Chip and turnings separator and crusher

In combination with a shredding and tearing crusher a device for separating chunk metal components from the intermeshed turnings and shavings of metal scrap resulting from machining operations whereby the turnings and shavings can be passed through the crusher free of chunk metal, said device having a generally horizontal receiving section, the crusher having bottom and sides;

• a horizontally elongated scrap receiving port in one of said sides and a plurality of crushing rolls including a pair of vertically spaced receiving and crushing rolls forming a horizontal scrap receiving path between them at said scrap receiving port;
• means to drive said rolls;
• the scrap receiving and crushing path between said rolls being so sized as to be suitable only for turnings and shavings;
• the improvement in said device comprising:
• said receiving section having a discharge end;
• a grate member in said receiving section immediately adjacent said scrap receiving port and means spaced from said grate and said rolls for pushing the metal scrap across said grate, said grate member having a plurality of parallel spaced elongated bars extending lengthwise of said receiving section and over which the scrap is pushed;
• said bars being spaced to retain said intermeshed turnings and to permit small chips and the chunk metal to pass between them the ends of said bars being so positioned with respect to said crushing rolls as to introduce said turnings generally horizontally into said scrap receiving path between the rolls.
