Mining Screen for Spring Condition Monitoring
Minerals 2021, 11, 1076 2 of 14 In this article, one of the critical technical objects of the Ore Enrichment Plant—the vibrating screen used for the sieving process—is considered. The main purpose of sieving is to separate the fine fraction (suitable for milling) from the coarse fraction (requiring crushing).

Particle size analysis · Qmineral
A sieving analysis reports the weight proportion of material retained on each sieve of a sieving tower. A standard analysis uses following sieves: 4mm, 2mm, 1mm, 500µm, 250µm, 125µm and 63µm. The analysis can be performed on dry material but in case of much fine material, it is better to perform a wet sieving for optimal dispersion.
