What Riedhammer does

Riedhammer GmbH, headquartered in Nuremberg, Germany, is a privately held industrial kiln and furnace system manufacturer and a wholly-owned subsidiary of Italian conglomerate SACMI Group (4,000+ employees across 30+ countries). Founded in 1924, the company has delivered more than 10,000 kilns worldwide, including 700 battery kilns and 60+ rotary kilns specifically for lithium-ion battery powder production, and reports its 300th roller hearth kiln for the LIB sector. Its portfolio spans roller hearth kilns, rotary kilns, tunnel kilns, belt kilns, chamber kilns, dryers, and complete upstream/downstream process lines, addressing seven industrial verticals: lithium-ion battery materials, carbon (anodes/cathodes for aluminum and steel), technical ceramics, sanitaryware, refractory products, tableware, and advanced materials (including battery recycling pyrolysis systems for black mass recovery).

The company's core technology centers on high-temperature thermal processing with proprietary features such as hydrogen-ready kilns, a 100% electric roller kiln, atmosphere control systems, and integrated waste heat recovery for energy efficiency. Riedhammer generates revenue through hardware sales of custom-engineered plant solutions, recurring spare parts supply and worldwide warehousing, and professional services including inspection, maintenance, revamping/modernization, consulting, and remote-control support. Pricing is quote-based (not publicly disclosed) and distribution is conducted through direct enterprise sales, a global sales network leveraging SACMI's footprint, a Japan subsidiary (Riedhammer Japan Co. Ltd), and presence at major trade shows such as Ceramitec, Battery Show Europe, CIBF, and InterBattery. The company is led by Managing Directors Matthias Uhl and Stefano Lanzoni.
