Comminution machine with a fixed anvil and rotating hammer blow iron (for example, hammer mills or a shredder)

摘要

This invention relates to a comminution machine with a fixed anvil and rotating hammer blow iron. In the case of such machines is the problem that, in the case of wear of the hammer heads to the hammer blow iron always the entire hammer blow iron must be replaced, if a constant quality of the comminuted material would like to reach. This is very expensive. The invention proposes, in the pivot pin for the hammer blow iron by a cylindrical, eccentrically, in relation to the distance from the anvil, in a light piece to guide bore provided. This insert has at its two ends of side plates of different thickness, so that by turning of the insert piece by 180° of the distance between the hammer head and the anvil can be varied. A hammer head is excessively worn, the insert piece can then removed and installed again pivoted about 180° are. The gap between the anvil and the hammer head can thus be regulated constant.
