Abstract

Dans des installations de broyage fin en particulier d'échantillons de matériaux pour des expériences de laboratoire, avec un organe de broyage fixe et un autre tournant, qui sont disposées de façon à avoir une surface située vis-à-vis d'une autre avec un intervalle faible et à faire transiter entre elles le produit à moudre, se pose le problème suivant: les échantillons doivent être introduits et évacués un par un, si bien que le travail s'effectue de manière discontinue. Il est également difficile de régler dans les grandes lignes le degré de broyage. Afin de résoudre cette difficulté et de pouvoir effectuer dans ce domaine d'utilisation un broyage continu de matériaux durs et très durs, ainsi qu'un broyage réglable dans les grandes lignes quant à la grosseur des grains, on a donné, conformément à la présente invention, aux organes de broyage, d'une part, une structure de corps de cylindre fixe (22) et, d'autre part, une structure de noyau de cylindre (26) tournant parallèlement à l'arbre; entre eux, un passage annulaire étroit, de préférence de l'ordre de grandeur d'un demi-millimètre, reste libre. Le produit à broyer est introduit sur le côté avant du noyau du cylindre et le produit broyé est évacué sur l'autre côté avant du noyau du cylindre; des dispositifs correspondants (20, 36; 21, 37, 38) sont prévus à cet effet. L'axe médian longitudinal commun des deux organes de broyage peut être basculé par des mécanismes appropriés (11, 12, 15) de manière à prendre une position pratiquement verticale en passant par d'innombrables positions inclinées. Un élément conique (30) dans la surface supérieure du noyau du cylindre (26) peut être disposé sur au moins un côté avant de ce dernier.In fine grinding installations, in particular of material samples for laboratory experiments, with a fixed grinding member and another turning point, which are arranged so as to have a surface situated opposite one another with a short interval and the product to be ground between them passes the following problem: the samples must be introduced and removed one by one, so that the work is carried out discontinuously. It is also difficult to broadly adjust the degree of grinding. In order to solve this difficulty and to be able to carry out in this field of use a continuous grinding of hard and very hard materials, as well as an adjustable grinding in broad outlines as to the size of the grains, we have given, in accordance with the present invention, to the grinding members, on the one hand, a fixed cylinder body structure (22) and, on the other hand, a cylinder core structure (26) rotating parallel to the shaft; between them, a narrow annular passage, preferably of the order of magnitude of half a millimeter, remains free. The product to be ground is introduced on the front side of the cylinder core and the ground product is discharged on the other front side of the cylinder core; corresponding devices (20, 36; 21, 37, 38) are provided for this purpose. The common longitudinal central axis of the two grinding members can be tilted by suitable mechanisms (11, 12, 15) so as to assume a practically vertical position by passing through innumerable inclined positions. A conical member (30) in the upper surface of the cylinder core (26) can be arranged on at least one front side of the latter.
