Definitions

  • the present invention relates to a method for adjusting the operation of a material grinding apparatus, in which the noise emitted by the apparatus, the power absorbed by it, and the feed rates of the material are recorded. apparatus and outgoing crushed material. It also extends to a device for implementing this method.
  • French patent FR-A-2140782 of the Applicant relates to an adjustment device of this kind, comprising one or more sensor members of one or more variables related to the charge rate, in particular of the noise generated by the device, and means for maintaining the charge flow at a predetermined value according to the indications of the sensor member.
  • the adjustment of the charge flow rate does not necessarily provide the best operating conditions when the properties of the material to be ground (grain size, friability, humidity, etc.) are variable. In this case, there is a risk of not obtaining the optimum yield and a constant quality of the ground material, which may be insufficient at times or, on the contrary, excessively.
  • the object of the present invention is to remedy these drawbacks, and to provide a method and a device for adjusting the operation of a grinding apparatus which is not very sensitive to changes in the properties of the material to be ground, and constantly ensures a yield of 1 grinding operation close to the optimum value.
  • the method according to the invention is characterized in that the flow of material admitted into the apparatus is adjusted as a function of the variables recorded so as to maintain the quantity of material present in the latter at a constant high value, close to that for which the efficiency of the mill is maximum.
  • a rapid coarse adjustment of the quantity of material in the grinder is ensured as a function of the flow rates of incoming and outgoing material, and a slower fine adjustment as a function of the noise emitted and the power consumed by the device.
  • the device according to the invention comprising a sensor of the noise emitted by the grinding apparatus, a sensor of the power absorbed by it, a sensor of the flow of material introduced into the apparatus, a sensor of the flow of crushed material outgoing, and a device for adjusting the flow of material introduced into the device, is characterized in that it further comprises a computer weighting the indications of the sensors into a global signal of the amount of material in the device, a regulator giving a correction signal as a function of the global signal of the computer and of a setpoint signal, and a comparator giving to said device for adjusting the material flow rate introduces a correction order as a function of the correction signal of the regulator and the flow rates of material entering and leaving the device.
  • the ball mill 1 with a rotating closed tank, of horizontal axis, is supplied with coal to be ground by the conveyor belt 2, the motor rollers of which are driven by the electric motor 3, the speed of which is recorded by the tachometer 4.
  • the crusher is rotated by the electric motor 5, by means of a pinion engaged on the ring gear 6.
  • the power absorbed by the motor 5 is recorded by the wattmeter 7.
  • a diaphragm 9 allows the measurement of the entrainment air flow, representative of the evacuation of charcoal flow, by means of the flow meter 10.
  • a member 11 for recording the noise level generated by the grinder is connected to the computer 12 by the link 11A.
  • the latter also receives via the link 4A the indication of the tachometer 4 of the drive motor of the conveyor belt supplying the coal to be ground, by the link 7A that of the power absorbed, measured by the wattmeter 7, and by the connection 10A that of the flowmeter 10 indicative of the flow rate of ground coal evacuated. It weights these different indications and draws a correction signal from them, which it transmits on the one hand by circuit 13 to regulator 14, on the other hand by circuit 15 to display devices of the power consumed and the quantity of coal present in the mill.
  • the regulator 14 compares the indication of the quantity of coal in the mill transmitted by the computer 12 with a reference value, and draws a signal therefrom. correction, which it transmits to the comparator 16.
  • the latter also receives by the circuit 17 the indication of the tachometer 4, representative of the feed rate of material to be ground, and by the circuit 18 the indication of the flow meter 10 , representative of the flow rate of ground material discharged. It draws from it a signal for correction of the feed rate of the coal mill, this signal generating a rapid, but approximate correction, if it comes from the comparison of the feed and discharge rates, and a slower correction, but more precise, if it comes from the comparator 14.
  • the correction signal is transmitted by the circuit 19 to the motor 3 for driving the conveyor belt supplying the mill.
