Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
106 words
In a crusher having a frame, a crushing head mounted within said frame for gyratory movement and free independent rotation, means for positively gyrating said crushing head, and a crushing concave mounted on said frame and cooperable with said crushing head to form an annular crushing zone; an upwardly open materialreceiving container mounted on said crushing head for gyratory and rotational movement therewith, said container having a sidewall converging inwardly toward its upper opening, said container having a series of circumferentially spaced discharge ports in the said converging sidewall thereof, and means of feeding material to be processed to said container above the upper opening therein.
Claim 2
Dependent Claim
106 words
In a crusher having a frame, a crushing head mounted within said frame for gyratory movement and free independent rotation, means for positively gyrating said crushing head, and a crushing concave mounted on said frame and cooperable with said crushing head to form an annular crushing zone; an upwardly open materialreceiving container mounted on said crushing head for gyratory and rotational movement therewith, said container having a sidewall converging inwardly toward its upper opening, said container having a series of circumferentially spaced discharge ports in the said converging sidewall thereof, and means of feeding material to be processed to said container above the upper opening therein.
