Jun 22, 2017 The physical and chemical properties such as particle size, montmorillonite content, swelling degree, water absorption, and blue absorption of A, B, and C bentonites were studied under laboratory conditions. The effects of adding different quality and different proportion of bentonite on falling strength, compression strength, and shock temperature of green pellet were investigated. In the present pelletizing apparatus, the induration of iron ore concentrate pellets is achieved in a tunnel furnace heated by plasma torches, wherein the generation of CO2 by the conventional iron ore pelletizing processes is reduced by using electricity powered plasma torches instead of burning natural gas, heavy oil or pulverized coal in burners, thereby reducing considerably industrial ...

Jun 11, 2019 Sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials. Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption. During the iron ore sintering process in iron and steel manufacturing , an online analyzer can be used to determine the elemental composition of the bulk raw materials in sinter feed. consists of a cellular mass of ore bonded in a slag matrix. The sinter mix, besides the ore fines, usually contains other materials like flue dust, return fines, limestone and/or dolomite etc., in order to control the properties of the product as well as to utilize industrial waste. Return sinter fines having lower fusion temperature than the raw mix serve as seeds for initiation of the sintering process.
