Barite (BaSO4) is a critical weighting agent in drilling mud formulations, requiring precise particle size distribution (typically 200-325 mesh) for optimal rheological properties. This article evaluates five advanced grinding technologies that deliver high-purity barite powders with superior API specifications.
Parameter | API 13A Standard | Premium Grade |
---|---|---|
Specific Gravity | ≥4.20 g/cm³ | ≥4.30 g/cm³ |
Particle Size (D50) | 6-25 μm | 8-15 μm |
Soluble Alkalis | ≤250 mg/kg | ≤100 mg/kg |
For operations demanding ultra-fine barite powders (D97≤5μm), our SCM Ultrafine Mill series delivers unmatched precision with vertical turbine classification technology. The patented three-layer grinding mechanism achieves:
Model | Capacity (t/h) | Power (kW) | Footprint (m²) |
---|---|---|---|
SCM800 | 0.5-4.5 | 75 | 15 |
SCM1680 | 5.0-25 | 315 | 45 |
When processing mid-range barite (30-325 mesh), the MTW Series combines European grinding technology with innovative wear-resistant components:
For large-scale barite processing plants (15-250 t/h), LUM mills offer:
This cost-effective solution features:
Traditional wet grinding solution for:
Our flagship SCM1680 model demonstrates exceptional performance in API-grade barite production:
