Screw Press – AKUPRESS BX

For paper industry sludges, we offer the screw press AKUPRESS BX. Here, the letter “X” of our AKUPRESS X line stands for a special patented control concept, which in combination with high torques is allowing to reach maximum dry contents. Here we build on the experiences gained from more than 700 AKUPRESS screw presses sold and delivered. Furthermore, Bellmer is the market leader for belt filter presses, specializing in sludge thickening and dewatering. In addition to the individual components, we supply a comprehensive range of machinery and equipment. This includes complete turnkey systems together with all relevant process control technology conveying systems and catwalks.

Typical applications of the AKUPRESS BX for dewatering are:

  • mechanical/biological sludges from effluent treatment,
  • mechanical sludges from deinking plants,
  • mechanical sludges from waste paper washing processes,
  • mechanical sludges from waste paper stock preparation.


  • Maximal dry contents
  • Patented torque control by movable screen basket
  • Flanged screw shaft
  • Interchangeable screen basket system
  • Closed hood construction

High performance

The key point is the movable screen basket of the screw press AKUPRESS BX. Hence with this system, the AKUPRESS reaches highest dewatering performance through continuous, automatic adaptation of the press zone to the respective sludge characteristics. We are able to reach dry contents up to 70 % TS. We assure high operating safety through our fully automatic plant system. Furthermore, the AKUPRESS BX is available in seven different sizes with screw diameters ranging from 250 to 1,400 mm. Generally, the AKUPRESS BX has a long service lifetime and easy maintenance due to armored screw spiral, flanged screw or split screen baskets. In addition, our screw presses have low energy consumption and operation cost. In short, the screw press AKUPRESS BX shows maximal system performance.
