Class Information
Number: 264/15
Name: Plastic and nonmetallic article shaping or treating: processes > Spheroidizing or rounding of solid particles
Description: Processes directed to the reshaping of solid, irregular or nonspherical particulate matter wherein said irregularities are diminished or the particles are caused to become more spherical or rounded in shape without loss of material therefrom and by means other than use of a mold or shaping surface therefor and in which the individual and separate identities of the particles is maintained.
