2012-2-20Grinding systems are either open circuit or closed circuit. In an open circuit program, the feed rate of incoming clinker is adjusted to accomplish the desired fineness of the item. In a closed circuit program, coarse particles are separated from the finer product and returned for further grinding.Get A Quote
This will in particular be the case in open circuit grinding. Although this phenomenon is somewhat reduced in closed circuit grinding systems, the hard slag component will still difference in grindability of the two materials. This will in fineness of PFA usually.Get A Quote
