A magnetic separator useful for treating chips in a machine tool is disclosed, which comprises a separating cylinder, a plurality of magnetic plates arranged at an outer periphery of the cylinder and spaced apart each other, an inlet for a fluid suspension at a middle part of the cylinder, outlets for a separated fluid at one end and for the suspended matter, such as machined chips, at the other end of the cylinder, and a screw conveyor inserted into the cylinder in such a way that the screw conveyor is contacted at its peripheral edge with an inner wall of the cylinder. The magnetic plates are arranged in a circle around the cylinder with the polarity of the adjacent magnetic plates arranged in a special sequence for generating a maximum magnetic flux toward the axial center of the cylinder. Also, the magnetic plates extend from the inlet near the middle of the cylinder to both outlets at opposite ends of the cylinder for achieving a strong magnetization of the chips suspended in the fluid.

A magnetic separator for at least separating magnetizable solid matter suspended in a fluid, which comprises a separating cylinder having a top end and a bottom end, a plurality of magnetic plates of a predetermined size arranged at an outer periphery of the cylinder and spaced apart from each other

A magnetic separator for at least separating magnetizable solid matter suspended in a fluid, which comprises a separating cylinder having a top end and a bottom end, a plurality of magnetic plates of a predetermined size arranged at an outer periphery of the cylinder and spaced apart from each other, said magnetic plates being arranged in a circle around said cylinder with each magnetic plate having an adjacent magnetic plate of opposite polarity located to one side of it and an adjacent magnetic plate of the same polarity located at its other side such that said magnetic plates are arranged in a north-north-south-south-north-north-south-south- . . . sequence to thereby generate a maximum magnetic flux to substantially the axial center of said cylinder means defining an inlet for a fluid suspension arranged at a middle part of the cylinder, means defining an outlet for a separated fluid arranged at the bottom end of the cylinder and means defining an outlet for the separated suspended matter arranged at the top end of the cylinder, and a screw conveyor of a non-magnetic material within the cylinder and having a peripheral edge in engagement with an inner wall of the cylinder, said magnetic plates extending around said cylinder substantially along the entire longitudinal length of said cylinder from said bottom end near said fluid outlet to said fluid suspension inlet, and also from said inlet to said top end near said outlet for said separated suspended matter, whereby a strong magnetization of suspended matter is achieved.
