DEFINITION

Classification: 241/24.15

Sorting by use of sieve:

(under subclass 24.13) Process of comminuting and separating including utilizing a member having a mass of restrictive openings to pass through the small particles of a first component of material and prevent passage of the large particles of the second component.

(1) Note. The first and second components of this subclass are of different material, not simply large and small particles of the same material.
