Barite (BaSO4) is a critical weighting agent in oil well drilling fluids, requiring precise particle size distribution (325-2500 mesh) to ensure mud density control and rheological stability. This article explores advanced grinding technologies for producing API-grade barite powder, with a focus on high-efficiency milling solutions.
| Parameter | API 13A Standard | Premium Grade |
|---|---|---|
| Specific Gravity | ≥4.20 g/cm³ | ≥4.30 g/cm³ |
| Residue on 325 Mesh | ≤3.0% | ≤1.5% |
| Water Soluble Alkali | ≤250 mg/kg | ≤150 mg/kg |
