Definitions

  • the present invention relates to a rotary mill comprising a cylindrical shell fitted with an inner shielding and intended for contain material to be ground and a load of grinding media, in which the shielding, which consists of rings of shielding plates individual juxtaposed, has longitudinal undulations interior to favor the lifting of the load and the material to grind during rotation of the grinder.
  • the invention relates more particularly to the shredders used in cement plant and in the mining industry.
  • These shredders are made up of a metallic cylindrical ferrule rotating around its axis longitudinal and containing a grinding load made up of machines grinders, usually balls, but can also be made up of cylpeps, boulpeps, etc. of variable dimensions.
  • the material to be ground is introduced on one side of the mill and, as and when measure of its progress towards the exit, on the opposite side, it is crushed and crushed between the crushing machines.
  • the shielding must have a profile such that it picks up the load up to a level such that it remains compact because a lift too important causes the projection of balls beyond the foot of the charge, that is, the balls directly hit the shield, without interposition of material to be ground.
  • the load must be raised enough so that there is good mixing of the mass. It goes without saying that the filling coefficient plays a role determining in the grinding efficiency and that the shaped area bean occupied by the load must have a shape, a position and well-defined dimensions for efficient grinding and optimal.
  • the armor plates are subject to wear intense so that even if the lifting conditions are optimal at the start, they can deteriorate quickly due to change of the profile of the plates caused by wear.
  • Document DE 1126709 describes a crusher whose plates of shield form steps in the direction of rotation. different plates of different radial depths follow one another in a determined order. The side with the greatest radial depth is found at the front, seen in the direction of rotation. This presents the disadvantage that the grinding machines are projected, which reduces grinding efficiency and increases the risk of plate rupture.
  • the steps of a ring are offset from the terraces of an adjacent ring, i.e. the terraces are not axially aligned. This causes shear forces which increase the speed of wear of the plates on the edges.
  • Document WO 86/04267 also describes a grinder, the armor plates are arranged in steps to form lifting ramps. In this grinder, there is, in fact, only one type bleachers. In addition, the plates are bolted to the ferrule of so that the arrangement of the plates is limited to the configuration of the holes in the shell.
  • the object of the present invention is to provide a new type shielding which alleviates the disadvantages described above and, more particularly, a grinder whose shield is formed of armor plates which allow the lifting profile to be adapted to parameters and operating conditions of the mill and which changes less quickly due to wear.
  • each plate has, on the rear face, seen in the direction of rotation, a step with a higher radial height than the front face, in this that each plate ring has several types of plates which differ, at least, by the radial height of their tier and by the nature of their material and which follow one another in the circumferential direction, according to a determined order.
  • a certain number of one of the types of plates are bolted mounting plates at the ferrule, all the other plates not necessarily fixed to the ferrule by bolts but being held in place by simple arch effect.
  • the different types of plates also differ in the nature of their material. We can therefore combine different types of plates depending on their risk of wear. It thus becomes possible to produce a profile of lift which is less vulnerable to wear, i.e. to keep longer the initial lift profile. It is also possible to combine the plates optimally to have both good wear resistance and good impact resistance.
  • Armor plates with the exception of fixing plates, preferably have, on their radial faces, at least one longitudinal rib, respectively a longitudinal groove corresponding or vice versa to interlock with each other and be held in place by the fixing plates.
  • Each of the plates is preferably sized to so as not to exceed a weight of 25 kg. This reduced weight facilitates handling of the plates and is within the limits imposed by new legislation.
  • smaller, chunky plates allow the use of less resilient steels or cast iron, which allows to choose better compromises wear / impact resistance than with conventional shields.
  • FIGS 1 and 2 show different types of plates shield 10, 10a, 12 and 14 having a slightly outer surface curve to match the inside of the cylindrical shell of the grinder indicated schematically by the reference 16. Seen in the direction of rotation of the mill, represented by arrow A, every plates have a front face whose height is less than that of the rear face so as to define a step on the side rear of each plate, step which has a rounded 10b, 12b, 14b, so that the juxtaposition of the plates creates a wavy profile.
  • the different types of plates are distinguished at least by the height of their rear face, that is to say the height of their step 10b, 12b and 14b. This is how the step 14b of the plates 14 is more marked as the step 12b of the plates 12 which, in turn, is more marked as the step 10b of the plates 10 or 10a. From the point of view of contribution to the shape of the interior profile, plates 10 and 10a are identical since they have the same tier. The plaques 10 and 10a can therefore be considered of the same type, so that Figures 1 and 2 show three different types of plates.
  • plates 10a are fixing plates and have, for this purpose, an opening central 18 to be bolted to the shell 16 through a hole of the ferrule 16.
  • each plate has, on the rear face, over the entire length, a groove 20 and on the front face, a corresponding rib 22 which can be engaged in the groove 20 of the previous plate.
  • the grooves 20 and the ribs 22 can, of course, be reversed.
  • the fixing plates 10a have neither rib nor groove.
  • the front and rear faces are smooth and re-entrant, converging thus towards the ferrule 16.
  • the timing is achieved by means of corners 24 and 26 of triangular section which are inserted between the plates of fixing and neighboring plates. These corners 24 and 26 have inclined inner faces complementary to the inclined faces of the mounting plate 10a.
  • the outer faces of the corners 24 and 26 are straight and provided with a groove 20, respectively with a rib 22 to fit into the rib 22, respectively in the groove 20 of the adjacent plates.
  • the different types of plates 10, 12 and 14 can be differentiate, in addition to the height of their step, by the nature of their material or alloy.
  • the plates most exposed to wear in particular the plates 12 and 14 with the most marked step, can be made of cast iron with good wear resistance and plates 10 which are less exposed may be made of steel. We see thus to a more regular wear which maintains the profile longer initial reliever.
  • the overall dimensions of the different plates are preferably such that their weight does not exceed 25 kg.
  • their outer side ferrule side has indentations as shown schematically in lines interrupted 28.
  • Figures 3 and 4 show a first example of arrangement plates according to which only two types of plates are used 10 and 12 and according to which, on each plate of a type 10 or 12, are juxtaposed two plates of the other type 12 or 10.
  • FIGs 5 and 6 illustrate an arrangement similar to previous but here, we alternate the type 10 plates with those of type 14.
  • Figures 7 and 8 illustrate an example of arrangement with a double alternation of the three types of plates 10, 12 and 14.
  • the chosen combination is: 10-12-10-14-10-12 ..., that is to say that there is twice as many type 10 plates as type 12 plates and type 14 plates.
  • the conditions are different depending on which one is on the side of entrance or exit side, especially as a result of grinding progressive and changing grain size of the material to be ground.
  • the invention therefore provides for a new crusher with shielding perfectly modular and adaptable to conditions and parameters variables.
