Definitions
- the present invention relates to a vibrating mill, preferably a disc vibrating mill, comprising a grinding unit and a Schwingan- drive, by means of which the grinding unit can be excited to the drive speed of the oscillating drive dependent vibrations.
- Such vibratory mills are used in particular for grinding a sample of free-flowing, granular ground material in the course of preparing the sample for desired analyzes, for example for X-ray-based investigations of the elements contained with suitable equipment (eg XRF). Also regrind, which is rinsed by a liquid in the grinding chamber, is conceivable.
- the sample which may be, for example, a rock sample, ore, slag, etc., is mixed and ground in the vibratory mill with auxiliaries and then pressed with auxiliary pressing additives into a tablet which is fed to an analyzer for analyzing the constituents becomes.
- the sample must be crushed in such a way that all components give a homogeneous mixture, for which a fine and uniform comminution of the material to be ground in the vibratory mill is essential. Often it is required that after the milling process a certain proportion of the particles (for example 90%) must fall below a certain size (for example 32 ⁇ m). For a quantitative determination of ingredients it is also essential that the analysis is based on a well-defined sample size.
- a controlled automatic vibratory mill can have a metering device for feeding the milling unit with regrind and auxiliaries in always exactly defined quantity. At the end of an adjustable grinding time (so-called grinding phase), the ground sample material is emptied into a sample collecting container during an adjustable discharge phase.
- compositions of the material to be ground it may, in particular after the end of the grinding cycle in the automatic discharge to adhesions in the milling unit, in particular in the Austrags Schemeen the Grinding vessel, the discharge area and the spout come.
- the discharge area and the spout come.
- the adherences contaminate a subsequent sample and make it unusable for analysis.
- attempts have been made to improve the uniqueness and reproducibility of the samples to be analyzed by cleaning all affected components in the machine after each grinding process in a customary manner so that contamination of a sample with waste material is reduced to a level permissible for the analysis becomes.
- this cleaning requires a perceived as disadvantageous labor, time and thereby cost.
- the object of the invention is to further develop a vibrating mill of the type mentioned above in terms of use, so that in particular the abovementioned disadvantages are reduced.
- the object is achieved according to the invention first and essentially in conjunction with the features that the vibrating mill speed change means suitable for pre-definable and insofar during operation independent, time-dependent change in the resulting or effective drive speed during operation of the vibratory mill or on - are fitted.
- This is based on the found finding that attachments of regrind, which can form at a low for the grinding itself drive speed or vibration frequency of the milling unit, by one or more brief changes in the grinding unit acting on the drive speed or frequency of the walls of Remove the vibrating mill, so that the expense for subsequent cleaning is eliminated or at least reduced.
- the quality of the sample is reproducibly increased.
- the drive speed or oscillation frequency of the grinding unit which is itself favorable for the grinding process, is determined on the one hand by the Sample material, in particular by its density, co-determined.
- suitable for the grinding operation drive speed also depends on the design of the vibratory mill. While designs in which the material to be ground is crushed between the ball-shaped grinding bodies filled into a grinding container, for example, have a comparatively high frequency, so-called plate-type vibrating mills, in which a milling space surrounded by a cylindrical grinding wall has a smaller diameter Mahlring and / or a therein contained, again reduced diameter circular grinding stone swing, operated due to the damage-sensitive structure at a relatively low frequency.
- the invention preferably relates to such disk vibrating mills, but may also find application in other types, such as. Bechermahlmühlen find.
- the oscillating drive has a drive motor, preferably an electric motor, and at least one of them driven, preferably navangetrie- bene, imbalance.
- the speed change means comprise a control device and / or a control device for controlling adjusting means for changing a drive rotational speed initially predetermined by the drive motor and / or for direct driving of the drive motor itself. If the speed change means act on said adjusting means, then a drive speed predetermined by the drive motor without such action can be changed, preferably reduced.
- the drive motor for changing the drive speed or oscillation frequency can be directly controlled by the speed change means.
- the oscillating drive by means of the speed change means, preferably by means of electrical and / or electronic circuits contained therein and / or electrical and / or electronic storage means and / or computer or program-based, for specifying at least a predetermined effective drive speed-time Course is suitable.
- a particularly high effectiveness for the removal of adhesions is achieved when the drive speed-time course starting from a predetermined basic speed includes a one or more times increase to a maximum speed which is greater than or equal to a resonance speed at which the grinding unit excited to resonant vibrations becomes.
- Preferred is a design of the vibrating mill, in which structurally conditioned the vibrations of the grinding unit and their discharge area (eg., An annular, located below the grinding floor discharge channel) and detect the outlet.
- said change in the input rotational speed or oscillation frequency preferably acts on these regions to obtain a transient resonance, permanent adhesion of ground sample material is prevented and a uniform, reproducibly complete discharge of the sample is made possible. It was found that the very short-term passage through the resonance frequency or resonance oscillation is extremely effective for detaching adhesions. In order to avoid damage, in particular to disk vibrating mills, it is therefore preferred that the selected maximum speed, up to which the drive speed is increased, is greater than the speed causing the resonance (so-called resonance speed). It is possible that the drive speed-time course has a holding phase of this maximum speed or that the speed is lowered immediately after reaching the maximum speed again.
- the drive speed-time curve after a rise to the maximum speed, a return to the base speed and subsequent thereto loom preferably has a new holding phase of the base speed. It is considered appropriate that the drive speed-time curve cyclically has a multiple increase from the basic speed to the maximum speed. The repeated repetition further improves the detachment of adhesions. It is also preferred that, according to the resulting drive speed-time course of a grinding phase and a discharge phase depending on a basic speed (either the same or different) is assigned and that in the milling phase and / or in the discharge phase in each case at least an increase in the input speed of the basic speed is included in a maximum speed.
- the speed change means comprise electrical, mechanical, electromechanical, pneumatic, hydraulic and / or magnetic, preferably electromagnetic, speed change control means.
- an electric adjusting means comes, for example, in a AC drive motor, a frequency converter, in a Gleichström drive motor, a power converter into consideration.
- a mechanical adjusting means for example, a mechanical brake is suitable, which acts on a driven by the drive motor shaft or components mounted thereon.
- a pneumatic actuator is, for example, a pneumatic brake into consideration.
- a hydraulic brake, an eddy current brake, an electromagnetically acting brake, etc. use.
- the speed change means change the drive speed by means of electrical, mechanical, electromechanical, pneumatic, hydraulic and magnetic, preferably electromagnetic damping.
- a high, in particular the said maximum speed corresponding drive speed of the drive motor can be lowered by the speed caused by the speed change means damping during the grinding and / or Austrags termes the vibratory mill initially to said basic speed.
- the controller may cause the damping to be canceled at a desired time or decreased in a controlled manner, thereby reducing the damping resulting drive speed increases up to the maximum speed.
- the adjusting means are in turn suitable for increasing the drive speed, for example. It may be an electric, pneumatic or similar motor.
- the speed change means automatically change the resulting drive speed and thus also the vibration of the grinding unit in the predetermined course after appropriate adjustment in operation at the desired time linearly and / or nonlinearly.
- the speed change means are designed as a module of the vibratory mill.
- the speed change means the module, may provide for cyclically varying the drive speeds of the drive unit during the milling operation and / or during the discharge phase of the sample from the milling unit.
- the vibrating mill has a cooling device acting in particular on the grinding wall surrounding the grinding space.
- cooling grooves for the flow of a coolant such as water
- a coolant such as water
- the invention also relates to a method for operating a vibrating mill, preferably a disc vibrating mill, which has a grinding unit and a vibrating drive, wherein the grinding unit is excited by the oscillating drive to oscillations dependent on their driving speed.
- the invention has the object, advantageously further develop such a method, so that in particular adhesions of material to be ground in the vibrating mill avoided or at least reduced.
- the drive speed is changed in a predetermined manner during operation of the vibrating mill.
- the drive speed according to a predetermined drive speed-time course preferably automated, is changed.
- the effective or resulting input speed is increased from a basic speed one or more times up to a selected maximum speed which is greater than or approximately equal to a resonance speed at which the grinding unit is excited to resonance vibrations.
- the drive speed for a desired defined time interval can be maintained at the maximum speed.
- the drive speed can be lowered again to the base speed after an increase to the maximum speed and preferably maintained at the base speed for a further time interval.
- the resulting drive speed can be cyclically increased several times from the basic speed to the maximum speed and lowered again to the basic speed.
- a distinction can be made automatically between a grinding phase in which the millbase is comminuted and a discharge phase in which the millbase is discharged from the vibrating mill.
- the effective drive speed of an associated basic speed which differ between the grinding and discharge phase or the same each chen value is increased to a maximum speed that is greater than or equal to the resonance speed.
- the drive speed can be carried out appropriately by means of an electrical, mechanical, electro-mechanical, pneumatic, hydraulic and / or magnetic, preferably electromagnetic damping, but alternatively also by an active increase of a predetermined by a drive motor drive speed by means of an auxiliary drive. It is possible to change the drive speed and thus also the oscillation frequency of the milling unit linearly and / or nonlinearly.
- the grinding unit preferably the grinding wall which surrounds the grinding space, can be cooled.

- the outer diameter of the Mahlringes 6 is smaller than the inner diameter of the grinding wall 4, and the outer diameter of the grinding stone 7 is smaller than the inner diameter of the Mahlringes 6.
- Mahlspalt 8 and the Mahlspalt formed between Mahlring 6 and Mahlstein 7 9 allow a lateral relative movement of Mahlring 6 and millstone 7 both to each other and with respect to the grinding wall 4.
- Mahldeckel 10 is sealed on the top side.
- the vertical distance between the grinding base 5 and the grinding cover 10 is only slightly greater than the height of the grinding ring 6 and the grinding stone 7, so that just the desired Game for the lateral movement arises.

- the cylinder 21 has two ports 23, 24 for supplying a pressurized fluid, such as air or a hydraulic fluid.
- FIG. 1 also shows that the grinding unit 2 is equipped with a cooling device for the rear or external cooling of the grinding wall 4.
- this comprises two cooling grooves 47 adjoining the grinding wall 4 at the back, which are introduced into the inner wall surface 48 of the housing ring 11, which supports the grinding wall 4 on the outside.
- the upper and lower cooling grooves 47 which extend in the circumferential direction from a coolant inlet 49 to a circumferentially spaced by about 10 °, not shown in the drawing flow for the coolant, are spaced by a likewise ring-segment-like support projection 50 which in Area of inlet and outlet is interrupted.
- the inlet and outlet are separated by flow in the circumferential direction, so that a targeted circulation of coolant, which can be regulated, for example, to a desired temperature, is possible.
- Figure 2 comparatively shows a second operating position in which the upper port 23 is acted upon by a pressurized fluid.
- a pressure application surface of the piston 22 is acted upon from above in a manner not shown, so that the piston 22 pulls the grinding base 5 down until it enters into a defined positive stop with a collar 27 of the housing base 12 ,

- this has a drive motor 35, here an electric motor, on whose shaft 36 rotates in an overlying housing 37 to the shaft 36 off-center, known per se and therefore illustrated simplified unbalance 40.
- the torsional vibration generated in this way is transmitted via the drive flange 13 to the connected entire milling unit 2, including all walls involved in the grinding process and in the discharge process of the grinding stock.
- FIG. 3 shows schematically a control device 38, which is a component of speed change means 39 according to the invention.
- the motor 35 is fed by a device not shown with an operating voltage, which is initially associated with a specific drive speed of the shaft.
- the control device 38 is suitable for driving with adjusting means 41 arranged in the housing 37 in a predetermined, temporally variable manner.
- the adjusting means 41 are a brake which acts on the eccentric unbalance 40 from two opposite sides and which is indicated schematically.
- a desired characteristic can be preselected on the control 38 by means of a control panel 42, which either determines the time profile of the actuation of the actuating means 41 or a characteristic curve which immediately corresponds to a desired resulting course of the resulting drive rotational speed over time.
- the control signals are transmitted via a line 43 to the adjusting means 41 and translated in the example in a suitable form in a corresponding, time-varying compressive force with which the brake piston delaying the unbalance 40 occur.

- the controller 38 may also communicate with the motor 35 directly, for example.
- a speed signal is fed.
- the controller 38 is adapted to the operator display on a display 45 directly from the selected settings resulting on the milling unit acting Antriebsnaviere- time course 46, wherein the drive speed U via the time t is applied. From FIG. 3, it becomes clear in conjunction with FIGS. 1, 2 that the plane of rotation of the imbalance 40 is perpendicular to the vertical surfaces of the grinding wall 4, grinding ring 6 and grinding stone 7, which cause the grinding process, and at right angles to the lateral boundaries of the discharge channel 29 is arranged. This has an advantageous effect on the separation of the adhesions when passing through the resonance frequency.
- FIGS. 4a-4c show various examples of preferred drive speed-time curves 46.
- the oscillating drive is switched on at the time t.sub.i, ie the operation begins.
- the drive speed Umax resulting from the motor voltage is lowered right at the beginning according to the activated actuating means 41 (brake) to a desired base rpm U rated, which is desired for the grinding operation.
- the effect of the actuating means 41 is linearly reduced starting from the time t 2 to t3 by means of the controller 38 until the effective drive speed U corresponds to the maximum speed Umax.
- a speed value URes is passed through, in which the grinding unit 2 is excited to resonance vibrations.
- the control device 38 controls the effect the adjusting means 41 (brake) increased linearly until at t4 the basic or rated speed Unenn again results.
- the resonance speed UR passes through it in a controlled manner.
- the basic rotational speed Unenn is maintained for a further time interval t4-ts, and the grinding process is ended at ts.
- the basic speed Unenn is, for example, about 800 to 850 revolutions per minute (rpm)
- the resonance speed is, for example, in the range of 1000-1100 rpm
- the maximum speed Umax reached is for example, 1300 rpm.
- the resonance speed UR it after the grinding process at the time t 2 was already performed predominantly, twice in a controlled manner, namely, once upward and once downward by drive at a preselected slope of the curve path. Since neither Unenn, nor Umax resonance occurs in the milling unit and UR it is not kept constant while driving through, the milling unit 2 is only defined for a short time in resonance, so there is no risk of damage. Alternatively, it would be conceivable to keep the resonance speed constant for very short time intervals in which no damage can also occur.
- FIG. 4b shows a second exemplary embodiment in which the resonance speed is likewise traversed linearly in the case of a total trapezoidal resulting drive speed / time profile 46.
- a total of two throughput cycles uniformly distributed therein are provided during the grinding time ti ts.
- Figure 4c shows a third preferred embodiment. The resonance speed is traversed here in three cycles with a rounded course, similar to harmonic areas with interruptions.
