Mill temperature is limited by supplying the mill with cool clinker, by cooling the recirculating air and, in some cases, by using an internal water spray This must do no more than cool evaporatively, of course, and the flow of water is controlled by monitoring the loss on ignition of the cement as it leaves the mill...
