METHOD AND AN ARRANGEMENT FOR DETERMINING A DEGREE OF FULLNESS OF A LARGE GRINDING MILL DRUM, AND LARGE GRINDING MILL DRUM

摘要

The present invention relates to the field of mineral and metallurgical processes, to disintegrating in general and to disintegrating by tumbling mills, and more particularly to a method and arrangement for determining a degree of fullness of a large grinding mill drum, and to a large grinding mill drum. An arrangement for determining a degree of fullness of a large grinding mill drum according to the present invention has a sensor arrangement (13), (18), (28), (29), (30) attached to at least one lifting bar bolt (7) of an at least one lifting bar (5) of the grinding mill, said sensor arrangement (13), (18), (28), (29), (30) having an at least one force transducer (9), (25) attached to said at least one lifting bar bolt (7). With the help of the measurement arrangement according to the present invention more reliable measurement data can be provided for the determination of the degree of fullness of a large grinding mill drum.
