Working principle
How the equipment works
Pulp slurry forms a mat on the rotating drum surface under vacuum. Wash water displaces liquor through the pulp mat, filtrate is collected through the valve system, and washed pulp is discharged for the next process stage.
Applications
Typical applications
Application scope can be refined according to process flow, material characteristics and production capacity.
