how to grind iron ore fines particle 2

The study reveals that the blending of fines with coarse iron ore at a controlled particle size distribution supplemented by small dosages of low-cost additives may be employed for preparation and transportation of high-concentration iron ore slurry with improved pipe economics. Keywords: iron ore, high concentration, rheology, bio-additives

    Estimation of Grinding Time for Desired Particle Size

    Jan 03, 2020 The particle size analysis of the three iron ore feed samples is given in Fig. 4. It was observed from the feed analysis that 80% passing of the particles is of sizes below 2.5 mm, 2.4 mm, and 2.7 mm for the HSHA, LSHA, and LSLA iron ore samples, respectively. The density of all the three feed samples was determined using the Pycnometer
