摘要：In a vertical mill, a mill table is supported in a housing by a support shaft center, which is along a vertical direction, in such a manner as to be driven and rotated, and above the mill table, a mill roller is rotatably supported by a first support shaft, and the mill roller is capable of rotating the mill table in such a manner that an external peripheral surface of the mill roller comes into contact with an upper surface of the mill table, and a support arm configured to support the first support shaft is swingably supported on the housing by a second support shaft, in such a manner that the mill roller can come close to or move away from the mill table, and a reaction force load giving device is provided that has a dumper filled with a magnetorheological fluid and magnetizes the magnetorheological fluid.

主权项：1. A vertical mill comprising: a housing having a hollow shape; a mill table rotatably supported in the housing by a support shaft center along a vertical direction; a mill roller provided above the mill table and rotatably supported by a first support shaft, the mill roller being capable of rotating with an external peripheral surface of the mill roller coming into contact with an upper surface of the mill table; a support arm for supporting the first support shaft, the support arm being swingably supported on the housing by a second support shaft with the external peripheral surface of the mill roller coming close to or moving away from the upper surface of the mill table; and a reaction force load giving device having a dumper filled with a magnetorheological fluid and magnetizing the magnetorheological fluid so as to give a reaction force load to the mill roller via the support arm, the reaction force load being given against a direction in which the mill roller moves away from the mill table.
