Energy-efficient screening in stock preparation
The flow-optimized machine housing contributes to the efficient screening process of IntegraScreen in stock preparation.
Screening systems are used in various phases of stock preparation and papermaking for all kinds of furnish. The flow-optimized machine housing of IntegraScreen generates constant flow and pressure conditions around the basket. As a result, the reduced reject rate in combination with the high-quality Voith MultiFoil rotor and C-bar screening basket lead to high sticky removal efficiencies. Therewith higher runability of the paper machine as well as increased paper quality could be achieved. In addition, the high-quality screening equipment reduces the maintenance costs.
The improved machine housing makes possible the discharge of the light reject via the standard reject pipe. This saves investment cost for piping, valves, pump and instrumentation as well as energy costs.
The flow principle from the bottom to the top enables an integration of the reject recirculation into the machine, preferably at the final stage. Together with the additional reject dilution, simplified by the up-flow principle, the thickening of the reject will be reduced. Thus, clogging caused by to high thickening will be avoided. Furthermore, the lower reject consistency leads to a reduction of losses.
