Speed of air inside on a cement mill Page 1 of 1

2011-2-3  Re: Speed of air inside on a cement mill. I will answer you only first question: a typical average of air speed in a tube mill is between 1.0 and 1.5 m/s. If you have a static separator the speed could reach up 2.5 m/s. Best regards, Ariel . Reply
