The vibrating screen is a kind of mine classification machine for ore, mine, sand, gravel, coal, slurry, etc. which consists of a screen and a vibrator. Generally below 50 mesh for the coarse screen, and 80 mesh for the fine screen. The vibrator is an eccentric wheel that rotates under the motor's drive, making the sieve frame vibrate.

In coal preparation, screening machines serve two purposes: sizing and media recovery. Oftentimes, the initial screening is performed by a scalping screen located outside the plant. This prevents the screens inside the plant from becoming overloaded. The deslime screens make the next cut and most prep plants size to minus 1 mm.
