Description
Technical field
The present invention relates to a kind of vibromill, preferred discotic vibromill, this vibromill has grinding unit and vibratory driver, and grinding unit can produce the vibration relevant with the driving rotating speed of vibratory driver by means of this vibratory driver excitation.
Background technology
Such vibromill is particularly useful for the sample process of the analysis---for example by suitable equipment element that inspection comprised (for example XRF) based on X ray---that is used for wishing in preparation, and vibratile, granular abrasive material is pulverized into sample.Also can consider to spray into the abrasive material of grinding chamber by liquid.For example can be that the sample of rock, ore, slag or the like mixes with auxiliary material in vibromill and grinds, provide equipment to be compressed into tablet by aux. pressure then, be to analyze composition, and this tablet is transported to analytical equipment.Sample must pulverize all uniform ingredients are mixed, and therefore, abrasive material is meticulous and to pulverize equably be important in vibromill.Usually requirement, a certain proportion of particle behind process of lapping (for example 90%) must be lower than certain size (for example 32 μ m).In addition, what respectively comprise material quantitatively is important, will be based on exactly determined sample size because analyze.For this reason, in check automatic vibromill can have proportioning device from exactly determined amount to grinding unit that carry abrasive material and auxiliary material with.After the grinding duration that can set (so-called grinding stage) finished, the sample material that has ground was discharged in the sample receiving vessel at the output stage that can set.Some compositions of abrasive material especially finish the back at process of lapping and can stick in the grinding unit when exporting automatically, especially are bonded in the output area of grinding container, output area and outlet.This causes, and not every sample size can both be used for analyzing, and therefore analysis result is made mistakes.There is such danger in addition, can pollutes ensuing sample, and make it be not useable for analyzing owing to adhere to.Attempt improving thus the uniqueness and the reproducibility of sample to be analyzed up to now, promptly, after each process of lapping,, make sample be reduced to for analyzing reliable degree by the pollution of material before with all the relevant parts in the common mode cleaning machine.But this cleaning requires tangible work, time and cost consumption unfriendly.
Summary of the invention
In view of this, technical problem to be solved by this invention is to help making land used to further develop the vibromill that this paper starts described type, makes aforesaid drawbacks especially reduce.
According to the present invention, this technical problem at first and mainly solves in conjunction with following feature, promptly, vibromill has the rotating speed modifier, this rotating speed modifier be applicable to or be matched with can predesignate and therefore in running automatically, change according to the time and to produce or effectively to drive rotating speed in the vibromill running.This is based on such cognition, promptly, the bonding of the abrasive material that forms under driver rotating speed favourable, grinding unit or vibration frequency for process of lapping itself can change the driver rotating speed that acts on the grinding unit or frequency in short time by one or many and come off from the wall of vibromill, makes ensuing cleaning expend and is removed or is reduced at least.The quality of sample can improve with reappearing.Grinding unit for the favourable driving rotating speed of process of lapping itself or vibration frequency on the one hand by sample material, especially together determine by its density.On the other hand, it is also relevant with the structure of vibromill to be suitable for grinding the driving rotating speed of operation.Wherein, though abrasive material in the grinding container of packing into, for example pulverized structure can be born high relatively frequency between the spherical abrasive body, but so-called plate-like vibromill moves under low relatively frequency damaging sensitivity owing to structure, wherein, by the littler grinding ring of a diameter of the grinding chamber inside of columned mill wall limited boundary and/or the grinding stone that is arranged in circle grinding ring, that diameter further reduces in vibration.The present invention preferably relates to such plate-like vibromill, but also can use other version, grinds as cup-shaped.Preferably, vibratory driver has CD-ROM drive motor, preferably motor and at least one out-of-balance mass by rotation driving its driving, preferred.Be considered to advantageously, the rotating speed modifier has control device and/or adjusting device, is used to control to adjust device and changes at first by the driving rotating speed of CD-ROM drive motor output and/or be used for directly controlling motor itself.If the rotating speed modifier acts on the described adjusting device, can make CD-ROM drive motor not have driving rotating speed given in advance under this effect to change, preferably reduce by described adjusting device so.As an alternative, CD-ROM drive motor for a change drives rotating speed or vibration frequency and is directly controlled by the rotating speed modifier.There is such possibility in both cases, in automatic vibromill, preferred discotic vibromill, driver at first makes grinding unit carry out in the specific vibration according to the driving rotating speed of introducing that is produced, and this vibration is coordinated with each component of abrasive material according to control or adjusting mutually for process of lapping or grinding stage.Set out by this basic rotating speed or rated speed, can preferably finish, also can in process of lapping, change rotating speed (the preferred increase), with the peel adhesion thing by means of the rotating speed modifier at process of lapping.There is such possibility, vibratory driver is by means of the rotating speed modifier, preferably, be applicable at least one predetermined effective driving rotating speed-time graph given in advance by means of storage device and/or the computer or the program support of the circuit that is included in the electric and/or electronics in the rotating speed modifier and/or electric and/or electronics.If drive rotating speed-time graph from predetermined basic rotating speed, comprise that one or many rises to maximum (top) speed, this rotating speed greater than or approximate resonance speed (under this rotating speed grinding unit be energized produce resonance), peel adhesion thing so especially expeditiously.Preferably have a kind of like this structure type of vibromill, wherein certain vibration that detects grinding unit and output area thereof (for example annular, be positioned at the output channel of grinding below the bottom) and outlet place on the structure.If the change of described driving rotating speed or vibration frequency preferably realize act on these zones under the situation of resonance of process, the sample material that prevents to have ground is continued to adhere to, and realizes that sample evenly, reproducible exports fully.In this discovery, be the peel adhesion thing, be especially effective through resonant frequency or resonance very in short time.In order especially in the plate-like vibromill, to avoid damage, it is therefore preferable that the driving maximum (top) speed that rotating speed was elevated to always is greater than the rotating speed that causes resonance (so-called resonance speed).Have such possibility, drive the resident stage that rotating speed-time graph has this maximum (top) speed, or rotating speed descends after reaching maximum (top) speed at once once more.Preferably, drive rotating speed-time graph and after rising to maximum (top) speed, return to basic rotating speed, and then preferably have the new resident stage of basic rotating speed.Driving rotating speed-time graph periodically has repeatedly, and the rising from basic rotating speed to maximum (top) speed is considered to favourable.By repeatedly repeating further to improve peeling off of bur.In addition preferably, each correspondence of driving rotating speed-time graph that is produced according to grinding stage and output stage sets a basic rotating speed (or identical or different), and comprises at least one rising from basic rotating speed to maximum (top) speed that drives rotating speed respectively in grinding stage and/or output stage.Have such possibility, that the rotating speed modifier has is electric, the adjusting device that is used to change rotating speed of machinery, electromechanical, pneumatic, hydraulic pressure and/or magnetic, preferred electromagnetism.As electric adjuster spare, for example can under the situation of AC driven motor, consider frequency converter, under the situation of direct-drive motor, consider rectifier.As the adjusting device of machinery, for example mechanical brake is suitable for, and this mechanical brake acts on by the axle of drive motor and goes up or be fixed on the parts on this.Pneumatic adjusting device can be considered for example pneumatic braking device.As an alternative, can for example use brake of liquid braking device, eddy-current brake, electromagnetic action or the like according to another possibility of enumerating.At this preferably, the rotating speed modifier changes by means of electric, machinery, electromagnetism, pneumatic, hydraulic pressure and damper magnetic, preferred electromagnetism and drives rotating speed.CD-ROM drive motor can be corresponding to driving rotating speed high, especially described maximum (top) speed by in the grinding operation of vibromill and/or output running, at first dropping to described basic rotating speed by the damper of rotating speed modifier effect.Control or adjusting can perhaps reduce in check mode so that damping is cancelled in desired time, make the driving rotating speed that is produced rise to maximum (top) speed thus.Having such possibility as an alternative, regulate device itself and be applicable to that increase drives rotating speed, for example can be electronic, pneumatic or similar motor.Have such possibility, the rotating speed modifier is in operation automatically linear in desired time and/or rotating speed that change is non-linearly produced and the vibration that therefore changes the grinding unit in the predetermined curve according to relative set.According to curve, the resonance of grinding unit and output unit is carried out in the mode of determining, or begins controllably and finish once more controllably.Also have such possibility, the rotating speed modifier is designed to the module of vibromill.In automatic vibromill, the rotating speed modifier can be useful on periodically in grinding running and/or sample changes the module of the driving rotating speed of driver element from the discharge phase process of grinding unit.Substitute or make up preferably, vibromill has the cooling device that especially acts on the grinding wall that surrounds grinding chamber.For example can be useful on the cooling bath that cooling agent (as water) is flow through.This is not having under the situation of this cooling based on such cognition, is especially grinding in service for a long time because being heated of abrasive material and grinding chamber can appear in frictional heat, increases the tendency that adheres to thus.Therefore the cooling of passing through to be advised further contributes for reducing undesirable adhesion.
In addition, the present invention relates to a kind of operational shock mill, method of plate-like vibromill preferably of being used for, this vibromill has grinding unit and vibratory driver, and wherein, grinding unit can produce the vibration relevant with the driving rotating speed of vibratory driver by this vibratory driver excitation.
Start described technical problem from this paper, technical problem to be solved by this invention is, advantageously further develops this method, makes especially to avoid or reduce the adhesion of abrasive material in vibromill at least.
According to the present invention, this technical problem at first and mainly solves thus,, changes the driving rotating speed to predesignate mode in the vibromill running that is.Next effect that Shuo Ming feature is possible and advantage are with reference to above stated specification.At first preferably, drive rotating speed, preferably automatically change according to predetermined driving rotating speed-time graph.Have such possibility, effectively or the driving rotating speed that produces increase to selected maximum (top) speed from basic rotating speed one or many, this rotating speed greater than or approximate resonance speed, grinding unit is energized under resonance speed and produces resonance.Drive rotating speed and also can in desirable definite time period, remain on maximum (top) speed.In the advantageous embodiment of this method, drive rotating speed and can after increasing to maximum (top) speed, drop to basic rotating speed once more, and preferably in another time period, remain on basic rotating speed.In order to strengthen peeling off of bur, the driving rotating speed that is produced can periodically repeatedly rise to maximum (top) speed from basic rotating speed, and drops to basic rotating speed once more.In addition, preferably can automatically distinguish between grinding stage and output stage in method, in the described grinding stage, described abrasive material is pulverized, and exports from vibromill at the described abrasive material of described output stage.Preferably, effectively drive the basic rotating speed (it can have different or identical respectively values with output stage in the grinding stage) that rotating speed sets from correspondence at grinding stage and/or output stage and increase to maximum (top) speed more than or equal to resonance speed.For a change rotating speed preferably can use adjustment device electric, machinery, electromechanical, pneumatic, hydraulic pressure and/or magnetic, preferred electromagnetism.Driving the change of rotating speed can be advantageously realize, but also can at first initiatively improve the driving rotating speed of being set by CD-ROM drive motor by additional actuators as an alternative by means of electric, damper machinery, electromechanical, pneumatic, hydraulic pressure and/or magnetic, preferred electromagnetism.There is such possibility, the driving rotating speed of grinding unit and the therefore also linear and/or change non-linearly of vibration frequency.As an alternative or the combination, grinding unit, the grinding wall that preferably limits grinding chamber can be cooled.
