Energy-saving ball mill

The utility model discloses an energy-saving ball mill. The centre line of a cylinder body is tilted at a tilting division barn plate in the cylinder body, the grate holes on the tilting division barn plate is in a tilting status with the plane of the tilting division barn plate and the tilting direction is from the front barn end of the grate holes tilting towards to the centre line of the tilting division barn plate. The ball mill can effectively eliminate the stagnant zone of a milling body in the mill to cause the milling body to generate compound movement in two ways vertically and horizontally. The impact and milling action of the milling body are strong, meanwhile, the screening grading ability of the tilting division barn plate is strong, which cause the utility model is provided with obvious effects of increasing production and saving energy.
