About JOEST
Jöst GmbH + Co. KG (JOEST) has been developing and manufacturing vibrating machines and systems in Germany for over 100 years for conveying, dosing, screening, classifying, sorting, separating, cooling, drying and thermal treatment of bulk solids. The portfolio ranges from vibrating troughs, spiral conveyors and casting coolers to circular vibrating screens, linear vibrating screens, flip-flow screens (OSCILLA) and zig-zag classifiers, plus fluidized bed systems, shakeout troughs, compaction tables, crushers and ball mills – as individual machines or complete system solutions. The offering is complemented by in-house drive technology (magnetic drives, resonance exciters, eccentric motors, thyristor controls) as well as automation and digital solutions (J-SEN 4.0, J-MOTION, J-WATCH). Manufacturing takes place with a high level of in-house production depth at the headquarters in Dülmen-Buldern; maintenance, inspection, spare parts supply and operator training (JOEST VibeWorks) are also part of the service offering. Customers come from industries such as foundry, recycling, mining & minerals, chemicals, steel, food and feed. With GOESSLING (since 2019) and MOGENSEN (since 2024) and twelve subsidiaries on four continents, the JOEST group is active worldwide on five continents.
