Incoal milling for power stations, a ‘closed-loop’ process is used in which the rejects from the classifier are returned to themillfor regrinding. In VSMs, the re-circulation loop is within themill, but somemill typeswould have an external loop. In fact, there are a number of re-circulation loops within amillsystem.Chat Online
