influence of lime in the iron ore pellet making

Pelletizing WikipediaDevelopment on Iron Ore Pelletization Using Calcined Lime

The formation of raw iron ore pellets also known as pelletizing has the objective of producing pellets in an appropriate band of sizes and with mechanical properties high usefulness during the stresses of transference transport and use Both mechanical force and thermal processes are used to produce the correct pellet propertiof good quality iron ore pellets 2 Experimental Hematite iron ore fines of Noamundi India have been used as raw materials Olivine has been used as MgO source in some experiments limestone or calcined lime has been used as CaO input to increase the basicity of pellets and coke breeze is used as carbon source All the raw materials

EFFECT OF SIZE OF IRON ORE PELLETS ON ITS REDUCTION The Effect of Lime Addition on Reduction of Iron Ore Pellets

Use of iron ore pe llets not only increase the productivity of the plant but also produce good quality iron So it is essential to know about the various factors which affect the reducibility of th e iron ore pellet In our project we aim at studying the effect of size of iron ore pellet on i For the commercial production of iron ore pellets from hematite ores as it is practiced in various pellet plants the addition of lime has shown to be an efficient means with a view to improving cold compression and abrasive strength of the indurated pellets considerably

Effects Of Induration Conditions On The Structures And Iron Ore Sampling Systems High rigidity Sampling Systems

The influence of three important para meters which affect the induration of iron ore pellets viz temperature time and lime content have been assessed in terms of internal pellet structure and commonly used pellet quality criteria The pellets studied were produced from a typical hematite ore from the Pilbara area of Western Australia using a 25 cm Iron ore is a mineral assemblage that contains iron or iron compounds for economical use The iron ore quality is much important for each factory The amount of the iron will influence the price and classification of the iron ore So making iron ore sample is necessary for us before purchasing the iron ore
