In the last chapter we introduced the Rotary Kiln processing equipment noise processing, continue processing noise Rotary kiln section today.In several parts of the deal we will see from the noise characteristics and the surrounding situation. Rotary kiln area within the primary noise source material grinding noise source device to its fans, lime Rotary kiln exhaust fan, heat fan.On the fan motor unit equipped acoustic enclosures, acoustic enclosures for the assembly of removable depicted with access door insulation, sound insulation observation window, top acoustic cover device exhaust fan motor way to ensure the adoption of forced air ventilation, and in the corresponding position open vents, device into the exhaust muffler.In the fan housing and inlet and outlet acoustic shell be bandaged, wrapped acoustic noise reduction at 8 ~ 10dB (A).
