DEFINITION

Classification: 241/68

(under the class definition) Apparatus provided with means to separate or classify the material undergoing treatment according to the physical characteristics of the parts separated.

(1) Note. See SEPARATION OF MATERIAL and Lines With Other Classes of the class definition of this class for notes to related art and for a statement of the lines followed with the separating classes.

(2) Note. Classification in this group is proper only if the separator consists of means other than the elements which effect the comminution. Where the separation is effected by the comminuting elements or a portion thereof, the patents have been classified elsewhere in the class. See, for example, subclasses 82, 83+ and 96.

(3) Note. For purposes of this classification, where material is subjected to a plurality of successive separating operations, without an intermediate comminution, (e.g., where

the material flows over and through a plurality of superposed screens) the operation is considered in its entirety as a single separation (i.e., separating zone) to obtain a plurality of grades.

24.1+, for the corresponding process. 38+, for comminutors combined with separators which involve the application of a fluid to the material.
