The barite grinding process is generally: crushing → screening and classification → wind selection.After the ore is crushed, the barite is basically formed into a flaky shape, and the gangue mineral feldspar, quartz and the like are in the form of massive particles.

Accordingly, the multi-level grading is used to pre-divide the selected materials into narrower granules, and according to the difference in the levitation speed in the airflow, special air-conditioning equipment is used for sorting. The wind selection method is applicable to areas where water is scarce and has been used for actual production.
