KPI-JCI, a division of Astec Mobile Screens, expects its new multi-frequency screen to revolutionize the screening industry. With the combination of both conventional and high-frequency screen movements integrated, the screen is able to maintain the higher production rates of a PEP screen at a lower angle, while handling higher moisture content materials. Coarser material requires more amplitude and less frequency, while finer material requires less amplitude and more frequency. The multi-frequency screen combines both theories. By working at a lower operating angle, the overall height of the screen is less — making it safer to work on and operate.
