PROTECTIVE COVERINGS FOR SCREEN SUPPORTS ABSTRACT OF THE DISCLOSURE Apparatus for grading or classifying fine and coarse crushed ore particles and the like comprising a frame, at least one oscillatable shaker screen for separating the fine and coarse ore particles, an oscillatable, screen support deck, including support members underlying the screen and spaced to define passages which permit the fine ore particles to vertical- ly pass, and shield members shielding the support members from abrasion by the fine ore particles passing through the screen. The shield members near the upstream end of the support deck - i.e. that end at which material to be separated is passed on to the screen - take the form of a resilient covering mounted on the support members while the shield members adjacent the opposite end of the deck take the form of a hardened metal shield of umbrella shaped transverse cross section.
