ABSTRACT:
This invention relates to a wear means, which is arranged within a rotary drum barker as a wear protection of the drum mantle and is connected with this by means of a bolt joint. In rotary drum barkers the regions, where discharge openings for the bark are arranged, are subjected to a heavy wear. Therefore the wear means of the invention are preferably arranged in these areas. What characterizes the wear means of the invention is that it includes a wear body (4) of wear-resistant rubber and a prestressing means (13) which is connected to the wear body (4) so that it absorbs forces. Moreover, the wear means has a sleeve-shaped central portion (15) in connection with the prestressing means (13), the central portion (15) extending into a hole (17) in the drum mantle (1) of a bolt (6) included in the bolt joint and surrounding this.
