Screw press

The screw press thickens the pulp from 3% up to 35% consistency. As the pulp becomes thicker, it enters the heating zone with less water. Because of this, steam use drops, and the dispersing result improves. In the end, higher consistency means lower energy use and better pulp quality.

Conveyor

The Compact Dispersing System (CDS) is a non-pressurized system designed for efficient and space-saving pulp processing. Because of its open design, a conveyor can replace both the plug screw and the shredder, creating a more compact and energy-efficient solution for feeding the pre-heater.

Pre-heater

In the pre-heater, the pulp warms up to 90–120°C, depending on the raw material. At this point, wax, hot melts, and stickies melt and lose strength. As a result, these materials become softer and easier to remove during dispersing. This makes the process smoother and more efficient.

Infeeder

The infeeder moves the pulp from the pre-heater to the disperser. Its patented design prevents blocking and reduces energy use. Moreover, it ensures a steady flow for reliable operation.

Disperser

Inside the disperser, fibers pass through a narrow gap between rotating discs. Here, impurities break down into very small particles. The discs have a special devil-tooth pattern that is adjusted for each pulp type to protect the fibers. Furthermore, the operator can adjust the disc gap online with an accuracy of 0.01 mm for precise control.
