The application of barite powder in coating

Barite powder is an extender pigment which widely used in paint and coating, it and plays an important role in improving the thickness, wear resistance, water resistance, heat resistance, surface hardness and impact resistance of the coating film. HCQ Barite Grinding Plant is favored by many paint manufacturers for its high quality.

Barite powder fillers are mainly used in industrial primers and automotive intermediate coatings that require high film strength, high filling power and high chemical inertness, and are also used in topcoats that require higher gloss. The barite powder products used in paint coatings should not only have high purity, but also have fine particle size. Therefore, in addition to beneficiation and purification, ultrafine pulverization and surface modification are also required.

Barite has low Mohs hardness, high density, good brittleness and easy to be crushed. Therefore, it is usually dry process to process barite, and the commonly used Barite Grinding Plant includes Raymond mill, vertical mill, ring roller mill, etc.
