摘要： The arcuate magnet is made up of a series of magnets that produce a radial shape magnetic field. The arcuate magnet is supported adjacent the outer periphery of the cylindrical blind trommel. The blind trommel is rotated. Steel balls and magnetic material are held to the inner periphery of the blind trommel and carried with it to the end of the arcuate magnet. The arcuate magnet may be made up of either electromagnets or permanent magnets. Another embodiment has one or more magnets attached to spaced positions around the outer periphery of the trommel. Permanent or electromagnets may be employed. Electromagnets are connected to slip rings that energize the magnets from about the 6 o'clock position and de-energize the magnets at about the 11 o'clock position. The permanent magnets are moved away from the blind trommel at about the 11:00 o'clock position. The magnetic material is released from the blind trommel at about the 11:00 o'clock position and collected in a tray inside the blind trommel. One magnet or a plurality of magnets can be used.

摘要翻译： 弧形磁体由产生径向形状磁场的一系列磁体组成。 弓形磁体被支撑在圆筒形无框式筛选机的外围附近。 盲人转盘旋转。 钢球和磁性材料被保持在盲筛的内周，并被带到弓形磁体的末端。 弧形磁体可以由电磁体或永磁体组成。 另一个实施例具有一个或多个磁体附接到围绕筛选机的外周边的间隔位置。 可以使用永磁体或电磁体。 电磁铁连接到从大约6点钟位置激励磁体的滑环，并在大约11点钟位置使磁体断电。 永久磁铁在大约11点钟的位置被移开远离盲孔。 磁性材料在大约11点钟的位置从盲卷轴中释放出来，并收集在盲筛板内的托盘中。 可以使用一个磁体或多个磁体。
