1. Introduction
< p>The core components of the QF-5 and QF-300 air classifiers designed in this project have high precision and have been proven through testing and production to have reliable operation, low noise, small vibration, and easy maintenance and repair. The grading system has advanced technology, reasonable process design, compact equipment configuration, and flexible adjustment of classification particle size. According to user requirements, the fine powder (0~150μm) can be divided into several narrow-grained products of different specifications (between 3~150μm). Adjust the grading points arbitrarily). This classification process is used in conjunction with Raymond mill and can produce products of various particle sizes with a pass rate of more than 90%. It is conducive to the rational use of resources and increased corporate profits. It has opened up a new technical route for the deep processing of non-metallic mineral resources in my country.2. Promotion and application
The situation is the same as the complete set of impact ultra-fine grinder equipment.
3. Appraisal, awards, and patent status
The research started and ended from December 1991 to 1996. The results were evaluated in August 1996. Won the third prize for scientific and technological progress in the building materials industry in 1996.
