Identify and resolve mill ventilation problems in cement

There is a common misunderstanding that to make a finercementyou should reduce themill ventilationto keep thecementin themilllonger. In fact, this simply leads to over-grinding and increased void filling, which reducesgrindingefficiency and often leads to a wider particle side distribution, increased separator rejects and eventual reducedmill…
