Screw press – AKUPRESS AL & BX

We offer different product solutions for the wet digestion processes depending on the specific customer application. Where a phase separation of digester output from wet digestion shall be made, the AKUPRESS AL is used. The AKUPRESS AL screw press allows a simple and low-cost dewatering/separation process. The pressure of the screw press results from the double-thread screw with adjusted flight heights and special spiral design. Counter pressure is adjusted through throttling and here lamella can be set pneumatically. The screw speed can be adjusted by a frequency converter. Furthermore, our screw press AL is available in three different sizes with screw diameters of 200, 315 and 500 mm.

The AKUPRESS BX LL-Ls for dewatering of finely structured materials is used where a clean liquid phase is the aim, or nutrient separation is essential. The ,X’ identifier represents our special patented torque control system used on all presses of the AKUPRESS BX line. The integrated sedimentation device is designed to further clean the press water and realized in a screw press for the first time. The pressure of the screw press results from the conical screw with adjusted flight heights. Throttling by hydraulically adjustable screen basket, adjustable plug length, and controlled torque are the main features. Our screw press AKUPRESS BX LL LS is available with different screw diameters of 400; 625; 800 and 1,000 mm. As it is a slow-running machine, energy consumption and wear are minimal.

Advantages:

  • Efficient and simple design
  • Easy maintenance
  • Special Flanged screw shaft
  • Interchangeable screen basket system
  • Optimized wear protection
  • Closed system
