Sieve rings determine the final fineness of the specimen. Sieve rings with trapezoidal perforation and round perforation are offered. Sieve rings with round perforations are recommended for comminution of brittle materials and materials of medium fineness with a narrow grain width band. Sieve rings with trapezoidal perforations provide additional size reduction through increased shearing action.
