Today, one of Jet Mill manufacturers, Shandong AlPa Powder Technology Co., Ltd., talk to everyone about the noise problem of Jet Mill!
The research and production practice have shown that the higher the airflow speed of Jet Mill, and the product obtained is finer. When the ultrafine product is to be obtained, the airflow speed of Jet Mill must be supersonic.
In order to obtain a finer product, people have increased the speed of the air to 2-5 Mach. However, as the airflow speed and the Mach number increase, the noise generated by the high-speed airflow increases, especially for the disc-discharge disc Jet Mill, when Jet Mill is more than 3 Mach, The noise actual value in the nearby mouth is 130 dB (a), which seriously affects the physical and mental health of the operator, causing the hearing decline, flustered, and this hearing injury cannot be recovered.
The sound of people can't concentrate, distracting, often led to the incident. Since the Jet Mill itself is special, that is, the exhaust port is used for the discharge of high pressure gases and the discharge of the ultrafine powder product, the design of the muffler can reduce noise and does not affect the discharge, which is proposed for the structural design of muffler. Very strict requirement. The multi-stage cyclone separator and a large dust removal device and the wind turbine are currently typically disposed.
The above related issues related to Jet Mill's noise issues are provided by one of Shandong Jet Mill manufacturer, one of the Shandong Alpa Powder Technology Co., Ltd.!
