Disc thickener

Disc thickener is mainly used to wash and thicken pulp in pulping and papermaking process. Its working principle is to dewater by gravity through the level difference between pulp out of disc wire and white water in the disc. The pulp at the consistency of 0.8~1.2% enters the vat and then is attached to disc sector. The white water in the disc flows to the ends of hollow shaft through guide slot and then discharge out. Pulp attached on disc sector is knocked off by high pressure shower. The thickened pulp at the consistency 3~4% flows over the plate of adjusting valve into outlet vat where it is discharged out. The rotating speed of main shaft can be adjusted according to the required outlet consistency and capacity.

Design features:

Due to the structure of disc sector, the filtering area is large, allowing filtrating large amount of white water when operating.

Compared with the consistency by the common cylinder wire thickener, the consistency of white water filtrated is lower.
