Abstract
A deflectable vane member for a coal mill pulverizer throat. The vane is yieldingly mounted in the throat with a spring support member whose force is designed to hold the vane rigidly in place during normal operations, and to yield when the vane is struck by large debris with sufficient force. The spring support member causes the vane to spring back into its operative position after it has yielded to the debris.
