Document Type and Number:
Japanese Patent JP2016159234
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a mortar which can suppress a variation in powder granularity generated by a difference in size of cast pulverization objects.SOLUTION: A mortar of this invention comprises a first mortar and a second mortar disposed by facing each other and gets a pulverization object pulverized with a shearing groove by the relative rotation of the first mortar 360 and the second mortar on the center axis, where the first mortar 360 includes a first grinding surface 360a, and the second mortar includes a second grinding surface disposed by facing the first grinding surface 360a, at least one of the first grinding surface 360a and the second grinding surface having a first region R11 provided with a first shearing groove 361 to be located at the center, a second region R12 provided with a second shearing groove 362 to encircle the first region R11, and a first annular flat part F11 provided between the first region R11 and the second region R12 so that the first shearing groove 361 may be parted from the second shearing groove 362.SELECTED DRAWING: Figure 14
