In connection with a bilateral project sponsored by BMFT "utilization of lignocellulose for the manufacture of board-type materials" between the Fraunhofer-Institute for Wood Research (WKI) and the Chinese Research Institute for Wood Industry (CRIWI), WKI took over amongst others the task to project a plant for the manufacture of gypsum-bonded particleboards according to the semi-dry process. Basis on the assessment of the requierements of the raw material has been an extensive investigation on Chinese raw materials which has been carried out by a visiting scientist from the People's Republic of China during his activities in the WKI. The required capacities have been calculated based on the project data. The entire production plant can be divided into the following categories heat production, binder calcination and board manufacture. In accordance with the related basic operations are described the technology and the projected plant technique including the required measures for the quality assurance.
