Process for manufacturing a mill roll, especially for a sugar cane grinding mill, and roll obtained by this process

摘要

The invention relates to the manufacture of a cylinder, in particular for a rod mill, of the type in which the outer surface comprises circular grooves (11) of triangular cross section, the bottom of each groove (11) communicating with longitudinal channels (6) formed in the cylinder. In order to simplify manufacture, plugs (8) are inserted into radial channels (7) of the cylinder before executing the grooves (11) which cut the plugs (8) in which circular grooves (12) are then made. communicating the grooves (11) with the longitudinal channels (6).
