Abstract
A tube mill with a cylindrical jacket (1) terminating at each end in a conical wall (2). The wall merges into a neck (3). A tube (6) is accommodated at a radial interval in a stationary milling-stock intake-and-outlet housing (5). The tube is attached to the neck. The tube is surrounded by a feed screw (12). The screw's threads (13) are loosely attached to the tube. The screw is connected to a shaft (9). The shaft is mounted in a bearing (18) outside the mill. The object is to improve the suspension of the feed screw to the extent that the bearing will be able to accommodate eccentric rotation by, and sudden and uncontrolled stresses on, the screw along with axial displacements of the shaft. The housing (19) for the bearing is accordingly surrounded at a radial interval by a continuous ring (22). The housing rests against the ring by way of several tensioned springs (23) uniformly distributed around the circumference of the housing.
