Abstract
A mill includes a first mill having a first grinding region, a second mill having a second grinding region opposed to the first grinding region and provided to be rotatable relatively to the first mill, and a heat radiation mechanism which is provided in at least one of the first mill and the second mill and radiates friction heat generated as a result of rotation of the first mill and the second mill relative to each other, and the heat radiation mechanism is provided in a portion except for the first grinding region and the second grinding region.
Claims19
A mill comprising:
- a first mill which has a first grinding region;
- a second mill which has a second grinding region opposed to the first grinding region and is provided to be rotatable relatively to the first mill;
- and
- a heat radiation mechanism which is provided in at least one of the first mill and the second mill and radiates friction heat generated as a result of rotation of the first mill and the second mill relative to each other,
- the heat radiation mechanism being provided in a portion except for the first grinding region and the second grinding region.
A milling machine comprising:
- a drive portion which generates driving force;
- a driving force transmission mechanism which transmits the driving force generated by the drive portion;
- and
- a milling unit attached to the driving force transmission mechanism,
- the milling unit including a rotation mechanism which rotates an upper mill and a lower mill relatively to each other,
- the driving force transmission mechanism including a power transmission portion which connects the drive portion and the rotation mechanism to each other and transmits the driving force to the rotation mechanism, and
- at least a part of the power transmission portion including a charging prevention member.
A mill comprising:
- an upper mill and a lower mill having a common central axis,
- the mill grating an object to be grated as a result of rotation of the upper mill and the lower mill around the central axis relative to each other,
- the upper mill including a first grinding surface,
- the lower mill including a second grinding surface arranged to be opposed to the first grinding surface,
- the second grinding surface having a recess portion provided to be recessed from a virtual plane with the virtual plane being defined as a reference, the virtual plane being a plane in parallel to a radial direction of the central axis and passing through a portion of the second grinding surface located at a highest position, and
- the first grinding surface having a projection portion, the projection portion being provided to project from the virtual plane toward the lower mill, having a shape corresponding to the recess portion, and fitting into at least a part of the recess portion.
16-17. (canceled)
A mill comprising an upper mill and a lower mill, the mill grating an object to be grated as a result of rotation of the upper mill and the lower mill relative to each other,
- the upper mill including a first grinding surface,
- the lower mill including a second grinding surface arranged to be opposed to the first grinding surface,
- each of the first grinding surface and the second grinding surface having a plurality of groove portions for grating an object to be grated, the plurality of groove portions being provided to have a height difference, and
- the plurality of groove portions being provided to have a height difference.
