Definitions

  • This invention relates to a continuous mill of horizontal drum type, a typical but non-exclusive use of which is in the ceramics sector for crushing material used in tile manufacture.
  • mills comprising a large cylindrical drum of horizontal axis which is rotated about itself and comprises two opposing coaxial ports for loading the material to be crushed and for discharging the crushed material respectively.
  • a problem connected with such mills, and for which an adequate solution has not been found, is to provide a support system able to adequately withstand the weight of said large drum and the material contained in it.
  • said support is provided by two projecting hollow cylindrical hubs coaxially positioned on the front and rear ends of the drum, and through which the material entering and leaving passes respectively.
  • the drum is supported by two opposing pairs of contact rollers with axes parallel to each other and to the drum axis, they being coated with rubber or another elastomer of good friction coefficient, and are driven to rotate the drum.
  • the mill has therefore to be halted fairly frequently to replace the rollers, with consequent renovation costs and loss of production.
  • the main object of this invention is to obviate the aforesaid within the context of a simple and rational construction.
  • the drum of horizontal axis is positioned on two opposing pairs of idle contact rollers of hard material having their axes parallel to the drum axis, the drum being rotated by at least one belt transmission.
  • Said idle rollers are preferably constructed of steel, and more preferably of surface-treated or special steel, with these there corresponding respective metal rolling tracks on the drum.
  • said belt transmission preferably comprises two separate drive units, each of which comprises a plurality of V-belts.
  • said drive units are associated with respective drum parts outside the central drum portion lying between said pairs of idle steel rollers.
  • the advantage deriving from said arrangement is that the tension of the belts of said units provides a bending moment which balances most of the bending moment due to the weight of said central drum portion, with consequent excellent bearing of said idle rollers against the respective rolling tracks.
  • Suitable means are also provided for adjusting the belt tension.
  • Figure 1 is an external side elevation of the invention
  • Figure 2 is a view to an enlarged scale in the direction II of Figure 1.
  • each pair of coaxial supports 3 there is rotatably mounted a steel roller 4 against which there rests a respective metal annular rolling track 5 associated with the horizontal drum 6 of the continuous mill 7.
  • Said rollers 4 and said tracks 5 are either surface-treated or constructed of special steel.
  • the two tracks 5 are spaced from the end transverse walls of the drum by the same distance, said walls each comprising a central aperture 8 (of which only one is visible in Figure 2).
  • each part of the drum 6 situated external to said tracks 5 there is provided a series of identical equidistant circumferential grooves 9 of V cross-section, with which a corresponding number of V-belts 11 engage and pass about an underlying grooved horizontal drive roller 12.
  • the drive roller 12 is driven by a geared motor unit 13 with incorporated step-down gear, said drive roller 12 and unit 13 being positioned on a flat frame 14 hinged at 15 to a support base 16.
