Problems solved by technology

[0005] The noise of the ball mill during operation reaches over 110 decibels, and the rotary part is the main noise source of the ball mill. In order to reduce the impact of the noise of the ball mill on the environment, a soundproof room is specially built for the existing ball mill, and the ball mill is

Example Embodiment

[0031] Example :

[0032] Such as Figure 1~Figure 11 As shown, the cylinder 1 of the ball mill is provided with an annular support wall 6 corresponding to the position of each bolt hole 4, and a sound insulation cover 2 that matches the contour of the cylinder's revolving surface is provided with a plurality of matching annular support walls 6. Each hole wall is connected with each annular support wall 6, thereby forming a vacuumable sound insulation cavity 3 between the soundproof cover 2 and the cylinder 1, and a support column 7 is arranged between the annular support walls 6 and the support column 7 is The connecting lining board 5 supports the soundproof cover 2; on the cylinder 1, two upper and lower manholes 8 protruding from the rotating surface of the cylinder are respectively provided near the feeding end 13 and the discharging end 14, corresponding to the manhole 8 Two manhole covers 11 are provided at the position of, and the manhole covers 11 are slidably connecte...

Abstract

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.

Description

technical field [0001] The invention relates to a ball mill, in particular to a ball mill with a noise reduction structure. Background technique [0002] At present, the ball mill is the key equipment for dry or wet grinding in industries such as silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metals, quartz sand, and glass ceramics. [0003] The whole ball mill is generally composed of feeder, discharge part, rotary part, transmission part, grading part and other main parts. The main body of the rotary part is a cylinder with a wear-resistant lining on the inner surface. There are two manholes at both ends. The cylinder rotates under the drive of the outer gear, sprocket or belt. The cylinder is divided into the first warehouse and the second warehouse by a single-layer partition board. The material is fed by the feeder. The mouth enters the cylinder, and enters the first chamber spirally and evenly through the hollow s...
