Online Monitoring of Iron Ore Pellet Size Distribution Using

Most of the pellet plants in steel industries use human supervision for pellet growth monitoring. In this paper, a camera-based pellet size distribution monitoring method is 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 Effects of Pellet Basicity on the Simulated Deposit Formation

Optimization of Pellet Plant Straight Grate Induration

Indian iron ores are suffering from high amounts of alumina and loss on ignition (LOI), which are deleterious constituents in both the pelletizing as well as iron making processes. Iron ore fines utilized in pellet making consist of alumina in the range of 3.20–3.35% and LOI in the range of 3.50–3.70%. Detailed palletization studies have In an iron ore pelletization plant, pellets are produced inside a rotating disc pelletizer. Online pellet size distribution is an important performance indicator of the pelletization process. Image processing-based system is an effective solution for online size analysis of iron ore pellets.Vision-based size classification of iron ore pellets using

Failure Analysis and Improvement Measures of Grate Bars Used in Iron

Stainless steel grate bars are one of the important components of pallet cars used in straight grate iron ore pelletizing plant. Their service life has a major influence on plant productivity and pellet quality. The objective of this work is to find the root cause of grate bars premature failure and suggest preventive measures. To reach this objective, During the roasting process of fluxed pellets in a coal-fired rotary kiln, the incomplete combustion of pulverized coal injection accelerates deposit formation, which further limits the production efficiency of fluxed pellets. In order to eliminate the above problem, this study investigated the influence of MgO on deposit formation mechanism. Deposit Formation in a Coal-Fired Rotary Kiln for Fluxed Iron Ore

Usage of High-LOI Iron Ore Fines in Pellet Making Springer

High-LOI iron ore fines are required for detailed laboratory pelletization studies and are used in pellet making. The received iron ore is martite–goethitic and hematite–goethitic form of ore with high LOI content. The iron ore consists of 57.7% Fe, 6.19% SiO2, 2.69% Al2O3, 8.80% moisture and 8.85% LOI. From thermo-gravimetric As part of efforts to reduce anthropogenic CO2 emissions by the steelmaking industry, this study investigated the direct reduction of industrially produced hematite pellets with H2 using the Doehlert experimental design to evaluate the effect of pellet diameter (10.5–16.5 mm), porosity (0.36–0.44), and temperature (600–1200°C).

Modeling Isothermal Reduction of Iron Ore Pellet

Iron ore pellet reduction experiments were performed with pure hydrogen (H2) and mixtures with carbon monoxide (CO) at different ratios. For direct reduction processes that switch dynamically The pellet size distribution is a key quality indicator that affects the combustion efficiency of the blast furnace and the quality of the iron ore pellets [3]. Therefore, to ensure that the pellet size distribution is within a reasonable range (diameter 9–16 mm), the variation in pellet size should be monitored and used as a feedback toOnline size distribution measurement of dense iron green pellets

The Deposit Formation Mechanism in Coal-Fired Rotary Kiln for Iron Ore

The deposit-forming problem is one of the main bottlenecks restricting the yield and production benefit of iron ore pellets produced by coal-fired rotary kilns. In order to implement measures to ensure the efficient production of pellets by coal-fired rotary kilns, the mechanism and influencing factors on the deposit formation were reviewed. The 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 Effect of Bentonite on the Pelleting Properties of Iron Concentrate
