ultra fine barite particle size in Oman
Application of Ultra Fine Ilmenite Powder as Drilling
Since ultra-fine ilmenite has narrow particle size distribution (D50≈5 μm), in drilling fluids of the same density, drilling fluid weighted with ultra-fine ilmenite has higher HTHP filtration rate.

4. How do you adjust particle size in your mill? Particle size is adjusted primarily by a change in feed rate. When the rate is reduced, finer particles result because there is more energy available per particle to accelerate the particles and the entire fluid mass. Collisions become more violent and pressure gradients become larger.
