The screening capacity of a vibrating screen is calculated using the formula: Capacity = screen area × efficiency × material feed rate. The size of the screen and the mesh size, the amplitude and frequency of vibration all determine the rate at which material can pass through. Other characteristics such as density of the material, moisture content and the size distribution of the particles also affect capacity. Through adjusting these parameters, the screen’s performance can be optimized, and thus, achieve a higher throughput for certain tasks.
