Investigation on the particle size and shape of iron ore pellet feed using ball mill and HPGR 911 surface areas were prepared (Table 2). The theoretical SSA Blaine is provided in Table 2 based on the previous research (Abazarpoor and Halali, 2016). Grinding was performed in a pilot high pressure grinding rolls (HPGR), with the
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
The iron ore pelletizing process consists of three main steps: 1. Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives anthracite, dolomite and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process; 2.
