  • Trommel screen - Wikipedia

    A trommel screen, also known as a rotary screen, is a mechanical screening machine used to separate materials, mainly in the mineral and solid-waste processing industries. It consists of a perforated cylindrical drum that is normally elevated at an angle at the feed end. Physical size separation is achieved as the feed material spirals down the rotating drum, where the undersized material ...

  • Ore, Rock & Aggregate Screening (Complete Guide)

    A simple definition of a "screen" is a machine with surface(s) used to classify materials by size. Screening is defined as "The mechanical process which accomplishes a division of particles on the basis of size and their acceptance or rejection by a screening surface". Knowledge of screening comes mainly from experience.

  • Maximum Aggregate Size & Nominal Maximum Aggregate Size

    In the gradation example above, the nominal maximum particle size is 3/4" because the 3/8" is the first sieve to retain more than 10% of the material (11%) under the MS-2 definition. In yet another definition, the Asphalt Institute's SP-2 guide for Superpave Mix Design defines maximum size as "one sieve size larger than the nominal maximum size".
