PRE-GRINDER OR PRE-SHREDDER

摘要

The present invention relates to a pre-grinder or pre-shredder of materials derived from all sources, with a view to shredding by means of hammer crushers or grinders, or the like. The pre-grinder or pre-shredder is characterized in that it is compact, adaptable, and essentially formed from at least one shredding tool (1) and at least one means (2) for driving said tool (1), the thus-formed assembly being directly mounted onto a frame (3), a feed chute, or another mounting via the drive means (2) or via a mounting for the latter. The invention is more specifically used for processing materials derived from all sources, particularly through shredding by means of hammer crushers or grinders, or the like. Said invention further relates to a compact, adaptable pre-grinder or pre-shredder.
