Description

Technical Field

[0001] This utility model relates to the field of barite processing technology, and in particular to an integrated mechanical device for negative pressure circulating grinding and grading of barite. Background Technology

[0002] Barite (barium sulfate) is an important non-metallic mineral raw material. Its ultrafine powder, after grinding, is widely used in high-end fields such as coatings, inks, plastics, rubber, chemicals, radiation-proof concrete, and oil and gas drilling mud weighting agents due to its excellent properties such as high density, high whiteness, chemical inertness, and X-ray absorption. With the technological upgrading of downstream industries, increasingly higher requirements are being placed on the particle size distribution, particle morphology, purity, and processing efficiency of barite powder. Traditional grinding equipment such as ball mills and Raymond mills, and classification equipment such as turbine classifiers, are independent units. After grinding, the material needs to pass through intermediate conveying equipment such as elevators, conveying screws, and silo pumps before entering the classifier. This layout not only requires a large footprint and high infrastructure costs, but also easily leads to blockage, dust generation, and secondary pollution during material transport. Therefore, we designed an integrated mechanical device for negative pressure circulating grinding and classification of barite. Utility Model Content
