The invention pertains to a rotary grinding mill having a drum which is provided with a lining and at least one lifting device, and relates to an arrangement for registering wear on the lining and particularly on its lifting device. In order to provide an arrangement by means of which it is possible to register when the lifting device of the mill lining has been worn to at least a given, predetermined level of wear, it is suggested, among other things, that the lifting device (7) is fitted with at least one loop (15) whose radially inner end is located on a level which corresponds to the predetermined degree of wear on the lifting device (7) to be registered, and which forms part of a closed wear-indicating circuit (15, 19) which, immediately the loop is broken, delivers a signal which indicates the predetermined degree of wear to be registered. |
