Claim:
A magnetic separator for spacing a plurality of workpieces in face-to-face relationship, said separator comprising: a frame; a sub-frame assembled with the frame; an upper guide plate removably attached to the sub-frame and a lower guide plate assembled with the frame and vertically spaced apart from the upper guide plate to define a passage having an inlet opening and an outlet opening for workpieces moving through said separator; an upper pole piece adjacent said upper guide plate and assembled with the sub-frame, and a lower pole piece adjacent said lower guide plate and assembled with the frame, said upper and lower pole pieces providing a magnetic field operative to orient workpieces in said passage; and an adjustment mechanism assembled with the sub-frame and operable to vertically move the sub-frame with respect to the frame, to position the upper guide plate and upper pole piece vertically with respect to the lower guide plate; wherein the upper pole piece is vertically adjustable with respect to the upper guide plate, and the lower pole piece is vertically adjustable with respect to the lower guide plate; wherein at least one of the upper and lower pole pieces is assembled with the corresponding one of the sub-frame and the frame by at least one adjustment screw operable to vertically adjust the at least one of the upper and lower pole pieces with respect to the corresponding one of the upper and lower guide plates, wherein the at least one adjustment screw is accessible from above the magnetic separator or from below the magnetic separator; and wherein said upper guide plate includes first and second side walls interconnected by a lower end wall, wherein the upper pole piece is disposed between the first and second side walls and is detached from the lower end wall.
