Discharging end cover of grate ball mill

The utility model discloses a discharging end cover of a grate ball mill. The discharging end cover comprises an end cover body (1), wherein more than two rib plates (2) are uniformly arranged in the end cover body (1) in the peripheral direction; steel plates (3) are arranged on the two sides of the rib plates (2) and are used for separating an inner space of the end cover body (1) to form small spaces without air circulation. Ore pulp does not form erosive wear around the circumference of a whole barrel body when the ball mill rotates at a high speed, so that the service life of the end cover is prolonged, and further, the service life before overhauling of the whole ball mill is prolonged.
