ThyssenKrupp Magnettechnik Permanent magnetic spreading magnets As the name already indicates, this kind of spreaders only consists of permanent magnets. The front view can be seen below and has the following arrangement: Iron plate Typical arrangement of a permanent magnetic spreading magnet The arrangement of the spreading magnet can be seen. It represents an iron plate with permanent magnets sticking to them with the polarity specified; ‘north’ designates the north pole of the magnet which should be homogeneous on the complete area; ‘south’ designates the south pole of the other magnet. The sheet should stand perpendicularly on this area. The area of the magnets is covering about 90% of the working area. The dimensions of permanent magnetic spreaders are normally smaller, because of the tremendous attractive force, which can not be switched off. Due to this the max. system width will not exceed 250mm by a system height of 400mm. When the dimensions are getting smaller, there is no real choice than to take permanent magnetic spreaders. As a smallest dimension you can take a width of 70mm with a height of also 70mm. In this case you can even fan round shaped sheets like the lits of cans. An increasing spreading power can be achieved by using better magnet material. For such a case the typical ferrite magnet is replaced by NdFeB magnets. 1
