May 27, 2016· Roller mills can typi- cally handle raw materials with an aggregate moisture of 15% while ball mills are limited to about 8%. Ball mills used for drying should be air-swept using air velocity of 3-4M/sec above load. Normally drying is effected by ducting part of the kiln exhaust gas through the mill.
vent air requirement when grinding slag separately is around 15 per cent less than when grinding clinker or clinker and slag together, because the mill has to be set up for the lowest common denominator (which is clinker when it comes to early strength). Separate grinding typically requires two mills, or if one bigger vertical mill is
