For decades, ROTAMILL designs and produces state-of-the-art solutions that set standards in the area of efficiency improvement and productivity enhancement.
Origin of ROTAMILL was a special technique of grinding sulfur. The engineer Bernhard Plath (from Siegen, Germany) developed and built his first plant after World War II. Core part of the plant was, and still is, a rotating impact mill. This mill consists of both syllable ROTA (abbreviation for rotation) and MILL.
Nowadays, ROTAMILL is a specialist for process plants in the range of exhaust air cleaning and waste heat recovery. With the know-how of the former Langbein & Engelbracht and the former Schrim Wärmetechnik, the knowledge of planning and construction of thermodynamic plants has been further enhanced.
Under the umbrella of the new ROTAMILL GmbH, we bundle the expert knowledge of the former Langbein & Engelbracht GmbH, the former Schirm Wärmetechnik GmbH and the process plant construction of the former ROTAMILL Anlagen-, Apparate- und Ventilatorenbau GmbH.
