ROLL FOR ROLLER PRESS, AS WELL AS ROLLER PRESS EQUIPPED WITH SUCH A ROLL Russian patent published in 2022 - IPC B02C4/30 

FIELD: material processing.

SUBSTANCE: group of inventions relates to a roll for a roller press and a press with such a roll that can be used for grinding granular material. The roll contains a cylindrical case with outer cylindrical pressure surface 21 for use with an opposing roll, a set of wear-resistant surface protrusions 22 extending outward, located on pressure surface 21. In this case, the cylindrical case is equipped with means 50 for limiting flow 40a of granular material in intervals between wear-resistant surface protrusions 22 extending outward along outer cylindrical pressure surface 21. The roller press contains at least one set of the two above-mentioned opposite rolls. The presence of means 50 prevents the movement of flow 40a of ground granular material, which is a protective layer of pressure surface 21, which increases the resource of rolls and the roller press.

EFFECT: increase in the resource of rolls and a roller press.
