DEFINITION

Classification: 241/79

(under subclass 68) Apparatus in which the material flows from a comminuting zone to a separator.

(1) Note. Classification in this subclass is proper only if the separation takes place in a zone that is so spaced from the comminuting zone that a conveying means would be necessary to return the material to the comminuting zone. For screen type separators wherein oversize material is retained in the comminuting zone, see subclasses 69+.

SEE OR SEARCH THIS CLASS, SUBCLASS:

49+, and 60, for such combinations in which the separation involves the application of a fluid to the material.

76, 77 and 78, for the above combination provided with additional separators and/or comminutors through which the material flows in series.
