Abstract

A slide gate sealing system including a seal mounting frame disposed between the longitudinal rails and the intermediate and horizontal end frame members of a slide gate frame, a ball seal disposed in the seal mounting frame and having a mounting tail with a mating surface, a seal retainer to control the deformation of the ball seal under pressure, at least one isolation dam on the mating surface of the ball seal, and a ramping mechanism affixed to the interior side of the horizontal end frame member. The ramping mechanism includes a section of round material attached to the underside of the slide gate blade, and a ramping cam affixed to the interior side of the horizontal end frame member and having an inclined portion upwardly inclined toward the horizontal end frame member, such that when the slide gate blade is moved toward a closed position, the round material and the ramping cam cooperate to urge the slide gate blade upwardly so that the topside of the slide gate blade comes into positive contact with the ball seal.
