Abstract. 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 ...

Wüstner (1986) showed that 30% reduction was achieved after conversion of closed circuit ball mill circuits to a semifinish grinding circuit including HPGR. Applications of HPGR in different circuit alternatives have resulted in 1050% energy savings when compared with closed circuit ball milling operations (Patzelt, 1992).

Pebble Mill Grinding. Essentially tube mills and pebble mills may be considered as ball mills, the basic difference being that the ratio of length to diameter is greater. Usually the shell length is between 2 and 5 times the diameter. These mills are primarily used to grind various materials to 100 mesh and finer.
