Abstract: A roller mill (1) for grinding particulate material such as cement raw materials, cement clinker and similar materials, said roller mill (1) comprising a mill housing (2) enclosing a grinding (3) table and a set of rollers rotatable about a vertical shaft (4), said set of rollers being configured for interactive operation with the grinding table (3) and comprising a number of rollers (5) each rotating about a roller shaft (6) which is connected to the vertical shaft (4) via a hinged connection (7) with a centre of rotation (8) which allows a free circular movement of the roller (5) in upward and downward direction in a plane comprising the centreline (9) of the roller shaft (6), said centre of rotation (8) of the hinged connection (7) in a vertical plane is located under the centreline (9) of the roller shaft (6). The roller mill is peculiar in that the grinding table (3) is rotatable about the vertical shaft (4) and in that the roller mill (1) comprises means (10,11) for introducing gases into the mill housing (2) and means (12) allowing for continuously diverting ground material suspended in gases out of the mill housing (2). It is hereby obtained that the grinding process is performed continuously as the material fed to the grinding table is transported across the grinding table, by means of the centrifugal forces to which the material is subjected due to the rotation of the grinding table, to the rollers where it is ground and subsequently suspended in the gas introduced in the mill housing, whereafter the ground material in suspended form is diverted through an outlet connected to the mill housing.

Abstract: A description is given of a roller mill (1) for grinding particulate material such as cement raw materials, cement clinker and similar materials. The roller mill comprises a force device (8) for at least partial absorption of an axial force originating at least from the roller and acting in the longitudinal direction of the roller shaft (6). Said force device (8) comprising a first part (9) and a second part (10), where the first and second part (9, 10) comprise opposing pressure surfaces (9a, 10a) which both forming between them a compartment (11) where the pressure surface (9a) on the first part is provided so that it is oriented in the opposite direction to the axial force acting in the longitudinal direction of the roller shaft, and means (12) for introducing a pressurized viscous medium into the compartment between the opposing pressure surfaces. Hereby is obtained an efficient and adjustable force device for relieving the axial force exerted on the roller bearing which may thus be constituted by commercially available bearings.

Abstract: A description is provided of a roller mill (1) for grinding particulate material such as cement raw materials, cement clinker and similar materials, said roller mill (1) comprises a mill housing (2), a substantially horizontal grinding table (3) and a number of rollers (4) each rotating about a roller shaft (5) which is connected to a rotatably vertical shaft (6) centrally positioned relative to the grinding table (3) where the rollers (4) are configured for interactive operation with the grinding table (3). The roller mill is characterized in that the grinding table (3) is stationary and in that it (1) comprises means (8) for introducing gases into the mill housing (2) and means (7) for continuously diverting ground material suspended in gases out of the mill housing (2). As a consequence hereof, the process for a roller mill with a stationary grinding table will be continuous and the diameter of the grinding table will not be subject to limitations.

Abstract: A description is given of a roller mill for grinding particulate material, such as cement raw materials, cement clinker and similar materials, which roller mill comprises a grinding table (1) which is rotatable about a vertical axis (2), at least one roller set (3) comprising a shaft (4) and two rollers (5), which are rotatably mounted on the shaft (4), and two torque reaction arms (6) each of which are rotatably connected to the shaft (4) and frame (7) or foundation. The roller mill is peculiar in that the roller set (3) comprises a centering rod (8) extending substantially parallel to the roller shaft (4) and being at its one end rotatably connected to the roller shaft (4) and at its other end being rotatably connected to a machine element (4, 7) which is fixed or stationary in the longitudinal direction of the roller shaft. It is hereby obtained that the roller set is maintained in the longitudinal direction of the roller shaft so that the roller set will remain centered on the grinding table even after prolonged roller mill operation. This is ascribable to the negligible wear being incurred on the rotatable connections of the centering rod.
