<p>A grinding mill requiring one or more new grinding balls (6) is adapte.d so that they can be passed into the mill through spider-guide apertures (30). The spider-guide apertures provide anchors for spider-guide mountings (18), by means of which a spider used to grip an upper grinding ring is restrained against rotation. There may be provided two mounting frames between the spider-guide mounting (18), and the mill. Frame (36) is secured to the mill and has a large opening, able to pass a grinding ball. Frame (38) is secured to frame (36) and has a smaller opening, and provides a mounting location for the spider-guide mounting (18).The arrangement means that mill disassembly and lifting then lowering, grinding balls is no longer needed.</p> |
