(2) To the separating f
22、alling down part of iron pieces of magnetic separator, attach a regulating cut and make such structure that the separated iron pieces do not mix in again during treatment processing. (3) To the magnetic separator and disc separator provide a suction apparatus so as the powdery dusts not to spatter t
