ABSTRACT:
A grinding clearance adjustment device for milling roller frames is disclosed, in which a casing contains two grinding rollers, one of which is constructed as a pivotable loose roller. Adjustment members, for the rollers are provided, as well as a device for the automatic setting of the grinding clearance by means of a remotely controllable drive motor, the latter being coupled to the adjustment members via transmission means. The motor operates through a clutch. In the preferred embodiment, the adjustment members are constructed as a first closed standard component, which has a lever-transmitted setting part with a longer and a shorter lever arm and which is laterally positioned in the vicinity of the grinding rollers. The drive motor and clutch are constructed as a second closed standard component, which is spaced from the first standard component, and the adjustment forces derived from the drive motor are coupled to the longer lever arm of setting part. In addition, the adjustment members are provided with a manual setting means which can be utilized simultaneously with the automatic, motor adjustment.
