PATENT OFFICE.

In the case of magnetic processing on a wet or dry route, it is possible to especially when the material to be cut is directly on the magnetically effective cutting surface is abandoned, do not avoid sticking to the pole edges, points or prongs magnetic good particles include a certain percentage of non-magnetic good. This is either the application or

ίο the enrichment depressed.

Attempts have been made to remedy this malady by various means, e.g. B. by Shaking movement of the cutting surface or by refining agents such as rinsing water, air and others. m.

The use of these remedies, which also more or less affect the vaginal process itself, but relatively narrow limits are drawn, and one has especially with wet magnetic herds, on their corrugated Surface the divorce is supposed to take place, has only achieved very imperfect results. This is because, for example, if there is an increased use of the lauter shower, apart from the high water consumption, the drawback that already attracted magnetic Good particles from the pole tips or prongs are rinsed off again and as a result to the non-magnetic come.

The method according to the invention consists in an effective mechanical loosening the good particles attracted by the pole edges in the area of the magnetic field, through which the release of the non-magnetic Particles are facilitated, but the separation of the magnetic material is in no way significant is affected. Rather, the application of the new method also offers the main advantage that you can use relatively small amounts of lauter water (or air) can get by, and furthermore the obtained separation products are so perfect, that only now, in many cases, the economic application of the magnetic treatment process is made possible at all with the help of known cutting devices.

The method is carried out essentially in such a way that it is done at the pole edges Adhesive material in the area of the magnetic field by means of comb-shaped or brush-shaped loosening devices that are moved relative to the cutting surface processed and by means of this »hacking through« of the magnetically held together Good causes the release of enclosed non-magnetic components.

On the drawing are shown in Fig. 1 to 3, two embodiments of loosening devices for example, which are used to carry out the new method.

In Fig. Ι and 2 the working area of a so-called ring separator is partially. shown in section and seen from above. R is the separating ring, the conical working surface of which is provided with corrugations or serrations Z to achieve local field densities. P is an excited opposite pole of, for example, a star-shaped magnet system. The corresponding working area of the separating ring R is located
