Abstract: Barite becomes high value industrial powder after crushing grinding and classification. SBM PMD permanent magnet direct drive European mill has high transmission efficiency and stable operation and produces barite powder for oil drilling chemical and radiation shielding applications.
Barite is an important barium mineral raw material. Because of its high density moderate hardness and stable chemical properties it is widely used as weighting agent for oil drilling mud chemical filler radiation shielding material glass and ceramic industries. Quality indicators of barite powder mainly include fineness whiteness density and particle size distribution. The oil drilling industry sets high requirements for stability and fluidity of barite powder. Large fluctuations in powder fineness will directly affect mud density control and drilling efficiency.
Traditional barite grinding equipment has a long transmission chain with large energy loss. Mechanical wear and maintenance costs tend to increase during long term operation. To meet barite grinding requirements SBM has developed the PMD permanent magnet direct drive European mill. Full product details are available at
PMD permanent magnet direct drive European mill. The PMD mill adopts permanent magnet direct drive technology which reduces gearbox and intermediate transmission components. It has higher transmission efficiency lower mechanical loss stable operation and low vibration making it suitable for barite which requires stable finished particle size.
The grinding rollers and rings of the PMD mill are made of wear resistant materials to withstand long term grinding of barite. The hydraulic and spring structure can adjust grinding pressure according to material hardness keeping grinding efficiency stable. The classification system can flexibly adjust finished fineness to meet requirements of different industries. The system operates under negative pressure with pulse dust collectors resulting in low dust emissions and a clean workshop environment.
In actual projects SBM engineers first test the barite raw material to analyze hardness density whiteness moisture and feed size. Then they determine equipment model grinding pressure air volume and classifier speed. For oil drilling mud barite powder the particle size distribution and sedimentation stability are usually important. For chemical fillers and radiation shielding materials fineness whiteness and impurity content may receive more attention.
Barite project investment should consider not only the main unit price but also long term power consumption maintenance cost and product quality stability.
