Get PriceVariables 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.
Get PriceAn iron ore pelletizing plant.Green pellet strength is described by two test values, that is by drop number and compression strength.The drop number describes the green pellet strength during a fast impact such as the impact that occurs during unloading from a conveyor belt.The drop number must be high enough for the green pellets to.

Get PriceThe 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.
Get PriceIron ore pellets are largely characterized by inherent physical and chemical properties of ore as well as pelletizing conditions including induration time, induration temperature, etc.These parameters essentially vary with types of ores.The production of high-quality pellets from hematite ore is challenging because of high level of fineness blaine number and induration temperature.
Get PriceThe production of iron ore pellets at jsw steel limited involves the drying of iron ore fines to get the moisture less than 1 and grinding the dried material to get the required fineness 45 m size 62.Prior to the formation of green pellets, the ground ore is mixed with small amounts of binding agents such as bentonite 0.7 to 0.9, fluxes such as limestone to get the pellet.
