Abstract
Described is a roller mill (1) for grinding particulate material such as cement raw materials, cement clinker and similar materials, said roller mill (1) comprising a housing (3) which surrounds a grinding table (7) which is rotatable about a vertical axis (5), said grinding table being supported via a support (9) by a machine foundation (11), at least one roller (13) rotatable about a substantially stationary axis (12), said roller being configured for interaction with the grinding table (7) and an electric motor (15), which comprises a rotor (16) which is firmly connected to the grinding table (7) and a stator (17). The roller mill is peculiar in that the stator (17) constitutes an integral part of the support (9) for the grinding table (7), so that at least some of the load imposed by the at least one roller (13) on the grinding table (7) is transmitted via the stator (17) to the machine foundation (11).
