Rotary kiln dust prevention system noise

Article source：

Rotary kiln dust removal system to prevent noise generated from the root of grabs.Related problems can be solved to find the source, the fan is the main source of dust removal system noise generated from it will be able to start processing the issue is essentially eliminated. Sound-absorbing material attached to the fan housing, such as glass wool board, mineral wool sound-absorbing panels and other materials, the outer surface mounted galvanized steel.When the fan is disposed within the engine room, the health personnel in order to operate, sound-absorbing interior to take measures to reduce the noise in the room. Mainly to low-frequency noise in the room, therefore, should use low-frequency sound absorption properties of materials, such as gypsum perforated plate, perlite sound absorbing panels, glass wool board, mineral wool board.In addition, the room's walls, floor also has acoustic effect, sound effects and the wall, the floor surface density, surface density increases, the better the insulation effect.But only by increasing the thickness of insulation to increase the volume, not a good idea, in general, the thickness of the double insulation will also be able to increase the amount of 5dB (A) so, the best way to increase the amount of insulation in the walls, the floor of the increase air layer, if placed in an air layer sound-absorbing materials, better insulation effect.
