SCREENING ON A SCREEN WITH A VIBRATING SIEVE. 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.

Sieve analysis - Wikipedia

A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.
