Pelletizing Plants | BOLLFILTER
Pelletizing is the process through which iron ore fines are transformed into an agglomerated form called "iron ore pellets" suitable for use in an iron-making furnace at a steel mill, such as a blast furnace or electric arc furnace. In its end product form, a typical iron ore pellet is roughly spherical in shape, measuring from 6 mm to 16 ...

Effects of Pellet Basicity on the Simulated Deposit Formation in …
Deposit formation in the coal-fired rotary kiln is frequently found in the production of fluxed iron ore pellets by the grate-kiln process and affects normal production. In this paper, the effects of pellet basicity (CaO/SiO2 mass ratio) on the simulated deposit formation were investigated. The results show that the porosity of deposits samples increases from 30.8 …
