1/5/1999· When higher energy levels such as 45 kWh/ton are considered, above the same size (90 μm) interground PN has 2.4% material and separately ground P + N has 149% of this value (∼3.6%). This means that grinding to higher energy levels makes separately ground cements relatively coarser when compared with interground cements.
