1. Coal Mining Vibrating Screens is composed of two-way distributor, automatic moving device, special sieve plate, exciter, motor, damping spring, maintenance platform, anti blocking drop tube and other components. 2. The sieve body does not vibrate, sieve core vibration, vibrating screen of the dynamic load is similar to other screening.
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.
Crushing Screening Raw coal is transported to crushing workshop by belt conveyor. First, it is pre screened by a circular vibrating screen with a sieve opening of 50 mm. +50mm materials and extra large gangue enter the crusher and are crushed to – 50mm, and then transported to the coal washing workshop together with -50mm raw coal that under the vibrating screen.
