At least one roller (5) is assigned a scraper (7). The scraper (7) has a blade (8) for scraping milling material from a roller surface (9) with a scraper edge (10) which extends over an entire length (L) of the blade (8), and comprises a holder (11) with a receiving region (12). The holder is arranged in the housing (2) so as to be tiltable about an axis (13) parallel to the roller axis. An elastic bearing (14) is arranged between the blade (8) and the receiving region (12).
