BAO ORIGINAL

This object is achieved according to the invention in that a ball or roller mill for the comminution of cocoa, chocolate lacquers, pigments or similar products according to the main application No. 19 56 785 is used, which consists of an outer cylindrical container, ¹ SeDi a rotor is provided, which is equipped on its outside with rollers or balls that are guided along a certain path and is characterized in that the inner surface of the stationary, tubular cylinder on the inside of the same in the circumferential direction has grooves which correspond. Limiting corresponding projections which have a flat surface which is aligned parallel to the axis of rotation of the rollers, and that said surfaces are limited by sharp edges.

The subject matter of the above invention will now be described in more detail using an exemplary embodiment and in the drawings shown. Show it

1 shows a section through a wall piece of the cylindrical, fixed container which cooperates with smooth, one-piece grinding rollers;

FIG. 2 shows a section through a wall piece of the cylindrical, fixed container according to FIG. 1, which, however, cooperates with several, subdivided, smooth rollers;

Fig. 3 shows a section through a wall piece of the cylindrical, fixed container in a further embodiment ^ which numerous, slightly curved rollers are used.

As can be seen from Fig. 1, the surface 1 of the wall 2 of the cylindrical, fixed container of the '

Mill (not shown) has numerous grooves that are located in Extend circumferential direction of the cylinder and numerous projections 3 that have sharp edges.

Due to the special design of the inner surface of the wall 1 of the cylinder 3 there is the possibility of using rollers 4 with a smooth surface for grinding wear-promoting substances.

This has the advantage that those formed with sharp edges Projections much less due to the grinding of Soil wear-promoting substances are worn out and that the possibility consists of using smooth grinding rollers 4, which are made, for example, of hard metal.

In the in Pig. 2 illustrated embodiment operates the inner surface 1 of the wall 2, which is formed with sharp edges Has projections 3, together with individual rollers 5, which in contrast to Pig. I illustrated roles 4 from numerous smaller roles are formed.

Like from the Pig. 3 can be removed, the wall 2 has slightly curved grooves 6 on its inside, in which corresponding arched grinding rollers 7 are guided.
