re cement ball mill

Hi,

What is the maximum of the clinker size entering first chamber?

What is your damper percentage at the mill fan?

Your second chamber temeperature is too high, you need increace draft of mill fan and/or spray water in first chamber, depending on matrial temp. at middle diafragm.

You might have an incorrect ball charge.

Send me more info and we can discuss more.

re cement ball mill

Hi,

Dosent sound right!!!

what is the percentage of clinker with 60 mm overall?

check your diafragms and measure the opening. also check the opening in the middle of diafragms for blockages.

i dont understand what u mean by manual mill? do u have a separator? 

can u email the mill specifics? size, capacity? liner type? .....
