筛子发生噪音的主要原因筛子发生噪音的主要原因有二:一是传动机构的振动,二是因筛子运动而造成煤或其他物料对筛板和受料板的撞击。一般地说,煤撞击筛板的噪音主要是在筛块煤时发生。传动噪音主要是在筛末煤时发生。此外,还有筛子各部件连接不紧而发出噪音。确定主要的噪音源构成筛子总噪音的煤撞击筛子和传动装置引起的噪音可以用测音计和耳朵听的
The main reason noise occurs sieve There are two main reasons for the noise of the sieve: First, the vibration of the transmission mechanism, the second is due to the sieve movement caused by the coal or other materials on the sieve plate and the impact plate. In general, the noise from the coal striking the deck mainly occurs when the coal is sieved. Transmission noise occurs mainly in the end of the sieve coal. In addition, there is a tight connection between the various parts of the screen and make noises. Determining the main source of noise Coal caused by the total noise of the screen hitting the screen and the noise generated by the transmission can be heard with the sound meter and the ear
