FIELD: machine building. ^ SUBSTANCE: built-in elements are arranged inside drum 5 revolving about its central axis to mix and transfer loose material in blowing tempering fluid from drum inlet to outlet. Proposed invention consists in that several thrust rings 7 are arranged between said built-in elements and drum to take up static load and compensate for compression and extension stresses and jointed with said elements and/or their frames 14 and drum 5 with geometrical closure. Method of making drum 5 or drum segment for loose material drier consists in placing several thrust rings 7 to be arranged between said built-in elements and drum to take up static load and compensate for compression and extension stresses and jointed with said elements and/or their frames 14 and drum 5 with geometrical closure, Said built-in elements are mounted two support frames 14. Aforesaid thrust rings 7 are mounted on all sides of built-in element modules, directed outward. Built-in element module with elastic thrust rings 7 is fitted inside drum 5 or drum segment and locked therein by wedges or welding. Said rings are jointed with drum or drum segment with geometrical closure. ^ EFFECT: simplified design, lower costs. ^ 16 cl, 5 dwg |
