One path primarily for the heavier media is through a perforated floor into means located under the floor from whence the exhausted blasting media is separated into reusable and non-usable media. The second path primarily for the lighter media that is suspended in the compartment is through filter means located at one end of the compartment. The particles of such media are intercepted by the filter means and then dispensed into the first path of the heavier particles for subsequent separation into usable and non-usable media.
