Effects of Pellet Basicity on the Simulated Deposit Formation in Coal ...
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 to 41.5% as the pellet ...
