The relationship between the number of revolutions and the screening efficiency
The data in this laboratory shows that the amplitude is large, the penetration rate of the sieve is not good, and the efficiency is reduced. Therefore, the principle of rotation speed and screening efficiency is that high frequency is proportional to amplitude.
1. Vibration number represents frequency
2. Increase in frequency and decrease in efficiency
3. Inconsistent with the principle (high frequency and low amplitude)
