Cement mill - Wikipedia
A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into is generated. This is corrected by recirculating part of the hot exhaust air to the mill inlet. Because cement particles react with water at their surface, the specific surface area is directly related to the cement's initial reactivity .
