Processing method for refining nonmetallic minerals
The invention belongs to the technical field of material processing, and discloses a nonmetallic mineral refining processing method, which comprises the following steps: crushing nonmetallic mineralsto obtain a nonmetallic blocky substance, drying the substance at room temperature, carrying out coarse grinding, carrying out secondary grinding on the coarse grinding particles, and carrying out ball milling in a ball mill; classifying and marking the powder with different particle sizes obtained by sieving after fine grinding, and determining the powder grade and the corresponding purpose; modifying the non-metallic mineral powder in a modification device and grinding the modified powder through a barrel type superfine vibration mill; calcining the modified powder, cooling the powder at room temperature, mixing the powder with a strong alkali solution, and carrying out water bath reaction; and adding excessive hydrochloric acid solution for suction filtration, and washing and drying theobtained filter cake to obtain the product. By finely grinding, grading, modifying and purifying the non-metallic minerals, fine processing of the non-metallic minerals can be realized, and the prepared superfine non-metallic minerals have the particle size of less than 200 nm, few impurities and better performance.
本发明属于材料加工技术领域，公开了一种非金属矿物精细化的加工方法，包括：将非金属矿物进行破碎得到非金属块状物质，室温下干燥后进行粗磨，将粗磨颗粒进行二次研磨，然后放入球磨机中球磨；对细磨后过筛得到的不同粒径的粉末进行划分，标注，确定粉末级别与对应用途；将非金属矿物粉末置于改性装置中进行改性，用筒式超细振动磨研磨，得到改性粉体；将改性粉体进行煅烧处理，室温下冷却后与强碱溶液混合，水浴反应；加入过量盐酸溶液进行抽滤，对得到的滤饼进行洗涤、干燥，即得。本发明通过对非金属矿物的细磨、分级、改性、提纯，能够实现非金属矿物的精细化加工，制得的超细非金属矿物的粒径小于200nm且杂质少，性能更优。
