Functional principle of a vibrating screen The Allgaier vibrating screens are driven by a powerful vibration motor that generates an individually adjustable horizontal and circular tumbling motion. This causes the bulk material to move in a spiral pattern from the inside to the outside, resulting in efficient screening.

The first three natural frequencies of the vibrating screen are lower, and the second- and third-order frequencies are similar. (2) In order to avoid resonance, the design requires that the operating frequency of the vibrating screen must deviate from 10% of its natural frequency . In this study, the motor's operating frequency was 16 Hz.
