Abstract
Abstract An improved magnetic separator for effecting high efficiency collection of magnetics contained in solution and slurries. The separator comprises an enclosed magnet space having inlet and outlet ports for flowing therethrough of the slurry to be treated, a porous ferromagnetic material contained in the space, and means to establish in the space a magnetic field by a closed magnetic circuit, the lines of force of which are substantially all contained within the said magnet space.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
143 words
A magnetic separator for removing magnetics from clay slurries or the like passed therethrough comprising in combination: an enclosed magnet space defined by a hollow cannister, the walls of which comprise a non-magnetic material, said cannister being packed with porous ferromagnetic material throughout selected from the group consisting of steel wool, stainless steel wool, and porous ferrites, said cannister being provided with inlet and outlet ports at respectively opposite ends thereof for flow-through of the said slurry; and electro-magnetic means for establishing within said space a magnetic field defined by a closed magnetic circuit, the lines of force of which are substantially all contained within said enclosed space, said means for establishing said magnetic field comprising a coil mounted within said cannister and surrounded by said ferromagnetic material, whereby the current provided to said coil effects said magnetic field contained within said cannister.
Claim 2
Dependent Claim
143 words
A magnetic separator for removing magnetics from clay slurries or the like passed therethrough comprising in combination: an enclosed magnet space defined by a hollow cannister, the walls of which comprise a non-magnetic material, said cannister being packed with porous ferromagnetic material throughout selected from the group consisting of steel wool, stainless steel wool, and porous ferrites, said cannister being provided with inlet and outlet ports at respectively opposite ends thereof for flow-through of the said slurry; and electro-magnetic means for establishing within said space a magnetic field defined by a closed magnetic circuit, the lines of force of which are substantially all contained within said enclosed space, said means for establishing said magnetic field comprising a coil mounted within said cannister and surrounded by said ferromagnetic material, whereby the current provided to said coil effects said magnetic field contained within said cannister.
Claim 3
Dependent Claim
160 words
A magnetic separator for removing magnetics from clay slurries or the like passed therethrough comprising in combination: an enclosed magnet space comprising a hollow toroidal body packed with ferromagnetic material and having inlet and outlet ports for passing said slurry through said space; and electro-magnetic means for establishing within said space; a magnetic field defined by a closed magnetic circuit the lines of force of which are substantially all contained within said enclosed space, said means to establish said magnetic field comprising a coil wrapped about said toroid, whereby current supplied to said coil effects a magnetic field circuitously about the interior of said toroid; said toroid includes a transverse baffle and inlet and outlet ports respectively connected to the volume of said toroid at opposite sides of said baffle, whereby said slurry may be flowed through the entire volume of said toroid by passing said slurry into said inlet port, about said toroid body, and out said outlet port.
Claim 4
Dependent Claim
160 words
A magnetic separator for removing magnetics from clay slurries or the like passed therethrough comprising in combination: an enclosed magnet space comprising a hollow toroidal body packed with ferromagnetic material and having inlet and outlet ports for passing said slurry through said space; and electro-magnetic means for establishing within said space; a magnetic field defined by a closed magnetic circuit the lines of force of which are substantially all contained within said enclosed space, said means to establish said magnetic field comprising a coil wrapped about said toroid, whereby current supplied to said coil effects a magnetic field circuitously about the interior of said toroid; said toroid includes a transverse baffle and inlet and outlet ports respectively connected to the volume of said toroid at opposite sides of said baffle, whereby said slurry may be flowed through the entire volume of said toroid by passing said slurry into said inlet port, about said toroid body, and out said outlet port.
Claim 5
Dependent Claim
119 words
A magnetic separator for removing magnetics from clay slurries or the like passed therethrough comprising in combination: an enclosed magnet space comprising a hollow toroidal body packed with ferromagnetic material and having inlet and outlet ports for passing said slurry through said space; and electro-magnetic means for establishing within said space; a magnetic field defined by a closed magnetic circuit the lines of force of which are substantially all contained within said enclosed space, said means to establish said magnetic field comprising a coil wrapped about said toroid, whereby current supplied to said coil effects a magnet field circuitously about the interior of said toroid; said coil is enclosed within a second concentric toroidal body packed with ferromagnetic material.
Claim 6
