Definition of closed traverse. i. A surveying traverse whose accuracy can be checked by the fact that, when it is closed, the angles should add up to 360 degrees, and which ends at its starting point. Ref: Hammond. ii. A surveying traverse that starts and terminates upon the same station or …
creates the potential for increased capacity in closed circuit grinding. In 1925 E.W. Davis conducted tests which made comparison between rake classifiers, spiral classifiers and vibratory screens in the closing of grinding circuits. He concluded that vibratory screens provided both higher capacity and better control over grind size
Definition 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 with a classifier. See Also ...
