Definitions

  • the first and second grinding members form, so to speak, the two terminals of a switch.
  • the grinder is a screen grinder, for example a conical screen grinder.
  • the screen forms the second grinding member, fixed relative to the housing.
  • the raw powder processed by such a grinder 10 typically consists of grains whose average diameter is, for example, between 500 microns and 20 millimeters.
  • the powder, once ground, is formed of grains whose average diameter is between 100 microns and 5 millimeters.
  • Examples of materials that can be ground include active ingredients or excipients for the manufacture of medicines, food products such as lactose, or any other powders for pharmaceutical, chemical or food use.
  • the sieve 30 has a truncated cone shape, with axis Z1. Its perforated wall 32 is inclined at an angle a of, for example, between 20 and 60° relative to this axis Z1.
  • the sieve 30 is arranged inside the casing 20 with its axis Z1 vertical, parallel to - and generally coincident with - the axis Z of the enclosure 24. Its widest end 30a is located upwards, and thus towards a device for supplying the powder to be ground (not shown), which may comprise for example a valve or a metering wheel.
  • the sieve 30 is supported by the support portion 28 of the casing 20.
  • the wall 32 of the sieve 30 is provided with a plurality of openings (not visible in the figure), of any shape, in particular round or square, intended to allow the passage of powder grains of defined maximum diameter.
  • the internal face 32a of the sieve 30 may be smooth or the openings may comprise a beak projecting towards the inside of the sieve, forming a grater.
  • the rotor 40 is arranged coaxially with the screen 30.
  • Each blade 32 is arranged so that one of its edges is permanently flush at a distance d with the internal wall 32a of the screen 32 during rotation.
  • the grinder 10 is provided with a detection system 70 making it possible to detect an undesirable electrical contact between the two grinding members 30, 40, in particular due to the interposition, between them, of an electrically conductive foreign body, for example a metallic body (for example a screw, a bolt, etc.) present in the raw powder.
  • an electrically conductive foreign body for example a metallic body (for example a screw, a bolt, etc.) present in the raw powder.
  • the detection system 70 comprises an electrical control circuit 72 configured to make at least one primary electrical connection between the first and second grinding members 30, 40 and comprising at least one measuring device 90 allowing the measurement of an electrical parameter of the circuit, in particular a multimeter, an ohmmeter, an ammeter or a voltmeter.
  • the two grinding members 30, 40 are electrically separated from each other by electrically insulating elements, so that the primary electrical connection(s) constitute the only passages for an electric current between the two members, during normal operation of the grinder.
  • At least one first intermediate piece 50 is interposed laterally between the external wall 22 of the casing 20 and the upper end 30a of the sieve 30.
  • This intermediate piece 50 has an electrical insulation function, but it can also allow the sieve 30 to be fixed relative to the casing 20, and/or ensure sealing between the sieve 30 and the casing 20. The raw powder to be ground is thus prevented from passing directly into the downstream part 14 of the mill 10 without having passed through the sieve 30.
  • the first intermediate piece 50 is arranged to border the upper end 30a of the sieve 30 over its entire periphery and thus forms a closed contour. It may for example be an annular-shaped piece.
  • the first intermediate piece 50 may for example be fixed to the sieve 30 and to the casing 20 by gluing.
  • the crusher 10 could comprise a plurality of first intermediate parts 50 at the periphery of the screen 30, making it possible to isolate the screen 30 from the external wall 22 of the casing 20.
  • other means can be implemented to ensure the necessary sealing.
  • the screen 30 is also isolated from the support portion 28 of the casing 20, at its lower end 30b, by at least one second intermediate piece 52 made of non-conductive material.
  • the second intermediate piece 52 is arranged on the upper face of the support portion 28, and the lower end 30b of the screen 30 rests and is advantageously fixed, for example by gluing, on said second intermediate piece 52.
  • the insulation can also be provided by a non-conductive coating.
  • a non-conductive coating would be applied in particular to the screen 30 and/or to the parts of the casing holding this part (here in particular the support portion 28 and/or the external wall 22 of the casing 20).
  • the rotor 40 is mounted directly on the support portion 28, and therefore in electrical contact with this portion 28 and the entire casing 20.
  • the electrical control circuit 72 comprises a first branch 74 connected to a first contact point B1 of the sieve 30 on the one hand and to a contact point A1 of the casing 20 on the other hand.
  • the first branch 74 includes a resistive element 80 or grounding resistor, of resistance R, by means of which the sieve 30 is connected to ground.
  • the resistance R is preferably between 1 ohm and 1 megaohm to allow a sufficiently rapid and effective electrical discharge if necessary.
  • connection point A1 to the casing 20 is, due to the electrical contact between the rotor 40 and the casing 20, also electrically connected to the rotor 40.
  • FIG. 1 illustrates the gap 60 of width d separates the rotor 40 and the screen 30, so that an electric current cannot pass directly from one to the other through said gap.
  • the gap 60 is thus equivalent to an open switch or to an infinite resistance R AB .
  • figure 2 illustrates the electrical diagram equivalent to the assembly of the figure 1 , in normal operation.
  • the resistance R2 is infinite, and the equivalent resistance R eq is substantially equal to R1 and therefore to the resistance R of the resistive element 80 (Equivalent diagram of the figure 2 ).
  • the measuring device 90 detects an infinite resistance Req. (Equivalent diagram of the figure 4 )
  • the measurement results are transmitted to the processing device 92 configured to detect, from the measured equivalent resistance value, the presence of an additional electrical contact between the grinding members 30, 40.
  • the processing device 92 communicates with the automaton (not shown) which controls the grinder 10, so that an alarm and/or a total shutdown of the grinder 10 can be triggered in the event of an abnormal measurement.
  • FIG. 5 illustrates a grinder according to an example not included in the invention. Contrary to what has been described previously in connection with there figure 1 , the measuring device 90 is here mounted directly at the terminals of the resistive element 80. The resistive element 80 and the measuring device 90 are therefore connected to the same contact point B1 of the sieve 30.
