Aug 03, 2016· Cold bonding is a low-temperature alternative to heat induration. Pellets can be cold bonded using lime, cement, sponge iron powder, and organic materials such as starch and flour. Cold bonding consumes less energy than heat induration, and has found favor for bonding self-reducing pellets and for refractory ores that are difficult to heat-treat.

Dec 28, 2013· Cold crushing strength of pellets found to increase with increasing firing temperature. Decrease of mean particle size (MPS) does not have a relationship with the pellet strength, but it reduces the porosity of the pellet. Fluxed pellets exhibits good strength, improved reducibility, swelling and softening melting characteristics.

Table of ContentsMaterials and EquipmentGreen Pellet TestingDry Pellet TestingEffect of Test Variables For many years the green and dry compressive strengths of pellets have been considered as possible criteria of pellet performance during induration. Although widely quoted throughout the industry, little attention has been given to standardizing the unfired pellet compressive strength test or
Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %). Normally pellets are reduced considerably faster than sinter

This machine is mainly used in crushing strength test for iron ore pellet, with functions of automatically statistical analysis of iron ore pellets test result as average crushing strength, CV% standard deviation (SD) and calculate CCS force..
Oct 16, 2020· In this study, the effect of colemanite and calcined colemanite (CC) addition on the properties of iron ore pellets is studied. The pellets are prepared in a lab without and with 0.2% colemanite and varying amounts of CC from 0 to 1.0 wt% in steps of 0.2%. A reference pellet is prepared under typical plant conditions, and the properties of the reference pellet are considered as the base

Variables Affecting Pellet Properties: Pellet making is a complex process, requiring careful attention to the successive stages of feed preparation, balling, drying, firing, and cooling. Thus although the properties of the finished pellets are developed during the thermal induration or firing stage, the firing time and temperature are not the only variables which affect pellet properties. Ore

Lime is usually present in pellets and increases the pellet base index. Lime in normal condition and with dimensions of about 0.1 to 3 mm causes the loss of pellet strength and for this purpose it is used in the calcined form with dimensions less than 0.5 mm. Lime such as lime milk, if more than 5% enters the pellet, causes the mechanical resistance of the pellet, so it is necessary to observe
