The invention discloses a ball mill with a function of reducing running noises, which is characterized in that a ball mill body comprises a cylinder, and the cylinder is provided with a plurality of circles of bolt holes along the longitudinal direction of the cylinder; one section of the cylinder is provided with a manhole and a manhole plate which are protruded from the rotating surface of the cylinder, the outer side of the section of the cylinder provided with the manhole is provided with a manhole shield, and the manhole shield is movably connected relative to the cylinder; the outer side of the rest of the cylinder is provided with an annular shield, the annular shield is provided with operating holes, the positions of the operating holes are corresponding to those of the bolt holes, and the annular shield is rotatablely connected relative to the cylinder; an overlapping part exists between the manhole shield and the annular shield, and the annular shield of the overlapping part is covered in the manhole shield; the manhole shield and the annular shield are respectively provided with a vacuum cavity structure; and a layer of sound-proof shield packed on the rotating surface of the cylinder is arranged among the manhole shield, the annular shield and the cylinder, by which the noise of the ball mill can be reduced to 30 to 40 decibels. The invention has the advantages of reducing cost and occupied land area and improving the operating environment, therefore, the invention is especially suitable for horizontal ball mill.
