Kiln Network: So far, noise control in a ball on the research and development focused on structural and technical aspects of noise reduction equipment, and noise reduction materials is relatively small. Currently mill applied acoustic noise control, noise, vibration and damping materials are mostly traditional materials, such as glass wool, asbestos velvet porous sound-absorbing materials and perforated steel plate for thematic material; utilize steel, concrete, wall brick material of insulation materials; conventional rubber and heat-resistant rubber, asphalt-based paint and other materials to do damping damping materials. And equipment so that the noise reduction performance is a greater impact. Ball Mill by hundreds of tons of steel ball impact, and produce high-intensity, broadband noise, and the dry mill working temperature below 200 ℃ determine the characteristics of high-performance materials must be used for vibration and noise reduction. Reduce the impact of the ball decreases vibration generated machine cylinder surface acoustic radiation, is to govern from the noise source of the key. Stage used in place of steel liner rubber material, although damping performance, noise reduction effect is significant, aac plant  but poor body wear warm, life is short, since the damping material attenuation coefficient affected by temperature, the existing damping material in a ball mill operating temperature can not reach its designed performance indicators, vibration and noise reduction ability. So developers can adapt working conditions of thermal power plant mill new high damping materials, such as damping alloys, temperature resistant materials and viscoelastic damping coatings, etc., is the focus of recent research and development materials. Meanwhile, in order to more effectively control the transmission of low-noise, sound-absorbing insulation should also strengthen the development of new materials. Noise from the current materials research field of view, high-density, high damping, good softness composite plastic insulation material has good prospects for development.
