Magnetite-dominated ore types are more likely to be affected in their comminution behavior by the presence of silicate minerals. In contrast, hematite-dominant ore types are instead influenced by the presence of apatite. A. Fredriksson, G. Adolfsson, and H. Lieberwirth. 2015.

Aiming to reveal the kinetic characteristics of ceramic ball grinding of fine magnetite comprehensively, two types of ceramic balls ground with the same filling rate and total weight as steel balls were researched. The results show that the breakage rate of ceramic ball grinding is only half of that of steel ball grinding with the same media filling Because the high-pressure roller mill is arranged in the process, the content of qualified size fraction materials (0-1.5mm) in the dry magnetic concentrate reaches 58%, the treatment capacity of the ball mill is improved from 500t/h to 800t/h and is improved by 60% by arranging the pre-screening operation before the first-stage ball milling.CN112170000A Pre-screening treatment system and process for magnetite

9.2.2.1. Iron minerals. Based on the magnetic susceptibility values in Table 9.1, iron minerals can be divided into two groups, namely strong magnetic minerals, that is, magnetite (72.4% Fe), and weakly magnetic minerals, that is, martite (70.0% Fe), hematite (70.0% Fe), specularite (70.0% Fe), limonite (57.14–59.89% Fe), and siderite (48.2% A cement Vertical Roller Mill modeling based on the number of breakages. Wang, Chen et al. 2009 use a matrix model to replicate the grinding process in VRMs. It was developed based on experimental data from cement clinker, coal grinding lines, and laboratory experiments [15]. VRMs are simulated using high-efficiency classifiers, matrix Grinding process within vertical roller mills: experiment and
