2014-2-1  When the new feed is more than 80.5 t/h, the value of a (min − 1) will be decreased with the increase of the circulating load and the grinding efficiency on cement clinker will be reduced. When the new feed has relatively low flowrate, the circulating load need not be increased to reach the suitable crushing rate and efficiency.

2020-3-17  mills and air classifiers are the main loads in terms of energy consumption. By using a high pressure grinding roll (HPGR) in pre-grinding or semi-finish grinding mode, savings of specific energy consumption up to 30% compared to ball mill in closed circuit can be achieved. The state-of-the-art technology is a HPGR in semi-finish grinding mode.
