This document discusses different types of screening. It defines screening as searching for unrecognized disease through tests on apparently healthy people. The main types discussed are: 1. Mass screening tests entire populations, like tuberculosis screening, regardless of risk. It finds hidden diseases for treatment but not prevention. 2.

Screening is the process by which granulated ore material gets separated into different grades of particle size. In other words, it's a mechanical process that stratifies (divides) particles according to a required size. Once particles have been divided, the screening surface opening then accepts or rejects the particles.

Crushed materials are often angular and require different screening. The presence of fines can increase the feed speed of industrial screening. Moisture forces the particles to stick together, which limits the efficiency of the process. The difference in size between particles is a key factor. Screening systems: types of screening
