Abstract
Abstract A mill for refining of cocoa, chocolate, paints, enamels and the like comprising an outer cylindric container, a rotor coaxially mounted within said container, independent means for imparting rotative motion to said outer cylindric container and to said rotor whereby the relative speeds of rotation may be adjusted commensurate with the properties of the particular material to be milled; said rotor being adapted to carry rolls or balls with the same being radially impelled against the inner face of the cylindric container during operation.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
214 words
A mill for grinding cocoa, chocolate, paints, enamels, and the like, comprising means defining an outer cylindrical enclosed casing having an upper end wall, a lower end wall, and an intervening side wall, a cylindrical rotor provided within said casing and having an upper end wall, a lower end wall, and an intervening side wall, said rotor and said casing being co-axial, said rotor having an outside diameter less than the inside diameter of said casing for developing an annular grinding volume therebetween, first means rotatably supporting said casing for rotation about its vertical axis, second means rotatably supporting said rotor for rotation about its vertical axis, first drive means operatively engaged to said casing for effecting rotation thereof, second drive means operatively engaged to said casing for effecting rotation thereof, means defining a raw material inlet at the upper end of said mill communicating with the upper end of said grinding volume, means defining a ground material outlet at the lower end of said mill communicating with the lower end of said grinding volume, and a plurality of grinding rollers disposed within said grinding volume being peripherally spaced about the outer face of the side wall of said rotor, said rollers having their longitudinal axes parallel to the vertical axis of said rotor.
Claim 2
Dependent Claim
214 words
A mill for grinding cocoa, chocolate, paints, enamels, and the like, comprising means defining an outer cylindrical enclosed casing having an upper end wall, a lower end wall, and an intervening side wall, a cylindrical rotor provided within said casing and having an upper end wall, a lower end wall, and an intervening side wall, said rotor and said casing being co-axial, said rotor having an outside diameter less than the inside diameter of said casing for developing an annular grinding volume therebetween, first means rotatably supporting said casing for rotation about its vertical axis, second means rotatably supporting said rotor for rotation about its vertical axis, first drive means operatively engaged to said casing for effecting rotation thereof, second drive means operatively engaged to said casing for effecting rotation thereof, means defining a raw material inlet at the upper end of said mill communicating with the upper end of said grinding volume, means defining a ground material outlet at the lower end of said mill communicating with the lower end of said grinding volume, and a plurality of grinding rollers disposed within said grinding volume being peripherally spaced about the outer face of the side wall of said rotor, said rollers having their longitudinal axes parallel to the vertical axis of said rotor.
Claim 3
Dependent Claim
41 words
A mill as defined in claim 1 and further characterized by speed varying means operatively connected to each of said first and second drive means for providing a differential in the relative rates of rotation of said casing and said rotor.
Claim 4
Dependent Claim
23 words
A mill as defined in claim 1 and further characterized by means causing said casing and rotor to rotate in the said direction.
Claim 5
Dependent Claim
23 words
A mill as defined in claim 1 and further characterized by means causing rotation of said casing and said rotor in opposite directions.
Claim 6
Dependent Claim
46 words
A mill as defined in claim 1 and further characterized by means provided on said rotor engaging said grinding elements for travel through said grinding volume upon rotation upon said rotor, the cross-section of said grinding elements being less than the cross-section of said grinding volume.
Claim 7
Dependent Claim
54 words
A mill as defined in claim 5 and further characterized by said means engaging said grinding elements being bracket-like elements provided upon said rotor and slidably engaging the respective grinding elements whereby the latter upon rotation upon said rotor may move relatively with respect to said bracket-like elements under the influence of centrifugal force.
Claim 8
Dependent Claim
94 words
A mill as defined in claim 5 and further characterized by said means engaging said grinding elements comprising bracket-like elements provided at the upper and lower ends of said rotor for extension radially outwardly thereof within said grinding volume, said bracket-like elements having recesses opening toward said casing, said recesses receiving portions of said grinding elements, said recesses being of slightly greater cross-sectional extent than the received portions of said grinding elements whereby the latter upon rotation of said rotor, under the influence of centrifugal force, will move within said recesses toward said casing.
Claim 9
Dependent Claim
60 words
A mill as defined in claim 7 and further characterized by the portions of said grinding elements received within said recesses of said bracket-like elements being of relatively reduced cross-section than the adjacent portions of said grinding elements for maintaining same against vertical displacement, said bracket-like elements having their outer edges terminating spacedly from the inner face of said casing.
Claim 10
Dependent Claim
48 words
A mill as defined in claim 8 and further characterized by said grinding elements being elongated rollers having their longitudinal axes parallel to the vertical axis of said rotor and being of like extent whereby grinding action is brought about within the full extent of said grinding volume.
Claim 11
Dependent Claim
82 words
A mill as defined in claim 1 and further characterized by said rotor upper end wall being located spacedly downwardly from said casing upper end wall to define a chamber of said raw material inlet means, the lower end wall of said rotor being located spacedly upwardly of said lower end wall of said casing to define a compartment of said ground material outlet means, said chamber and said compartment respectively communicating with the upper and lower ends of said grinding volume.
Claim 12
Dependent Claim
122 words
A mill as defined in claim 1 and further characterized by said first rotatable supporting means comprising upper and lower hubs projecting respectively from the upper and lower end walls of said casing, first bearing means journaling said casing upper hub, second bearing means journaling said casing lower hub, said casing first and second hubs being hollow, said second means rotatable supporting said rotor comprising a rotor upper hub projecting from the upper wall of said rotor into said casing upper hub, said rotor having a lower hub extending from its lower end wall into said casing lower hub, means provided within said casing upper and lower end hubs for rotatably supporting the received portions of said rotor upper and lower hubs.
Claim 13
Dependent Claim
165 words
A mill as defined in claim 11 and further characterized by means defining a raw material inlet comprising said rotor upper hub having a co-axial inlet passage, means connecting said passage at its rotor-remote end with a supply of raw material to be ground, said rotor upper end wall being spaced from the casing upper end wall to define an inlet chamber communicating with the upper end of said grinding volume, conduit means formed in said rotor upper hub and interconnecting said inlet passage and said inlet chamber, said means defining a ground material outlet comprising said rotor lower end wall being spaced frOm said casing lower end wall to define an outlet chamber communicating with the lower end of said grinding volume, said lower hub having a co-axial outlet passage, means connecting the lower end of said outlet passage to a point of disposition for ground material, conduit-forming means provided in said rotor lower hub for interconnecting said outlet passage and said outlet chamber.
