Screening Theory and Practice

Screening Theory and Practice 1 Part 1 Theory of Screening The purpose of screening is to separate from a granular substance particles that are smaller than the screen opening from those that are larger This is not as simple as it sounds and the difficulties compound as the opening becomes smaller For example if a sample of a crushed...
