New screw press from Voith: high dewatering performance and low energy consumption, with minimum maintenance required
The InfiltraScrewpress boasts a design that is more than ten times stiffer than comparable machines, complementing its low center of gravity. This ensures the machine’s very tight tolerances over the entire operation cycle, allowing high dewatering performance and minimal fiber loss to be achieved. It is equipped with a double-thread press screw. The fiber suspension is fed into the screw press at a stock consistency of 8 – 12 % and is then transported by the press screw in axial direction. The suspension is thickened by the constricting volumes between press screw and screen baskets. Excess water is discharged via the screen baskets. The filtrate can thus be pressed out of the suspension and discharged via the screen baskets of the new SplitScreen screen elements. The remaining pulp is conveyed at a stock consistency of around 30% via the outlet of the screw press to the InfibraHeater quick heating screw.
The double-thread design of the screw press provides a continuous stock discharge to the InfibraDisp disperser, resulting in a reduction of the energy consumption in downstream processes. Together with a special protective coating, a further positive effect of the even stock flow is an extended service life and low maintenance outlay.
The SplitScreen screen elements feature improved dewatering performance and markedly greater ease of maintenance. Its special design allows quick replacement of the split screen plates without time-consuming disassembly of the entire screen element. The SplitScreen screen element is used in the new screw press, but can also be installed into existing screw presses as part of a rebuild package.
Voith’s BlueLine range for the stock preparation impresses with its low consumption of energy, fibers and water.
