Arrangement of the working gap of a crushing machine having a horizontally disposed hammer crusher rotor

In an arrangement including a working gap of a crushing machine having a housing in which is disposed a hammer crusher rotor including hammers thereon describing a striking circle via a horizontally disposed shaft on which said rotor is rotatably mounted;

• said working gap being disposed between the striking circle described by the hammers of said rotor as the latter rotates, and a bottom, trough-like inner housing surface that faces said rotor;
• said housing having an outlet for passage of material that has been comminuted and reduced in size by the hammers of said rotor, with said outlet extending tangential relative to said rotor;
• said housing also having an inlet that is provided with an anvil, with said inlet for material extending approximately radially relative to said rotor;
• the improvement therewith wherein an entire width of said working gap, when viewed in the direction of rotation of said hammer crusher rotor, is crescent-shaped in a path extending from said anvil at said inlet to said tangential outlet;
• support housing means for said shaft of said rotor;
• for the purpose of changing the size of said crescent-shaped working gap, the position of said support housing means is alterable relative to at least one of said anvil and said bottom, trough-like inner surface of said housing;
• support bracket means for said support housing means, and also, for the purpose of changing the height of said support housing means, spacers that can be selectively inserted and removed from between said support housing means and said support bracket means to effect vertical alteration of the position of said support housing means and hence of said rotor shaft.
