Grinding method for a ball drum mill, ball drum mill and mill lining

摘要

The invention relates to a grinding method for a bulb tube mill and a ball tube mill. According to the invention, provision is made to improve the material feeder and the frictional behavior in the drum longitudinal direction derfolgende balls aufeinan be subjected to substantially radial to the drum axis ver current relative movement in addition to their counter to the rotational direction of the drum taking place overturning a ge mutual by the balls raised in the radial direction or are lowered and returned to its original location. For this purpose, in the grinding plates (1) grooves (2) are provided with changing along the drum circumference depth.
