Screening - Criteria of choice and calculation of a screen

This second dossier on screening provides an industrial response to unit screening operations and the use of the equipment described in the first dossier [J 3 101] . The engineer may find himself in a variety of situations:

• where he must choose a device according to a certain number of usage constraints;

• where he has to calculate a screen, in which case his approach differs depending on whether he's a designer or a user.

In order to present a concrete situation, we focus on the mechanical preparation of ores, a case which is all the more interesting as each ore and each beneficiation plant has its own specificities. It is nevertheless necessary to emphasize the observations that need to be made to define a case realistically.
