Solid Control Equipment Drilling GN Coal Screen Scroll Centrifuge
Coal Screen Scroll Centrifuge
GNCD930 Vertical Screen Scroll Centrifuge allows you to handle coal from higher fines recovery and maintaining the lowest product discharge moistures possible. The GNCD930 Coal Screen Scroll Centrifuge is designed for fine coal drying with significantly high capacity per energy unit.
Working Principle of GN Coal Screen Scroll Centrifuge
The GN Vertical Screen Scroll Centrifuge uses centrifugal force to dry wet coal. A stainless steel screen bowl traps wet coal and accelerates them up 900RPM with G force to 420G. This G force is higher to most of GN competitors which will give better separation. Liquid is forced through the screen bowl openings, the openings of the screen is optional in different sizes, while “dry” coal are extracted by the angled flights or knives attached to the rotation cone, which rotate slightly slower speed than the bowl and screen. This differential speed is to push the dry solids or coal to discharge from the bottom of the screen centrifuge.
Tungsten carbide protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl of the centrifuge, which is crucial for proper operation.
