Roller press grinding plant

摘要

A grinding plant comprising: a high-pressure roller press for crushing raw material into fragments; a static cascade sifter for shifting the fragments from the high-pressure roller press into fine fragments and coarse fragments, the coarse fragments being returned to the high-pressure roller press; and a separator for separating the fine fragments from the static cascade sifter into fine product fragments and less fine reject fragments, at least some of the less fine reject fragments being returned to the static cascade sifter without first pasing through the high-pressure roller press.
