The KROOSH multi-frequency screening technology has proven its efficiency many times and in many countries around the world. Below you will find some articles published by both academic institutions as well as the end-users each describing their experiences with KROOSH screeners.

Brief: In South African Republic the tests have been carried out which, according to Dr. Adrian Hinde, have shown that KROOSH technology improves screening efficiency by at least 400%. Another effect that Dr.Hinde notes is the absence of mesh clogging due to the multi-frequency screening technology.

Brief: F.W. Winter’s customer requires that the metal alloy powder’s particles be equal to or smaller than 325 mesh (44 microns). To produce the powder at the appropriate size, the company first reduces metal alloy to about 230 mesh (about 75 microns) using a mill. The company then prescreens the material using a single-deck screener with a 230-mesh screen. Particles larger than 230 mesh discharge from the screen’s top and are sent back to the mill for further size reduction. Particles smaller than 230 mesh pass through the screen and discharge into a 2,500-pound-capacity bottom-discharge hopper. Since using multi-frequency KROOSH technology, the company is able to feed the metal alloy powder to the screener about 6 times faster than it could to a screener with an ultrasonic unit. “We were able to increase the feedrate to the screener, and our yield percentage improved".

Brief: Multi-Frequency Vibration (MFV) deagglomerates particles by overcoming the interparticle adhesive forces by imparting G-forces above 100G: this allows the effective screening of sticky material, but also prevents bridging of fine material which results in screen blinding. Kroosh Technologies used to be a part of Virto-Cuccolini group therefore KROOSH screeners sometimes are known as X-Line screeners. At the chart 1 we can see Efficiency curves for Virto-Cuccolini X-Line (RS2310.1) versus two different flip-flow screens on South African coal. At the chart 3 we can see Efficiency of the Virto-Cuccolini RS2814.1 compared to the efficiency of a hydrosizer over a 30-day period at a silica mine in South Africa.
