Definitions

  • One of such novel means was a ball or pebble mill that essentially consists of a cylindric vessel, loosely filled with metal or ceramic balls or pebbles. A strong vibration was then imparted to said vessel, which resulted in an intensive hammering action exerted amongst the balls or pebbles. The product to be refined was pumped through the pebble filling, wherein it was finely comminuted.
  • This invention obviates the drawbacks of the heretofore known methods by the provision of a ball mill which, in addition to its manifest operating advantages, can be also installed at a reasonably low cost.
  • the mill for the refining of cocoa, chocolate, paints, lacquers, enamels and the like which is characterized in that it consists of a vertically extending, stationary outer cylindric casing, wherein an also cylindric rotor is revolvingly fitted.
  • Partitions are provided on the outer wall of said rotor to form means for supporting balls for rotation.
  • the halls are thus positively guided whereby to exert a comminuting action by rolling alone.
  • the partitions define a spiral path extending along the outer wall of the rotor.
  • FIG. I is a vertical axial section of the mill
  • FIG. 2 is a fragmentary elevation view of the rotor, the balls and the ball-guiding, rotor-carried projections;
  • FIG. 3 is a fragmentary vertical sectional view taken along the line 3-3 of FIG. 2;
  • FIG. 4 is a horizontal section of the structure shown in FIGS. 2 and 3.
  • 1 is the machine bed and 2 is the geared motor by which the RPM of a rotor 4 can be suitably adjusted.
  • 3 is the driven shaft of the rotor.
  • S are the projections formed along a spiral path on the outer rotor wall, and between which the balls are positively guided.
  • the double-walled cylindric casing 7 shows an intervening space 8, wherein a suitable fluid is circulated for heating or cooling the mill.
  • Said cavity wall is formed with ports 9 and 10 for the inlet and the outlet, respectively, of said fluid.
  • the product is fed to the mill by a pump 11 through a duct 12 and the inlet port 12a of casing 7; the ground product is discharged through the upper outlet port 13.
  • FIG. 1 The direction in which the heating or cooling fluid is circulated in FIG. 1 is illustrated by arrows f, and f in the inlet and outlet ports, respectively.
  • the direction of travel of product is indicated by the arrows f and f, also in the inlet and outlet ports, respectively.
  • FIGS. 2, 3 and 4 show how the balls 6 are positively guided by the band-shaped elements 5 (projections), i.e. partitions, extending along a spiral path and which design is clearly shown, above all in FIG. 4.
  • the balls are loose fitted in their seats and are freely movable in a radial direction.
  • the balls When the rotor is started, the balls are urged by centrifugal force agains the casing inner wall, rolling simultaneously thereon, whereby a rolling frictional action is exerted by them.
  • the pressure under which said balls are urged against the wall of cylindric casing 7 can be adjusted by suitably controlling the rotor speed.
  • the purpose as required in each case, can be attained by adjusting the hourly throughput of different products and the rotor speed.
  • partition means rotatably-supporting said balls in fixed positions for individual rotation of each ball
  • said partition means defining a spiral path extending along the outer wall of the :rotor
  • said spiral path constituting a passageway for the product passed through the mill whereby the balls upon such rotation by rolling action comminute such material passing through such spiral path.
  • partition means constitute radially extending portions between which the balls are seated, said partition means being defined to provide a guiding portion above and a guiding portion below each ball and a portion between each pair of balls in the same convolution of the spiral path.
