1456716 Tube mills BARBER-GREENE CO 18 Sept 1974 [3 Dec 1973] 40622/74 Heading B2A A tube mill having internal lifters 3 and a dewatering perforate trummel at the dischange end has the drum driven by rubber tires T, Fig. 1, which are readily removable from their drive nuts. Mounting plates 12 Fig. 8 are secured to transverse beams 8 Fig. 2 and include semi-circular bearing adaptors 15 which are slipped into complementary recesses 16 in the adaptors 15. Bearing assemblies 10 set in the adaptors 15 and are held in place by slots 17. The assemblies include opposed tapered roller bearings 20, 21. Fig. 5 mounted on a rotatable drive shaft 24, which is driven by a motor E. To permit the tires T to be removed their mounting arrangement comprises double tire hubs 51, Fig. 5 keyed to the shaft 24 each hub shaving a flange 53. The tire rim 54 has a flange 55 bolted to the flange 53. The hub also has a smaller diameter second flange 63. Secured to this flange 63 is a segmental two part hub ring 70 of the same outer diameter as the flange 53. This permits a tire assembly, viz the tire T and its radial flange 55 to be interchanged. To replace tire T 2 , Fig. 5, adjacent tire T is first removed from the flange 70. Tire T 2 is then readily removable due to the difference in radial dimension. The shaft 24 is made in sections and thus is itself readily removable. Tire guide wheels 76, 77 bear against radially extending flanges 78, 79 fixed around the periphery of the drum and prevent the drum shifting axially.
