CHICAGO — Gneuss Inc. of Matthews, N.C., showed the latest version of its filtration systems based on rotary technology at NPE 1997, held June 16-20 in Chicago.
The KSF 150x2 features a continuous and process-constant screen changer.
The active screen surface area is not reduced during a screen change, allowing process parameters to remain constant. With this technology, degraded material is not introduced into the melt flow, preserving the quality of the product.
This version includes simplified handling, disturbance-free and cost-saving features. The mechanical and control-technical simplification leads to a fully or semiautomatic process. Operating and maintaining the filtration system is reduced, because setting and adjustment work is unnecessary, according to the company.
Contaminated screens that are cleaned with high-pressure back-flushing in a closed system can be used as many as 80 times, according to Gneuss. Because of the indexing movement of the filter wheel along the purging slit, the screens are washed evenly in small segments.
The efficiency of the purging allows only one-half to 2 percent material loss, according to the company.
