  • Patent number: 11518711
    Abstract: A method for producing a dust-reducing and dust-absorbing material from a nonmetallic mineral and a raw material from a cement plant. The method includes calcining the limestone block, to obtain quicklime; cooling the quicklime at ambient temperature, drying and pulverizing the quicklime, to obtain a first powder essentially consisting of a quicklime powder and a calcium carbonate powder; fully drying and grinding a nonmetallic mineral, to obtain a nonmetallic mineral powder; mixing the first powder and the nonmetallic mineral powder, stirring to be uniform, to obtain a mixture, and ball milling the mixture, to obtain a nano-powder; adding a dust-absorbing material to the nano-powder, adding water and mixing, and pouring the resulting mixture into a mold, and stoving; and air drying the resulting mixture, to obtain a cavernous dust-reducing and dust-absorbing material.

  • Publication number: 20210380490
    Abstract: 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.
