Definitions

  • 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.
  • ball mill which consists of a cylindric container wherein metal or ceramic balls are loosely placed.
  • an object of this invention consists in the provision of a mill wherein the pressure and rotary speed of milling elements can be adjusted at will.
  • a further object of this invention is the provision of a mill which, in addition to the above stated feature, can be continuously operated.
  • a ball or roller mill for the refining of cocoa, chocolate, paints, enamels and like products, consisting of an outer cylindric container. within which a ball or rolls-supporting rotor is coaxially fitted, with the provision of suitable means through which rotary motions can be independently imparted to both suitably designed outer cylindric container and inner rotor.
  • FIG. 1 is an axial section of mill, and; FIG. 2 is a section taken on the line II-II of FIG. 1.
  • Said frame A comprises a base 1, wherefrom a vertical column 2 extends, being said column designed in such a manner as to allow two cantilever supporting arms 3 and 4 to be fitted thereon, the supporting arm being secured to lower end of column, while the supporting arm 4 extends from the top of said column 2.
  • cantilever arms 3 and 4 Supported by the outer ends of cantilever arms 3 and 4 is the proper ball or roller mill B.
  • said mill B comprises an outer cylindric container 5, having upper and lower hubs 6,7, respectively, which are housed in suitable roller bearings 8,9, respectively, with which the outer ends of supporting arms 3 and 4 are fitted.
  • the cylindric container 5 can be turned about its own axis by a motor 10 which drives a pulley 11 or other similar transmission means keyed to lower hub 7 of cylindric container 5.
  • a speed variator such as a gear box indicated at 10', is provided between the motor 10 and the pulley 11, in order to permit adjustment at will of the rotary speed of cylindric container 5.
  • suitable conventional means can be conveniently provided to lock, when required, the cylindric container 5 against any rotary motion.
  • a rotor 12 Coaxially fitted inside of cylindric container 5 is a rotor 12, carrying a plurality of milling rolls 13 on its outer surface, said rolls being accommodated in recesses 14 formed on rotor 12 in such a manner as to be radially impelled against the inner face of cylindric container 5 while the rotor is revolving.
  • said milling rolls 13, being axially parallel to rotor 12, are solid, but obviously the same might comprise a plurality of relatively shorter rolls, having different shapes and being supported at a number of points; or, if desired, balls can be utilized instead of said rolls.
  • Said rotor 12 is also provided with upper and lower hubs 15,16, respectively, which are engaged within the hubs 6, 7, respectively, of cylindric container 5, wherein the same are supported by roller bearings 18 and by plain bearings 19.
  • a rotary motion can be imparted to rotor 12 by a motor 20, which a belt transmission indicated'at 21, or the like, and a pulley 22 fastened to lower hub 16 of rotor 12.
  • a conventional speed variator such as a gear box indicated at 20 is provided between said motor 20 and pulley 22.
  • the material to be comminuted is fed by a pump or the like (now shown) through a duct 23, which is secured to upper supporting arm 4, and through a passage 24, as formed in hub 15 of rotor 12, to the interior of cylindric container 5 of mill B. Owing to rotation of rotor 12, and thus of the associated upper hub wherein the passage 24 is formed, the fed material is radially projected against the inner face of cylindric container 5.
  • Said passage 25 is connected to an outlet pipe 26 which is suitably connected to a suction pump (not shown) or the like.
  • both ends of rolls 13, as fitted around rotor 12, are seated within expressly provided recesses 14, whereby said rolls 13 are allowed to move radially when rotor 12 is driven by motor 20.
  • mill B For the particular properties of the material to be comminuted, it is merely requisite to adjust the speed of rotation of rotor 12 and of cylindric container 5, that is, by adjusting the RPM of rotor 12, the pressure exerted by rolls 13 against the inner face of cylindric container is correspondingly commensurately modified or controlled and thus against the material that is flowing downwardly threalong. While by adjusting the RPM of cylindric container 5, the rotary speed of milling rolls 13 can be increased. This is particularly advantageous because by keeping the RPM of rotor 12 unchanged, and thus with a preset working pressure, the rotary speed of rolls 13 may be increased by increasing the RPM of cylindric container 5 without, however, raising the working pressure of said rolls 13.
  • 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 roller
  • 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 crosssectional 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.
  • said chamber and said compartment respectively communicating with the upper and lower ends 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.
