CHICAGO — Gneuss Inc. (Booth N4456) of Matthews, N.C., is showing the latest version of its filtration systems based on rotary technology. 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, and 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, the company said.
Contaminated screens, cleaned with high-pressure back-flushing in a closed system, can be used as many as 80 times. 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 0.5-2 percent material loss.
