Jul 10, 2018· If temperature of themillgoes above 110 o C due to lessventilation. De-hydration of the gypsum takes place and creates quality problems like false set and low fluidity ofcement. It causes coating in balls and liners and reduce thegrindingefficiency of themill. For limestone or rawmeal grindingthemilloutlet temperature should be around 100 o C.
Operation and Elements of a ClosedCircuit Ball MillSystem.Cement ball millstypically have twogrinding chambers. The first chamber is filled with larger diametergrindingmedia and lined with lifting liners. The first chambercoarse-grindsthe feed material and prepares it for the second chamber. The second chamber is the finegrinding chamber.

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