Disc Thickener – AKSE

AKSE is a hydrostatic disc thickener to thicken different suspensions which we offer in two types. The AKSE F can be used for thickening of fibrous suspensions such as fibre stock from chemical and mechanical pulp, and waste paper as well as fine rejects. The AKSE S is used for thickening of sludge and fine reject by adding a flocculant.

Thickening of fibres and sludge is fundemental for economical operation of downstream processes.

Depending on the customer demands, Bellmer offers a combination of dewatering systems including both AKSE disc thickener and AKUPRESS screw press. Here we build on the experiences gained from more than 400 AKSE disc thickeners we delivered.

At the beginning, the material enters between two discs which are rotating on a shaft. The hydrostatic dewatering process starts when the material drains through the mesh of the discs into the vat. At the end of the process, the discharge of the thickened medium is on the opposite side of the rotating discs.
