Definitions
- the freeness of the ground material is defined essentially by the shape of the individual ore chunks, in particular by their diameter or by the spectrum of the size distribution.
- the sensors are robust enough to function reliably in the extremely adverse environment, as failure of such a sensor system results in extremely high downtime costs.
- the acoustic fingerprint is intended to be determined according to the invention by means of the electromagnetic drive coils of the mill.
- the mill has a drum in which the material to be ground is during the grinding process and which is driven during the grinding process by a magnetic drive having at least one magnetic segment characterized in that a generated by means of the magnetic drive rotating magnetic field If the drum is set in rotation, a voltage induced in a coil of the magnet segment is determined at least temporarily, and the grinding depth is determined from the determined induced voltage.
- the acoustic spectrum of the drum is first determined from the determined induced voltage and closed from the acoustic spectrum to the degree of grinding.
- the determination of the acoustic spectrum from the freeness is done model-based.
- JESX in a range V n e [a w ; a ], preferably in a range V 0 e [-5%; + 5%], more preferably in a range V c e [-2%; + 2%].
- the determination of the induced voltage and thus the determination of the acoustic spectrum is carried out in particular only when the current flowing to generate the magnetic field in the Magnetseqjroent current I 3 or the voltage applied to generate this current ⁇ B has substantially the value zero ,
- the coil is a coil used to generate the rotating magnetic field. There are thus no additional sensors or other Messwe tauf fashion required, but it can be used on existing components.
- the voltage induced in the coil is one due to a temporal change of the magnetic flux in one
- the temporal change of the air gap is caused by vibrations of the drum, wherein the acoustic frequency spectrum of the vibrations depends on the degree of grinding, in particular in a reproducible manner determined by the freeness, or clearly related to the acoustic spectrum, in particular up to a factor
- the magnetic drive has a plurality of ver around the circumference of the drum ver rushed magnetic segments, wherein for each of the magnet segments individually determined in a coil of the respective magnetic segment voltage is determined and closed from the determined induced stress on the degree of grinding.
- an individual acoustic spectrum can be determined with each of the magnet segments by measuring a voltage induced in a coil of the respective magnet segment and deriving the respective acoustic spectrum from the measured induced voltage.
- the arrangement according to the invention makes it possible to determine the degree of grinding of a material to be ground in a mill.
- the mill has a drum in which the ground material during the
- Milling process is located and during the grinding process by a magnetic drive with at least one magnetic segment driven by that a generated by means of the magnetic drive rotating magnetic field causes the drum in rotation.
- They are a measuring device and a
- the data processing device is designed to conclude from the determined induced stress on the degree of grinding.

- that form
- Magnetic segment and the measuring device one unit.
- the magnetic drive has a plurality of ver around the circumference of the drum ver rushed magnetic segments, wherein for each of the magnet segments individually induced in a coil of the respective magnetic segment voltage is measurable and in the yersein tion of these
- the data processing device is designed to generate an acoustic signal from a measured induced voltage
- the data processing device is furthermore designed to determine, in particular model-based, the freeness from the acoustic spectrum.
- an improved process for He ⁇ averaging the freeness of the ground material is proposed in a mill.
- the mill has a drum in which the ground material is during the grinding process and the organges during the meal by a magnetic drive with at least one magnetic segment is driven by that generated by means of the magnetic drive rotating magnetic field, the drum in rotation.
- the acoustic spectrum of the drum is determined and closed from the acoustic spectrum on the freeness.
- a voltage induced in a coil of the magnetic segment is measured, and the acoustic spectrum is derived from the measured induced voltage.
- the noise spectrum to be evaluated is essentially fed from two sources.
- noises generated by the drive which also include natural vibrations, which are excited in the structure of the mill. These are periodic and thus deterministic.
- This noise component can therefore be quantified and eliminated on the basis of mechanical-acoustic models of the mill, fospw. through a model-based filtering.
- the second source of noise is the millbase to be comminuted by the grinding agent.
- the latter has a shape that results randomly by de breaking process in the quarry or mine.
- the shapes and sizes of the rocks are therefore stochastic. Accordingly, the noises generated by falling off the chunks are also stochastic. There is no temporal correlation of the individual sounds.
- the power source is the engine, whose temporal power is known with sufficient accuracy. But this can also be the suggestions of the mechanical structure of the mill formal darsiser (resonance functions, etc.) and move from the total spectrum ⁇ . Back to the stochastic component which is caused in the Vin ⁇ sentlichen by the trickle of rocks remain.

- the drum 110 mounted at both ends thereof is also rotated.
- a suitable electrical control of the drive or the electromagnetic segments 131 / i the rotational speed of the magnetic field and thus the rotational speed of Troiomel 110 varii rt earth.
- the drum 110 of the ball mill 100 is first, with a grinding means 150, in the case of the ball mill steel balls 150 which is mounted (in the figures, the balls 150 for clarity only partially Be ⁇ reference numbers provided). These have largely identical diameters, at least when new.
- the ore 120 is in the form of fine grains.
- a comparatively high-frequency trickle noise can then be measured.
- the now small ore grains produce a strong damping, so that resonances in the acoustic spectrum around I (ei) no longer or hardly occur. Instead, a continuum of the frequency-dependent acoustic intensity I (o) is to be expected, which has a maximum at higher frequencies (FIG. 2C).
