Screening is the most common device for grading material in different sizes as required. Some of the required grading goes out with the material of unrequited size the lesser proportion, the more efficient the screening. Screening efficiency is an indication of under size material going to oversize. There are various types of screen with separate requirement and functions like rotor screen, Heavy Duty Triple Deck Vibrating Screen, Vibrating Circular Screen etc. which working on the technique of circular motion elliptical motion and resonance screens. The application of above category is for different purposes of screening.
Classify : Classifying is separation of a mass of particles into two or more grading.
Scalping : Scalping is done relatively large sieve openings. This is mostly done as relief. Screening before crushing and in order to prevent smaller pieces going into the crusher.
