Investigation on Properties of Bentonite Type in Cold Bonded Pelletization of Flue Dust

Abstract:

In the integrated steel mills fabrication processes, the by-product of flue dust and electrostatic precipitator dust were found to be rich with large amounts of iron and carbon content and it could be recycled as a raw material for blast furnaces. In this study, we use the “Cold-bonded Pellet; CBP” technique to prepare the recycling samples for subsequent processing. Therefore, this study investigated under a fixed amount of bentonite added, the choice of different types of bentonite on the powder granulation performance and strength of particle duration effects, bentonite used as a basis for adjustment. The results showed that Bentonite samples of the granulation efficiency increase, relative to its yield and the rate of sticky increase. In general, CBP particle compressive strength increased, duration have increased, and found that curing condition B are large than the A method. In addition, by particle size analysis results show that, bentonite average particle size of 11-12μm have better compressive strength. Comprehensive assessment of granulation and mechanical properties, of which A label in four Bentonite can be preferred.
