Variables Affecting Iron Pellet PropertiesProcess Fans in Iron and Steel Industry Reitz India

Variables Affecting Pellet Properties Pellet making is a complex process requiring careful attention to the successive stages of feed preparation balling drying firing and coolingThus 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 propertiNov 13 32 Pelletizing Fans Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200mesh with additives like bentonite and then shaping them in to oval/spherical lumps of 8 16mm in diameter by a pelletizer and hardening the balls by firing with a fuel
