The over-grinding phenomenon of the grinding process is severe and the grinding efficiency is also significantly lower; however the overflow ball mill has a simple structure is inexpensive and is suitable for fine grinding equipment so overflow ball mills are also widely used in production practice.
They can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work done by a ball millSag mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult if not impossible.
Tumbling mills eg ag sag rod and ball mills conventional reciprocating crushers eg jaw gyratory and cone hpgrs tumbling mills are described using indices m ia and m ib crushers have one index m ic hpgrs have one index m ih for tumbling mills the indices relate to coarse and fine ore properties plus an.
Unlike rod or ball mills hpgrs reduce particles by compressing and crushing the feed between two counter rotating parallel rollers with a small gap between themThis forces the rocks against each otherThere are no rods or balls that need replacing and it reduces energy consumption by about 40 for certain ore types breneman said.
