Abstract
Abstract A mechanized system and processing method for refining gross raw scrap material, such as automobile bodies and frames, other larger objects such as refrigerators, and smaller pieces of scrap material of various shapes and sizes, to produce therefrom a fluent mass of particulate metal relatively free of nonmetallic refuse, and separated into ferrous and nonferrous portions, the ferrous portion so formed being in condition for direct use as raw material for steel-making operations.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
44 words
A system according to claim 1 wherein said ripper means includes an arm member mounted for oscillatory movement across the face of said densified mass discharging from said crusher means and carrying a plurality of spaced ripper teeth disposed to tear through said mass.
Claim 2
Dependent Claim
25 words
A system according to claim 1 including conveyor means for transferring said smaller pieces from the discharge of the ripper means to the shredding mill.
Claim 3
Dependent Claim
36 words
A system according to claim 1 including vacuum dust-collector means having one collector conduit communicating with the interior of said shredding mill and a second collector conduit disposed in dust-collecting relation to said shaker screen means.
Claim 4
Dependent Claim
65 words
A system according to claim 1 wherein saiD shredding mill includes: a. a rotor; b. a plurality of hammers swingably mounted about the periphery of the rotor and having relatively sharp toe portions projecting from the leading edges thereof; and c. breaker plates disposed adjacent the path of movement of said hammers against which said pieces are broken and shredded by impacts of said hammers.
Claim 5
Independent Claim
87 words
The method of refining raw ferrous-bearing scrap material, comprising: a. subjecting bulky raw scrap material to an initial crushing action to produce a densified mass therefrom; b. ripping the densified mass into smaller pieces while said mass is maintained under the crushing pressure; c. subjecting said smaller pieces to a shredding treatment operably to produce therefrom a fluent mass of relatively finely divided particulate material; d. separating nonmetallic refuse from metallic particles in the fluent mass; and e. separating said metallic particles into ferrous and nonferrous portions.
Claim 6
Dependent Claim
105 words
A process for the continuous production of presized high grade scrap metal from auto bodies and similar large bulky type material, including the steps of: a. subjecting the scrap charge to crushing pressure to compact the same into a densified mass of balelike configuration; b. systematically ripping the mass while subject to said crushing pressure into relatively large size pieces; c. dynamically disintegrating the relatively large size pieces to produce there from relatively small size scrap pieces which are of either predominantly ferrous or nonferrous metal composition; and d. separating the predominantly ferrous from nonferrous metal pieces; and conveying said pieces to separate storage areas.
