For process-related reasons, approximately 20% of all screening and discharge chutes are suspended beneath material silos or dosing hoppers. For these applications, ROSTA’s HS-type vibration elements offer an ideal solution, as they allow the screening machine to be suspended directly from the silo or hopper - without the need for complex yoke or intermediate structures. This not only reduces installation effort but also minimizes space requirements in confined plant layouts. The latest HS suspensions feature a specially optimized guide arm geometry that is consistently designed for tensile loads. Under ideal operating conditions, this reduces the suspension’s natural frequency from approximately 5.5 Hz to just about 3.5 Hz. This significant frequency advantage enables an isolation efficiency of over 97% and ensures exceptionally smooth, low-vibration operation - even with varying loads or demanding process conditions.
