Screening Theory and Practice 1 Part 1. Theory of Screening The purpose of screening is to separate from a granular substance particles that are smaller than the screen opening from those that are larger. This is not as simple as it sounds, and the difficulties compound as the opening becomes smaller. For example, if a sample of a crushed

Screening on a screen with a vibrating sieve 29 facilitates the exchange of sieves but much deteriorates the process of screening. Taking into account a growing durability of sieves produced now, the system with double-sided excitation of the sieve motion seems to be more recommendable. Fig. 1.

The purpose of the vibrating screen is that particles are introduced to the gaps in the screens repeatedly. The frequency of the screen must be high enough so that it prevents the particles from blocking the apertures and the maximum height of the particle trajectory should occur when the screen surface is at its lowest point.
