Part 1. Theory of Screening The purpose of screening is to separate from a granular substance particles that are smaller be recovered; then efficiency is the weight percent of material in the screened oversize fraction compared to the total weight of oversize in the feed.

Trommel screen

Trommel screens can be used in a variety of applications such as classification of solid waste and recovery of valuable minerals from raw materials. Trommels come in many designs such as concentric screens, series or parallel arrangement and each component has a few configurations. However depending on the application required, trommels have several advantages and limitations over other screening processes such as vibrating screens, grizzly screens, roller screens, curved screens and gyrat
