Cement mill - Wikipedia

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

However it sounds to me that the four separator dampers are being opened to cool the cement temperature. This will contribute to cooling the mill exit temperature but only because the reject returns from the O-Sepa will be at a lower temperature. For sure there is a danger of affecting the efficiency of separation by this mode of operation.

There is a common misunderstanding that to make a finer cement you should reduce the mill ventilation to keep the cement in the mill longer. In fact, this simply leads to over-grinding and increased void filling, which reduces grinding efficiency and often leads to a wider particle side distribution, increased separator rejects and eventual reduced mill output.
