Air and at least some powder that would have been wasted without the reclamation device is collected by the collector and re-fed to the mill through the connection. Preferably, the collector includes a shroud that extends into the collector. Also, a closed loop grinding mill that includes such a reclamation device, and a method of upgrading existing mills to include such a reclamation device.
