A magnetic drum for separating ferrous and non-ferrous beverage containers having a plastic drum which rotates around a series of permanent magnets mounted on a structural support. The plastic drum has an inner cylindrical portion coupled to a power roller which induces rotational movement in the plastic drum. An input chute funnels ferrous and non-ferrous crushed beverage containers onto the outer cylindrical portion of the plastic drum such that crushed ferrous beverage containers are held against the outer cylindrical portion and traverse a predetermined distance around the circumference of the outer cylindrical portion until they are no longer within the influence of the magnetic force field produced by the permanent magnets mounted between the outer cylindrical portion and inner cylindrical portion of the plastic drum. Non-ferrous beverage containers, such as aluminum containers, are not held against the outer cylindrical portion and are, consequently, horizontally displaced and separated from the ferrous beverage containers.
