Batch grinding studies by a ball mill for hematite ore

Semi-industrial tests of a prototype of a new grinding equipment: A labyrinth disintegrator

“…These bricks are lining materials for blast furnaces, converter furnaces, electric arc furnaces and bottom refractories for induction and thermal heating furnaces. We found that all mills operating with grinding media are the most common type of grinders [5], contaminate the final product and overheating [7], [8]. It has been established that in the waterfall mode of a ball mill, the balls falling on the balls cut out thin steel petals from them so that about 150-200 grams are collected in one ton of grinding of such chips.…”

Research on the Grinding Energy Density in a Jet Mill

“…In grinding processes, energy consumption is a very important profitability criterion for the applied particular size reduction technology. The energy consumption of grinding is the subject of many studies, especially in the case of ball mills for grinding clinkers [8,9], fuels [10], iron ore [11], hematite ore [12], sulfide ore [13], wet ores [14], and in the case of stirred mills for grinding ores [15][16][17] and wet quartz [18]. In [19,20], the energy efficiency of various coals grinding in the ball-and-race mills is studied experimentally.…”
