Definitions
- the invention relates to a method for setting the gap width of a cone crusher or the like with a wobbling revolving cone that is height-adjustable with respect to a crushing jacket and is moved into a reference position by approaching the crushing jacket, from which the path corresponding to a predetermined gap width starts - Piece is determined by which the crushing cone is distant from the reference position after moving into its working position, the approach to the crushing jacket being detected by a movement measurement and the respective crushing cone position being determined by means of a path measurement.
- the gap width i.e. the width of the crushing gap between the stationary crushing jacket and the concentric cone located in the interior of this crushing jacket and tumbling during operation is of crucial importance for the crushing effect and performance of a cone crusher or a similar type of crushers: With a smaller crushing gap, the crushing material is comminuted more finely than with a larger crushing gap. As a result of the wear on the crushing cone and crushing jacket occurring during operation, the width of the crushing gap changes, with the result that the crushed product gradually has an increasingly coarse grain. This undesirable development must be taken into account in that the
- the gap width is set again at least from time to time to a predetermined value.
- the inclination of the axis of the crushing cone means that, with corresponding transition areas, it has a minimum and a maximum distance from the stationary crushing jacket; the point forming the small bar distance is the width of the crushing gap.
- Crushing cone is brought away from the crushing jacket. Reaching the reference position is determined by a pressure sensor which is built into the circuit of the hydraulic slide drive for the crushing cone; the distance covered in the working position during the opening movement is determined by measuring a volume of liquid displaced by the opening movement.
- the width of the crushing gap and the extent of wear can be determined using an inductive displacement measurement; this is carried out by means of a measuring piston engaging more or less far into a coil.
- the known method can also be carried out automatically according to a predetermined program either after the crushing cone has been stopped or less frequently.
- a method for detecting and regulating the gap width of a cone crusher by electrical means is also known, for example, from German Offenlegungsschrift 20 51 398.
- the invention is based on the object of specifying a method (and the components required for its implementation) by means of which the accuracy in setting the width of the crushing gap is improved.
- the method should be such that, if possible, different signs of wear on the crushing cone and / or crushing jacket are also taken into account when setting the gap.
- the stated object is achieved by a method which at least essentially has the features of claim 1.
- the idea of the solution on which the invention is based consists in that, with the refractive cone rotating, several successive approximation cycles (each consisting of the refractive cone approaching the crushing jacket and subsequent opening movement away from the crushing jacket) and the approximation values obtained in each approach cycle for formation to use a reference value that defines the reference position, from which the position of the refractive cone is determined, which the latter should assume in the working position with regard to a desired gap width.
- the approximation processes taking place within the framework of the approximation cycles can either be carried out in such a way that the revolving crushing cone comes into contact with the crushing jacket for a short time or briefly (in particular over a layer of test material; cf. claim 9) in a small, reproducible distance from the crushing jacket is kept;
- the determination of the reference position according to the invention can therefore be based on the fact that either a brief touch (when the "zero" Gap width ”) or near contact (when the" almost zero gap width "is reached) between the crushing cone and the crushing jacket.” Movement measurement "in the sense of the method according to the invention (cf.
- the preamble of claim 1) to understand a measuring or scanning method or the like which reveals whether the crushing cone has in each case completed its approaching process within the predetermined number of approaching cycles, that is (if there is no fault) at the crushing jacket or near the crushing jacket to a standstill
- the acquisition of the process-relevant variables and the control of the associated components (drives, valves) is expediently carried out via a control unit, in which a computer equipped with sufficient storage capacity is integrated.
- the completion of the approach of the crushing cone directly to the crushing jacket or indirectly to it via a test material layer can - in particular inductively - via a speed measurement (claim 2) and / or a pressure measurement claim 3) - for example in the printing network a hydraulic shift drive for the crushing cone - be detected;
- the respective position of the crushing cone with respect to the stationary crushing material can be determined, for example, using the known displacement measuring methods mentioned at the beginning.
- the method is preferably designed in such a way that an average value is formed from the associated approximate values, which is the Represents reference value (claim 4); the reference value can in particular be calculated from the arithmetic or the quadratic mean of the associated approximate values.
- the method according to the invention can also be carried out in such a way that a certain approximation value is selected from the related approximation values as the reference value, specifically the one which has the greatest shift in the direction of the crushing ice in the direction determined in the context of the approximation cycles indicates on the crushing jacket (claim 5).
- the crushing cone is moved into a predetermined opening position, which deviates from the reference position (claim 6), at least after the end of each approximation cycle - possibly also before the first approximation cycle;
- the distance between the open position and the reference position can be kept constant (claim 7); This can be done, for example, by adapting the position of the open position to the change determined after determining the reference position. If the changing values for the position of the opening position or the reference position are stored and made recognizable in the form of a curve, the development of the wear in the associated time period (to which the can be assigned to individual positions) and also provide an indication of future wear development.
- the method can be designed in a favorable manner by comparing the stored opening position values or reference position values with a predetermined limit value; reaching this limit value serves - for example as an optical or acoustic - indication that the wearing parts of the cone crusher (crushing jacket, crushing cone) have to be replaced.
- the setting process runs in such a way that the supply of the crushing material into the cone crusher is first interrupted before the approximation cycles for determining the reference position in question run automatically with a sufficient time delay.
- the approach cycles and the subsequent shifting of the crushing cone into the operating position are preferably triggered automatically at preselectable time intervals, the first approach cycle starting with a time delay in order to interrupt the supply of crushing material (claim 8).
- the storage of the reference positions or the opening positions respectively adapted to them is also advantageous insofar as comparison with the stored position values (for example caused by foreign bodies) Incorrect measurements can be found and suppressed as unusable.
- the approaching processes always assume a constant, known opening position, it can also be checked on the basis of time measurements running in parallel whether the crushing cone has traveled at least a previously known distance to a standstill.
- the determination of the reference position can also take place in such a way that the crushing cone is only moved into the vicinity of the crushing jacket in the course of the approximation cycles.
- the individual approximation processes come to a conclusion as soon as the revolving crushing cone is supported on the crushing jacket by a layer of test material with known grain size - that is, only indirectly.
- the layer involved in the formation of the reference position can be produced by introducing a sufficient amount of test material into the crushing gap instead of the crushing material, at least during the approximation processes (claim 9).
- the process variant in question is advantageous in that the determination of the reference position takes place without contact between the rotating crushing cone and the stationary crushing jacket.
- the housing of the cone crusher 1, on which the method according to the invention is used, is set are composed of an upper housing part 2a with a feed opening 2b and an outlet opening 2c, a subsequent, only partially illustrated housing middle part 2d and a lower housing part 2e with an upward thrust bearing 2f.
- a crushing cone 3 is held rotatably and vertically adjustable within the housing, the exchangeable cone shell 3a of which forms a crushing gap 5 with a frustoconical crushing shell 4 which is exchangeably fastened to the upper housing part 2a.
- the crushing cone 3 is immovably supported on a shaft 7 by means of a fastening ring 6, which in turn is supported by a pendulum bearing 8 on the upper housing part 2a, by a radial bearing 9 in the form of a rotating drive housing on the middle housing part 2d and by means of its downward direction End face 7a on the height-adjustable piston 10a of a stationary hydraulic cylinder 10.
- the drive housing 9 which is equipped with a ring gear, rests on the axial bearing 2f and is connected to the pinion 12a of a three-phase motor 12 via a drive element in the form of a toothed belt 11. Due to the eccentric support of the shaft 7 in the drive housing 9, when the three-phase motor 12 is put into operation, the crushing cone 3 performs a wobbling movement within the crushing shell 4, the narrowest point between the parts 3a and 4 - the crushing gap 5 - rotating with respect to the crushing shell 4.
- the feed opening 2b is preceded by a conveyor unit 13 which consists of a hopper 13a, a conveyor driven by a conveyor motor 13b. derschnecke 13c and a in the feed opening 2b opening conveyor trough 13d.
- the conveyor motor 13b is connected via a control line 14 to a control unit 15, in which a computer 15a with sufficient storage capacity is integrated and which has a time control unit 15b for monitoring and controlling procedural steps in terms of time.
- the energy network for the hydraulic cylinder 10 consists of a motor-driven hydraulic pump 16, two remote-controlled valves 17 and 18, which are installed in the pressure line 19 or return line 20 of the hydraulic cylinder 10, and an oil tank 21, in which the lines 19 and 20 and the return line 17a of the valve 17 open.
- a pressure sensor 22 is connected upstream of the valve 17 in the direction of the hydraulic cylinder 10 and is connected to the control unit 15 via a measuring line 23.
- Components 16 to 18 are also connected to control unit 15 via control lines 24, 25 and 26, respectively.
- the respective position of the crushing cone 3 with respect to the stationary environment is detected by means of a displacement measuring unit which consists of a measuring part 27a attached to the shaft 7 and a stationary displacement measuring sensor 27b which is connected to the control device 15 via a measuring line 28 .
- a current measuring device 29 is assigned to the drive mentioned, the measured values of which are fed into the Control unit 15 can be entered and processed there.
- Certain data stored in the computer 15a can, if necessary, be made visible by means of a screen 31 connected to the control device 15.
- the control device has a manual switch 32.
- the conveyor motor 13b is first stopped via the control unit 15 and the control line 14 and the supply of crushing material into the area of the feed opening 2b of the cone crusher 1 is interrupted, while the crushing cone 3 continues to tumble and the crushing material still present is crushed.
- the measured value corresponding to the working position of the crushing cone 3 and detected by the displacement sensor 27b has already been stored in the memory 15a during the previous setting of the crushing cone in the current working position.
- the crushing cone 3 into a through the memory is, with a predetermined, adjustable time delay for actuating the manual switch 32 by closing the valve 17 and opening the valve 18 15a predetermined opening position lowered; the time delay is chosen so that the cone crusher 1 with sufficient security in the area of the components 3 and 4 no crushing material contains more, so it is empty.
- the crushing cone is briefly brought into contact with the crushing jacket 4 by suitable switching of the hydraulic pump 16 and the valves 17 and 18 in several successive approximation cycles and then returned to the predetermined opening position.
- the approximate values corresponding to the system on the crushing cone 4 are each detected by the displacement sensor 27b and stored in the computer 15a.
- the arithmetic mean value is formed from the determined approximation values, which represents the reference value that defines the reference position of the crushing cone and that is also stored.
- Gap distance corresponding distance determined by which the crushing cone must be located from the reference position is in turn - monitored by the displacement sensor 27b - effected by suitable adjustment of the piston 10a, which is locked in the position assumed after reaching the working position.
- the distance measurement corresponding to the working position is also saved.
- the approach of the crushing cone to the crushing jacket 4 is determined when the valve 18 is closed via the pressure sensor 22, which causes the pressure increase occurring in the energy network of the hydraulic cylinder 10 via the measuring line 23 into the control unit 15 inputs; this then, by suitable actuation of the valves 17 and 18, causes the crushing cone to return to the opening position already mentioned.
- the time control unit 15b can be used to assign the stored values for the reference position and / or the working position to the associated time intervals. In this way it is possible, for example, to display the stored values for the working position of the crushing cone, plotted over time, on the screen 31 and to obtain a statement about the wear that has previously occurred on the components 3a and 4 .
- the timing control unit 15b can also be used in cooperation with the distance measuring parts 27a, 27b to monitor the approaching processes during the approaching cycles. Insofar as there is no incorrect measurement, the crushing cone can only touch the crushing jacket 4 when the approximation process has ended, that is to say the distance measurement value detected by the displacement sensor 27b no longer changes with the time specified by the time unit 15b. By means of the interaction of the components 27a, b and 15b, erroneous measurements can be ruled out if it is checked at the same time by comparison with already stored approximate values whether the crushing cone has covered a minimum distance in the direction of the crushing jacket 4.
- the checking and setting of the gap width under the action of the time unit 15b can also be automated. triggered and carried out table.
- the time unit can be set so that it triggers the method according to the invention automatically once a day.
- the method according to the invention can in particular also be designed in such a way that, in addition to or instead of the pressure measurement by means of the pressure sensor 23, an inductive measurement method is used, as is known, for example, from the aforementioned German published application.
- an inductive measurement method is used, as is known, for example, from the aforementioned German published application.
- the displacement of the crushing cone into a predetermined working position can, however, also be carried out on the basis of a reference position in which the tumbling revolving crushing cone 3 only almost touches the crushing jacket 4.
- test material with known grain size is introduced into the feed opening 2b at least during the approach cycles of the cone crusher 1 after the approach cycles.
- the test material forms a layer in the gap area, over which the crushing cone is only supported indirectly on the crushing jacket after completion of the approach processes. This procedure is associated with additional effort; however, it has the advantage that a reference position of the crushing cone 3 can be determined via reference values without the latter having to touch the crushing jacket 4 during the successive approximation cycles.
- the position of the opening position is adapted to the changing reference position and the associated values are saved, a comparison can be made of the stored values with a limit value for the opening position to determine the extent of wear or whether the interacting wear parts 3a are replaced and 4 is required.
- the main advantage of the method according to the invention lies in the fact that the reference value, from which a predetermined working position of the crushing cone is controlled, is determined over several approximation cycles which represent tactile operations, specifically with the revolving crushing cone. Since several reference values are determined in chronological succession, non-uniform wear of the two interacting wear parts is also included in the reference value and thus influences the setting of the width of the crushing gap.
