distinguish closed circuit and open circuit in cement milling
open and close circuit mill in cement industry
The cement mill. Grinding systems are either open circuit or closed circuit in an open circuit system the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product in a closed circuit system coarse particles are separated from the finer product and returned for further grinding
