Dust pollution is the main hazard of sintering production in the metallurgical industry. The economic loss caused by this is quite serious. Countries and enterprises invested a lot of money for this purpose, resulting in greater economic benefits. According to the capital invested by Ansteel Sinter Plant over the 10-year period from 1989 to 1998, the dust-proofing facilities were evaluated for dust-proofing projects with an investment-benefit ratio of 1: 2 2 3. The results confirmed that the plant was dust-proof The economic and social benefits of the project are very significant
