry.
