Fixation device for lifters of a rotary drum cooler used in the cement industry

摘要

The lifters (10) are in the form of an arc. They are made up of two curved articulated sections (12,14) and destined to be fixed by their bases (24,26) on some fixing supports (18) integral with the inner face of a cylindrical sleeve (16) forming the wall of the cooler. The fixing of these lifters (10) on the supports (18) incorporates at least one dovetail fixing system and is realized by longitudinal sliding of the lifters on the supports which includes a thrust block (34) for wedging and positioning the lifters in the sense of progression of the clinker.
