Described is a roller mill (1) for grinding particulate material such as cement raw materials, cement clinker and similar materials, said roller mill(l) 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) .
L~invention concerne un broyeur à cylindres (1) servant à broyer des matières particulaires, telles que des matières premières pour ciment, du clinker et autres matières similaires. Le broyeur à rouleaux (1) comprend un carter (3) entourant une table de broyage (7) rotative autour d~un axe vertical (5), la table de broyage étant soutenue par un socle (11) par le biais d~un support (9) ; au moins un cylindre (13) rotatif autour d~un axe sensiblement fixe (12), ce cylindre étant configuré pour entrer en contact avec la table de broyage (7) ; et un moteur électrique (15) comprenant un rotor (16) solidaire de la table de broyage (7) et un stator (17). Le broyeur à cylindres est caractérisé en ce que le stator (17) fait partie intégrale du support (9) de la table de broyage (7), si bien qu~une partie au moins de la charge exercée par ledit au moins un cylindre (13) sur la table de broyage (7) est transférée au socle (11) par le biais du stator (17).
