What Rhewum does
Rhewum is a German manufacturer of industrial vibrating screening machines founded in 1927 and headquartered in Remscheid, Germany. The company specializes in proprietary direct electromagnetic excitation technology, in which vibration is applied directly to the screen mesh via high-frequency rocker shaft movement rather than vibrating the entire machine frame, enabling accelerations up to 50g at the screen cloth with claimed power consumption reductions of up to factor 10 versus conventional oscillating screens (0.52-3.9 kW vs. 15-18 kW). Its product portfolio spans the RHEsono, RHEmoto, RHEfino, RHEsonox, and RHEhydra lines covering particle separation from 50 µm to 10 mm, alongside linear vibrating screens, double-frequency screeners, wet classification equipment, feeders, and conveyor systems.
Rhewum operates a sales-led B2B go-to-market focused on direct enterprise engagement with material testing, process analysis, and custom machine design at its Remscheid technical center. Revenue derives from custom-engineered capital equipment sales, spare parts (via the my.rhewum.com online shop), and professional services including commissioning, training, and retrofits. The company serves eight primary verticals — fertilizers, sugar and sweeteners, building materials, recycling, pharmaceuticals, mining and minerals, food, and chemicals — with named enterprise customers including Agropolychim AD, YARA, Indian Cane Power, Erawan Sugar Company, Zhejiang Huakang Pharmaceutical, SUEZ/Améthyst, and BK Giulini.
The company operates through wholly-owned subsidiaries RHEWUM America Inc. (Davie, Florida) and RHEWUM India Pvt Ltd. (Bengaluru), with regional channel partners (Balmac in Thailand) supporting Southeast Asia. Manufacturing is concentrated in Remscheid, where a 1,000+ photovoltaic module solar installation covering 3,800 m² of factory roof delivers 70% energy self-sufficiency. The company employs 101-250 people, is privately held with no disclosed external funding, and has emphasized sustainability commitments including EcoVadis Committed status (2026) and a transition to water-based coatings reducing VOC emissions by 78%.

Rhewum product offering
Product offeringCore offering
RHEWUM designs and manufactures custom-engineered vibrating screening machines and conveyor technology for industrial bulk material separation. Its core offering is direct-excitation screening equipment (RHEsono, RHEmoto, RHEfino, RHEsonox, RHEhydra) that applies vibration directly to the screen mesh rather than the machine frame, enabling precise separation from 50 µm to 10 mm with up to factor-10 lower power consumption than conventional oscillating screens. Each machine is tailored to the customer's specific material behavior, throughput, and cut-point requirements, supported by in-house material testing, process analysis, and after-sales services.
Product overview
Rhewum is a German manufacturer of industrial screening machines and conveyor technology with over 70 years of experience. The product portfolio centers on vibrating screening machines with direct excitation technology, including the RHEsono® (fine particles 100 µm-2 mm), RHEmoto® (medium particles 1-10 mm), RHEfino® (hybrid for multi-range), RHEsonox® (powder sieve ultra-fine to fine), and wet classification equipment (RHEhydra®). The offering also includes linear vibrating screens, double-frequency screeners, and complete feeder/conveyor systems. Supporting tools include the ScreenSpector mobile app, MeshConverter, Machine Finder, and Screen Efficiency Calculator. All machines feature direct excitation technology where vibration is applied directly to the screen mesh rather than the entire frame, enabling high acceleration forces, energy efficiency, and static housing design.
