PROBLEM TO BE SOLVED: To solve such the problem that the existing pulverizing mill is loaded with an object to be pulverized with free-fall of self-weight, especially, when the object to be pulverized falls in a lower part of an introduction part at startup, load on drive power causes wide variation in granularity of pulverization and a difference in color of the object to be pulverized after pulverized.SOLUTION: In a pulverizing mill for pulverizing with a fixed upper mortar and a rotating lower mortar, first means is provided with a flow rate adjustment tool at a loading part provided at the upper mortar.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】 従来の粉砕機は、被粉砕物の自重による自然落下により投入がおこなわれる。特に起動時に導入部の下方に被粉砕物が落下すると、動力に負担がかかり、粉砕の粒度のばらつきが大きく、粉砕後の被粉砕物の色彩に差が出る。【解決手段】本発明の第1手段は、固定された上臼と回転する下臼とにより粉砕する粉砕機において、上臼に備えられた投入部に流量調整具を設ける。【選択図】図1
