Abstract
Abstract The invention relates to a coil arrangement for a magnetic separator having a strong field, in which the solenoid coils are provided in the first part only of the length of the housing and a magnetic shunt is arranged between the first and second parts of the length of the housing. A considerable reduction in the coil weight is achieved by such a construction.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
69 words
In a magnetic separator having an annular housing formed of weak magnetic material and through which extends a channel having an inlet and an outlet, the improvement comprising at least one magnetic coil encircling said channel adjacent the inlet thereof, and a magnetic shunt between the inlet and the outlet of said channel, that portion of said channel between said outlet and said shunt being free of magnetic coils.
Claim 2
Dependent Claim
69 words
In a magnetic separator having an annular housing formed of weak magnetic material and through which extends a channel having an inlet and an outlet, the improvement comprising at least one magnetic coil encircling said channel adjacent the inlet thereof, and a magnetic shunt between the inlet and the outlet of said channel, that portion of said channel between said outlet and said shunt being free of magnetic coils.
Claim 3
Dependent Claim
22 words
A magnetic separator according to claim 1 including more than one magnetic coil between said inlet of said channel and said shunt.
Claim 4
Dependent Claim
17 words
A magnetic separator according to claim 2 wherein each of said magnetic coils is of uniform size.
Claim 5
Dependent Claim
24 words
A magnetic separator according to claim 2 wherein not more than two of said magnetic coils are positioned between said inlet and said shunt.
Claim 6
Dependent Claim
17 words
A magnetic separator according to claim 4 wherein each of said magnetic coils is of uniform size.
Claim 7
Dependent Claim
23 words
A magnetic separator according to claim 6 including means forming a cooling medium chamber in said housing between said shunt and said outlet.
Claim 8
Dependent Claim
15 words
