How to solve the noise of aluminum powder mill?

　　The noise phenomenon of the aluminum powder ball mill, not only affects the use of the equipment during use, but also harms the operation and personal health of the surrounding environment and operator, so we need noise of the aluminum powder ball mill. Solve.

　　Aluminum powder mill noise sources

　　1) noise generated by cylinders When the cylinder is rotated, steel balls are generated by steel balls, steel balls, and cylinders. Mechanical noise, the noise level of the cylinder outwardly can reach 115 dBA. On the top, the noise band is wider.

　　2) Electromagnetic noise generated by the noise motor generated by the motor and the transmission mechanism, the airflow noise generated by the fan. The motor noise is proportional to the motor power and speed, and its noise level is generally 90 dBA-115DBA. The mechanical noise of the transmission is mainly caused by mutual friction between the collisions and the components between the gears.

　　Aluminum powder ball mill noise control method

　　1) The damping sound insulation layer is wrapped in a housing of the aluminum powder ball mill to reduce the noise of the cylinder. This method usually reduces 5-10 dBA, and the effect is not ideal. 2) The soundproof shroud is used to close the barrel portion of the aluminum powder ball mill, block the noise transmission path, thereby reducing the radiation noise of the barrel. This method is more effective, and the noise reduction value can usually reach about 20 dBA. However, the installation of the soundproof makes it difficult to perform overhaul and operation. At the same time, due to the motor and transmission mechanical packages in the sound insulation, it is difficult to ventilate, difficult heat dissipation, and the maintenance work is also very inconvenient.

　　3) instead of rubber lining with manganese steel liner. The original manganese steel liner is changed to the rubber lining. The impact noise between the steel ball and the cylinder can be greatly reduced. The noise reduction value is 12-15 dBA. The effect is obvious, but there is still a problem with the life of rubber lining.

　　So quickly identify the noise of the small aluminum powder ball mill, so that it can better identify the problem, solve the noise phenomenon of the equipment as much as possible, and reduce the pair The environmental pollution environment protects the health of the operator.
