METHOD FOR FINELY PROCESSING NONMETALLIC MINERAL
The present disclosure discloses a method for finely processing a nonmetallic material, including: crushing a nonmetallic mineral to obtain a nonmetallic block, drying at ambient temperature, coarsely grinding the dried nonmetallic block to obtain coarsely ground particles, subjecting the coarsely ground particles to a second grinding, and then ball milling in a ball mill, drying and sieving to obtain a powder with various particle sizes; classifying and marking the powder to determine the grade and corresponding use of the powder; modifying the nonmetallic mineral powder in a modification device, grinding by a drum ultra-fine vibration mill to obtain a modified powder; calcining the modified powder, then cooling at ambient temperature, mixing with a strong alkali solution to react in a water bath; adding an excessive hydrochloric acid solution, and filtering, washing and drying the resulting filter cake to obtain a product.
