Chat OnlineDefinition of closed-circuit grinding A size-reduction process in which the ground material is removed either by screening or by a classifier the oversize being returned to the grinding unit. Typical examples are a dry pan with screens dry milling in an air-swept ball mill and wet milling in a ball mill
Chat OnlineAG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill. Because of the range of mill sizes available AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. A diagram of types of AG/SAG
Chat OnlineThe design of the IsaMill results in a sharp product size distribution meaning that the IsaMill can operate in open circuit (i.e. without the need for an external separation of the discharged particles in screens or hydrocyclones to allow coarse over-size product to be returned to the mill for a second pass).
Chat OnlineTwo types of charge motion can be described Cascading and cataracting Ball mill. Two types of charge motion can be described cascading ` Mills are driven at speeds of 50-90 of critical speed. ` High speeds = coarse grinding Rod Mill ` Generally run in open circuit since it produces relatively controlled size reduction ` Reduction ratio
