tics of different solid materials such as limestone, coke and iron ore. The objective of this paper is to develop an iron ore sintering bed model which takes the single par-ticle into consideration and incorporates more informa-tion on individual particles in terms of the entire iron ore sintering bed. 2. Modeling Approach 2.1.
Dec 11, 2016018332This work aims to assess the influence of particle size distributions of the individual components on the homogeneity of the infeed material by Discrete Element Model DEM Simulations. It can be concluded that modelling the PSD of the individual components is not required to model the tendency to segregate of the mixture of iron ore pellets ...
Sinter production uses a combination of limestone, iron ore, coke, and heat to prepare the iron ore for steel manufacturing. This application is typical of many in the ore processing industry and is very similar to steel making and coal power plants. These applications present a combination of challenges to silo level measurement.
