The new structure of the discharge end cover of the wet-process grate mill is proposed.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a new structure of the wet-process grate mill discharge end cover, including a discharge end cover body, a material lifting device is provided on one side of the discharge end cover body, and a discharge spiral cylinder is provided on the side of the discharge end cover body close to the material lifting device.

[0013] 1. In the utility model, the ground material passes through the discharging grate plate and enters the interior of the discharging end cover body. When the cylinder rotates, the lifting ribs of the discharging end cover body drive the material to be lifted into the discharging spiral cylinder and discharged from the cylinder.
