Abstract
A roller mill for grinding particulate material such as cement raw materials, cement clinker and similar materials includes a mill housing, a substantially horizontal and stationary grinding table, and a number of rollers each rotating about a roller shaft which is connected to a rotatable vertical shaft centrally positioned relative to the stationary grinding table. The rollers are configured for interactive operation with the grinding table. The grinding table is stationary. The roller mill also includes at least one first device utilized for introducing gases into the mill housing and at least one second device for continuously diverting ground material suspended in gases out of the mill housing. As a consequence hereof, the process for the roller mill with a stationary grinding table will be continuous and the diameter of the grinding table will not be subject to limitations.
