<p>The invention relates to a press roll (1) for a roll press, in particular for comminuting highly abrasive materials, comprising a roll body (2) which has a plurality of pocket-like recesses (3) that are distributed over the circumference and are spaced from one another in the circumferential direction (T) on one or both roll edges, each said recess being formed so as to be open laterally and at the top. Only one hard body is removably inserted into each individual pocket-like recess (3) as an exchangeable edge protection element (5), and the length (L) of the pocket-like recesses (3) and the length (I) of the inserted edge protection elements (5) in the circumferential direction (T) is greater than the distance (A) between two directly adjacent recesses (3).</p> |
