Abstract
The invention relates to a safety system ensuring availability of a milling or crushing plant with a roller grinding mill, which is provided in a combined plant, more particularly for the mill drying of cement raw material. For bringing about an almost 100% redundancy, in particular six milling rollers are provided. The roller grinding mill is designed in such a way that 80% of the full milling capacity can be provided in four-roller operation.
