2. Grinding:
 

      By definition, a sieve retains oversized particles and lets appropriate sized ones pass. Strictly speaking, rotary sieves should rather be called homogenizers, as they break down oversizes to a defined maximum size and do not retain any. The same applies to oscillating sieves, where transport energy is supplied either by centrifugal force or by an oscillating tool. Using rasp-like rotors milling is also possible, which may be necessary if hard lumps should be passed through the dyes.
