粉砕装置及び粉砕装置の制御方法

Japanese Patent JP7080970

B2

The objective of the present invention is to operate a crushing device appropriately even if a crushing unit changes over time. A mill (1) is provided with: a crushing unit (30) for crushing coal by sandwiching coal between an upper surface of a crushing rotary table (35) and a crushing roller (36); a tension rod (39) for imparting a pressing load to the crushing roller (36) in a direction toward the upper surface of the crushing rotary table (35); a load deriving unit for deriving a load factor of the mill (1) at the present time; a performance value measuring unit for measuring a performance value of the mill (1) at the present time; a performance value deriving unit for deriving the performance value of the mill (1) at a reference time; and a control device (15) for changing a parameter affecting the performance value of the crushing device in such a way that the performance value of the mill (1) at the present time, measured by the performance value measuring unit, approaches the performance value of the mill (1) at the reference time, derived by the performance value deriving unit.
