Abstract
Apparatus for removing frozen electrolyte bath from surface portions of an electrode body, the apparatus having crust breakers adapted to penetrate and fracture the crust which breaks into discrete pieces and which separates from the body. The crust breakers are attached to a frame through a linkage system which is adapted to move the breakers along a line of travel substantially adjacent to the salt encrusted surfaces of the body. With application of sufficient power to the crust breakers to penetrate and fracture the crust, substantially all of the crust is removed from the electrode body with minimal generation of dust and noise.
