— While sieve bends are used for sizing, they are particularly useful as dewatering screens. They may also be used as a prescreening attachment to conventional vibrating screens. The fact that they do not move makes them easier to install and maintain, and cheaper to operate, than vibrating screens. 11.4.1.2. Vibrating screens

— Sizing coal is the process of segregating coal lumps that are similar in size. Coal passes over one or more vibrating screens/grates and the larger sizes not passing through each screen are separated. Coal is usually separated using grates of three sizes: coarse, intermediate, and fine. Each size follows a different path through the plant.

— What is a Vibrating Screen? Vibrating Screens are machines used to separate aggregates by particle size by means of an exciting force applied to the machine. The vibration lifts the material, causing it to stratify, allowing the smaller material to move from the top of the depth of material to the bottom of the material, thus exposing them to ...
