Abstract
A powderizing assembly includes a product line for receiving product sized powderized material from a powderizing mill, and a purger assembly for receiving non-product sized material from the mill. Non-product sized material is periodically removed from the mill and fed to the purger. The purger assembly includes a purge line in parallel with the product line for receiving material from the mill. The purge line includes a cyclone separator and a filter. A first valve is operable to direct material from the mill to one of the product line or the purge line. The first valve and a second valve are operable to isolate the product line from the purge line. A method of purging a powderizing mill includes providing a purger assembly in communication with the powderizing mill, diverting flow from a product line in communication with the powderizing mill to the purger assembly, and interrupting a size classifier of the powderizing mill to allow non-product sized material from the powderizing mill to be fed to the purger assembly.
