A roller press (1) is described for grinding of particulate material such as cement raw materials, cement clinker and similar materials, which roller press (1) comprises two oppositely rotating rollers (2, 3) forming between them a roller gap (4) and a co-rotating annular disc (5), which in concentric manner is attached to an end surface (6, 7) of one of the rollers (2) by means of a number of resilient attachment elements (8) and being movable in the direction of the roller axis, where the outer diameter of said annular disc (5) is greater than the diameter of said one of the rollers (2), hence the annular disc (5) in the area of the roller gap (4) extends toward the other roller (3), thus covering at least part of the roller gap (4). The roller press (1) is peculiar in that the inner diameter of the annular disc (5) is smaller than the diameter of the roller (2), to which it is attached, thus overlapping the end surface (6, 7) of said roller (2), and that the resilient attachment elements (8) are evenly distributed over the circumference of the annular disc (5) and provided with spaces or openings (10) there between. It is hereby obtained that the annular disc (5) does not get stuck by material to be grinded or destructive forces damaging construction parts are not accumulated. This is due to the fact that material in the roller press (1) according to the invention is allowed to escape from the area between the annular disc (5) and the roller (2) to which it is attached.

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).

A roller mill for crushing brittle material has two grinding rollers forming a grinding gap, and provides a delivery chute for feeding the material to the grinding gap. In the delivery chute at least one distributor device is arranged above a middle region of the grinding gap and extends above the grinding gap transversely to the longitudinal extent of the grinding gap and covers from 5 to 70% of the cross-section of the delivery chute. The material is delivered to the delivery chute and is crushed in the grinding gap, wherein the material is introduced into the delivery chute or is deflected in the delivery chute in such a manner that, based on the longitudinal extent of the grinding gap, coarser material accumulates in a middle region of the grinding gap than in the edge regions.
