WhatsApp: +86 18203695377Vertical stirred mills are usually charged with media occupying 80% of the mill volume which is in sharp contrast to tumbling mills that are seldom charged more than 40% of their volumes to allow space for the tumbling action to develop. The stirred mills are charged with a media size of 1012 mm and operated at a maximum tip speed of 38 m/s.

WhatsApp: +86 18203695377(1) The iron ore vertical roller mill has high production efficiency and greatly reduces the grinding energy consumption. Compared with the tube mill, the power consumption of the vertical roller mill is only 50%~60% of that of the ball mill, which varies with the moisture content of the raw materials.
WhatsApp: +86 18203695377Abstract The application of vertical mills in regrind circuits is consolidated. This type of mill is now attracting interest in primary grinding applications, due to its higher efficiency when compared to ball mills, which are usually used at this stage. In this study, a coarse sample of iron ore was tested in a pilot scale grinding circuit with a vertical mill.
