Definitions

  • a second type of armor plate the mounting of which on the inner surface of the cylindrical shell of the mill is obtained by keying, by means of cylindrical keys, with the two armor plates of the same type which are circumferentially adjacent thereto.
  • the assembly faces of these keyed armor plates are provided with a longitudinal groove, intended to serve as a housing for said cylindrical key.
  • the keyed armor plate of the invention which in known manner comprises at least one assembly face which is provided with a housing intended to receive a key.
  • the key is a ball
  • the housing is designed to receive a portion of the ball.
  • the plates of shielding of a grinder being similar, the part of the ball intended to come into the housing will correspond substantially to a half of ball.
  • the armor plates of the same row 4 were designed to be assembled in pairs by means of cylindrical keys.
  • the shielding plates 5,6 which will now be described are designed so that they can be assembled together by means of spherical keys or balls.
  • the use of balls for the keying of the armor plates of the invention makes it possible to prevent a displacement of these plates parallel to the central axis 2 of the ferrule 1.
  • the initial gap between the armor plates of two rows 4 Adjacent is therefore not modified during grinding, contrary to what can be observed in the case of a coating using cylindrical keys, and for which the gaps between plates of adjacent rows can accumulate over the length of the ferrule, until reaching in certain places 30 mm.
  • the armor plate 5 also has a central opening 7 for the passage of a bolt, in order to make it directly integral with the shell 1.
  • the armor plates 6 differ from the armor plates 5 only in that they do not have a central opening 7, and are therefore not fixed to the shell 1 by means of a bolt.
  • each housing 12 is a frustoconical cavity with an interior wall 12 a and making it possible to receive substantially half a of a ball 13 of diameter d , the other half being intended for be located symmetrically in the corresponding housing of the adjacent shielding plate 6.
  • the ball 13 When the ball 13 is placed in the housing 12, it bears against the interior wall 12 a .
  • the balls 13 had a diameter d of eighteen millimeters, and the initial distance e was equal to one millimeter, which corresponded to an initial gap between plates of two millimeters. It is very easy, thanks to the keyed shielding plate which has just been described, to easily correct the difference between two adjacent plates, by using between the two assembly faces two balls 13 of different diameters, so that that the gap between two assembly faces is constant.
  • the method for making a row 4 by keying the shielding plates 5 and 6 is identical to that known to those skilled in the art for making a row of shielding plates with cylindrical keys, and will therefore not be repeated in the present description.
  • all the shielding plates 5, 6 of a row 4 comprise two assembly faces with each two symmetrical housings which are intended to receive a key in the form of a ball.
  • the assembly of a row 4 will advantageously be completed by the keying of these two particular armor plates, the installation of the last key of a row being easier if it is a key. cylindrical.
  • the covering consists of rows each comprising at least one pair of particular armor plates keyed by means of a cylindrical key
  • said pairs of shielding plates are not aligned in the direction of the central axis 2 of the ferrule 1, but are for example offset radially by a shielding plate in each row, so as to avoid the displacement of these special armor plates, which is inherent in the use of cylindrical keys.
  • the invention is not limited to the particular embodiment which has just been described. It is possible, without departing from the scope of the invention, to design a shielding plate with a single housing, or even more than two housings per assembly face. Other forms of housing can also be designed to receive the balls, in particular in the case of housings of purely conical or even spherical shape.
