Magnetic separator magnetic cylinder with multi-end-cover supporting structure

The invention provides a magnetic separator magnetic drum with a multi-end-cover supporting structure, which comprises a main shaft and at least two drum skins, the at least two drum skins are connected through a middle end cover, and the outer sides of the drum skins on the two sides are respectively connected with an end part end cover; the main shaft respectively penetrates through the middle end cover and the end part end covers and is rotationally connected with the middle end cover and the end part end covers, and a plurality of magnetic systems are respectively fixed on the outer side of the main shaft; and one end of the main shaft is connected with a driving device. According to the invention, the magnetic cylinder formed by connecting the cylinder skins through the middle end covers is adopted, so that the length of the separation magnetic cylinder of the permanent magnet cylinder type strong magnetic dry separator can be increased, and the treatment capacity can be improved. 本发明提供了一种多端盖支撑结构的磁选机磁筒，包
