Noise reduction system for cement grinding production line

Abstract

The invention discloses a noise reduction system for a cement grinding production line. The production line includes a mill (1), a ball mill (2) and a conveying corridor. The mill (1) is a fully enclosed structure; On the inner wall of (1), be provided with sound-absorbing body (4), and described sound-absorbing body (4) is plate-like structure, and sound-absorbing body (4) is supported on the wall of mill (1) by connector Above, the sound absorbing body (4) is parallel to the wall of the mill (1) and a gap is provided. Adopting the above-mentioned technical scheme, targeted noise reduction measures such as noise reduction and sound insulation are adopted for cement mills and other high-noise production workshops, which not only meet the needs of equipment ventilation and heat dissipation, but also control the external noise transmission of ball mills, centrifugal fans and other equipment, effectively reducing the noise Reduce the pollution of noise to the environment and ensure the stable operation of the grinding production line.

Description

technical field [0001] The invention belongs to the technical field of building material production process equipment, and relates to noise control and environmental protection technology for cement production equipment. More specifically, the invention relates to a noise reduction system for a cement grinding production line. Background technique [0002] In the cement grinding production line, a large amount of noise pollution will be generated during the operation of equipment such as ball mills and centrifugal fans during the production process, which will affect the original acoustic environment of the factory area and factory boundary, and then affect the normal operation of the production line. [0003] The noise of the ball mill is mainly generated by the impact and grinding between the steel balls in the cylinder, the material and the liner, and the noise is radiated from the surface of the cylinder. In addition, the motor, reducer, coupling, and transmission device ...
