Abstract
A grinding machine comprised of adjustable grinding mechanism for grinding material into preselected sized grounds. The grinding mechanism includes a stationary grinding burr and a grinding burr affixed to an axially adjustable rotor assembly. The rotor assembly includes on its face opposite to where the grinding burr is located a vane assembly which is designed to insure that any of the ground material that seeks to move into the cavity in which the vaned portion of the rotor and other adjustable mechanisms are located is evicted from said cavity to prevent fouling of the adjustable mechanisms located therein.
