[0071] FIG. 3 shows a schematic representation of an arrangement of several mineral machining plants, and

[0072] FIG. 4 shows a schematic representation of a further block diagram.

DETAILED DESCRIPTION

[0073] FIG. 1 shows a mineral material machining plant in the form of a mobile mineral material crusher 10. The mineral material crusher 10 has undercarriages 15.

[0074] The mineral material crusher 10 has a chassis 11 that supports the machine components or at least part of the machine components. At its rear end, the chassis 11 has a cantilever 12. A material feed area is formed in the area of the cantilever 12.

[0075] The material feed area includes a feed hopper 20 and a material feed device 16.

[0076] The feed hopper 20 may be formed at least in part by hopper walls 21 extending in the longitudinal direction of the crusher 10 and a rear wall 22 extending transversely to the longitudinal direction. The feed hopper 20 leads to the material feed device 16.

[0077] As shown in this exemplary embodiment, the material feed device 16 may have a conveyor chute that can be driven by means of a vibratory drive. The feed hopper 20 can be used to feed material to be broken into the crusher 10, for instance using a wheel loader, and to feed it onto the conveyor chute.

[0078] From the conveyor chute, the material to be broken passes into the area of a screen unit 30. This screen unit 30 may also be referred to as a pre-screening arrangement. At least one screen deck 30.1, 30.2 is disposed in the area of the screen unit 30. In this exemplary embodiment two screen decks 30.1, 30.2 are used.

[0079] A partial fraction of the material to be broken is screened out at the upper screen deck 30.1. This partial fraction already has a sufficient particle size that it no longer needs to be broken in the crusher 10. In this respect, this screened out partial fraction can be routed past a crusher unit 40 through a bypass channel 31.

[0080] If a second screen deck 30.2 is used in the screen unit 30, a further fine particle fraction can be screened out from the partial fraction that accumulates below the screen deck 30.1. This fine particle fraction is routed to a lateral discharge conveyor 32 below the screen deck 30.2. The fine particle fraction is diverted from the lateral discharge conveyor 32 and conveyed to a rock pile 70.2 located at the side of the machine.

[0081] As FIG. 1 illustrates, the screen unit 30 may be a vibrating screen having a screen drive 33. The screen drive 33 causes the screen deck 30.1 and/or the screen deck 30.2 to vibrate. Owing to the inclined arrangement of the screen decks 30.1, 30.2 and in conjunction with the vibration motions, material on the screen decks 30.1, 30.2 is transported towards the crusher unit 40 or towards the bypass channel 31.

[0082] The material to be broken routed from the screen deck 30.1 is fed to the crusher unit 40, as shown in FIG. 1.

[0083] The crusher unit 40 may, for instance, be in the form of a rotary impact crusher unit, a cone crusher unit, or a gyratory crusher unit. The crusher unit 40 is designed in the form of a rotary impact crusher unit. The crusher unit 40 then has a crushing rotor 42 driven by a motor 41. In FIG. 1, the axis of rotation of the crushing rotor 42 is horizontal in the direction of the image depth.

[0084] For instance, the outer periphery of the crushing rotor 42 may be equipped with impact bars 43. Opposite from the crushing rotor 42, for instance, wall elements may be disposed, preferably in the form of impact rockers 44. When the crushing rotor 42 is rotating, the impact bars 43 throw the material to be broken outwards. In so doing, this material hits the impact rockers 44 and is broken due to the high kinetic energy. When the material to be broken is of sufficient particle size to allow the material particles to pass through the crushing gap between the impact rockers 44 and the radially outer ends of the impact bars 43, the broken material exits the crusher unit 40 through the crusher outlet 45.

[0085] It is conceivable that in the area of the crusher outlet 45, the broken material routed from the crusher unit 40 is combined with the material routed from the bypass channel 31 and transferred onto a belt conveyor 13 (crusher discharge conveyor). The belt conveyor 13 can be used to convey the material out of the working area of the crusher unit 40.

[0086] As shown in the drawings, the belt conveyor 13 may comprise an endless circulating conveyor belt having a slack side 13.3 and a tight side 13.4. The slack side 13.3 is used to catch and transport away the crushed material falling from the crusher outlet 45 of the crusher unit 40. At the belt ends, deflection rollers 13.1, 13.2 can be used to deflect the conveyor belt from slack side 13.3 to tight side 13.4 and vice versa. Guides, in particular support rollers, can be provided in the area between the deflection rollers 13.1, 13.2 to change the conveying direction of the conveyor belt, to shape the conveyor belt in a certain way and/or to support the conveyor belt.

[0087] The belt conveyor 13 has a belt drive, which can be used to drive the belt conveyor 13. The belt drive can preferably be disposed at the discharge end 13.5 or in the area of the discharge end 13.5 of the belt conveyor 13.

[0088] The belt conveyor 13 can be connected, for instance by means of the belt drive, to a control device by means of a control line.

[0089] One or more further belt conveyors 60 and/or a return conveyor 80 may be used, which in principle have the same design as the belt conveyor 13. In this respect, reference can be made to the above statements.

[0090] A magnet 14 can be disposed above the slack side 13.3 in the area between the feed end and the discharge end. The magnet 14 can be used to lift iron parts from the broken material and move them out of the conveying area of the belt conveyor 13.

[0091] A re-screening device 50 can be disposed downstream of the belt conveyor 13. The crusher unit 50 has a screen housing 51, in which at least one screen deck 52 is mounted. Below the screen deck 52, a housing base 53 is formed, which is used as a collection space for the material screened out at the screen deck 52.

[0092] An opening in the lower housing part 53 creates a spatial connection to the further belt conveyor 60. Here, the further belt conveyor 60 forms its feed area 61, wherein the screened material in the feed area 61 is directed onto the slack side of the further belt conveyor 60. The further belt conveyor 60 conveys the screened material towards its discharge end 62. From there, the screened material is transferred to a rock pile 70.1.

[0093] The material not screened out at the screen deck 52 of the re-screening device 50 is conveyed from the screen deck 52 onto a branch belt 54. The branch belt 54 can also be designed as a belt conveyor, i.e., reference can be made to the explanations given above with respect to the belt conveyor 13. In FIG. 1, the transport direction of the branch belt 54 extends in the direction of the image depth.

[0094] At its discharge end, the branch belt 54 transfers the un-screened material, also referred to as oversize material, to the feed area 81 of the return conveyor 80. The return conveyor 80, which may be a belt conveyor, conveys the oversize material towards the feed hopper 20. At its discharge end 82, the return conveyor 80 transfers the oversize material into the material flow, specifically into the material feed area. The oversize material can therefore be returned to the crusher unit 40 and crushed to the desired particle size.

[0095] As FIG. 1 further shows, an input unit 90 is assigned to the mineral material crusher 10. The input unit 90 may be permanently secured to or separate from the mineral material crusher 10. In particular, the input unit may be in wired or radio communication with a processing device 100 of the mineral material crusher 10 for the purpose of exchanging data. It is also conceivable that the processing device 100 is not part of the mineral material crusher 10, but that it is part of a decentralized unit that is connected to the input unit 90 and to the mineral material crusher 10 for the purpose of exchanging data. Furthermore, it is conceivable that the processing device 100 is part of the input unit 90.

[0096] The processing device 100 is connected to a control device of the mineral material crusher 10, wherein data can be transferred from the processing device 100 to the storage device (and preferably vice versa).

[0097] FIG. 2 illustrates a process according to the invention in more detail. With this method, it is possible to generate target machine parameters SP or a target machine parameter set with one or more target machine parameters SP in the processing device 100. These data can then be transferred to a control device 130 of the mineral material crusher 10.

[0098] As this representation illustrates, a characteristic machine value Ktyp may be entered into the input unit 90 and transferred to the processing device 100.

[0099] For a user-friendly guidance, provision can be made, for instance, for the characteristic machine value Ktyp to be selected from a list that characterizes available machines according to their typification. For instance, a selection list can be displayed showing “impact crushers”, “cone crushers”, “jaw crushers”, “gyratory crushers”, or “screening machines” as selection options. The user can then select one of these types to use it to enter the characteristic machine value Ktyp into the input unit 90.

[0100] It is also conceivable that the mineral material machining plant, in particular the mineral material crusher 10 is determined based on its design in a selection list. This may involve displaying manufacturer-specific labels in a drop-down list, which can then be selected by the user. Finally, it is also conceivable that an individual machine identification is entered into the input unit 90 as the characteristic machine value Ktyp.

[0101] Preferably, the operator is shown available possible machines in one or more selection lists from which a machine can be selected.

[0102] Furthermore, a characteristic material value of the feed material KM to be machined may be entered to the input unit 90 and transferred to the processing device 100.

[0103] Preferably, the operator is shown available characteristic material values of the feed material KM in one or more selection lists, from which at least one can be selected.

[0104] Then the selection of the material to be machined can be made from a list that qualitatively divides the material to be machined into different categories, for instance. An example of this is the classification as follows: “Hard rock, soft rock, reinforced concrete, asphalt, construction debris, gravel, track ballast.” From these options, the user can select one to enter the characteristic material value of the feed material KM into the input unit 90 to transfer this value or a value correlating with this input value to the processing device 100.

[0105] It is also conceivable that the material to be machined is qualitatively divided into different hardness categories. An example of this is the classification as follows: “soft, hard, very hard, etc.” From these options, the user can select one to enter the characteristic material value of the feed material KM into the input unit 90 such that this value or a value correlated thereto is transferred to the processing device 100. It is also conceivable that hardness categories are specified in the form of specific hardness value ranges. It is also conceivable that specific hardness values of the feed material can be entered into the input unit 90.

[0106] It is conceivable that a selection list contains qualitative or quantitative categories from which the user can select an entry. In particular, it is conceivable that the operator can make a selection of the characteristic material value or values of the feed material KM from various characteristic values of a selection list, which qualify or quantify the material size of the feed material. For instance, possible grain sizes and/or the grain size distributions of the feed material can be displayed in a selection list and the user can make a selection from this list. It is also conceivable that the user enters a specific input value into the input unit 90 as the characteristic material value of the feed material KM, which individually specifies the grain size or the grain size distribution of the end material.

[0107] Furthermore, it may be feasible, in an additional step, that an abrasion characteristic value KA is entered into the input unit 90 as a characteristic material value of the feed material KM to be machined and is transferred to the processing device 100.

[0108] Preferably, the operator is shown one or more selection lists of available material characteristics of the feed material KA, from which at least one can be selected.

[0109] Again, the selection list may contain a qualitative categorization from which the user can select an entry. For instance, a qualitative categorization may be as follows: “high abrasiveness, medium abrasiveness or low abrasiveness”. It is also conceivable that a qualitative categorization is included in a selection list, wherein certain abrasiveness ranges are predetermined as selection points, one of which can be selected by the user to enter the abrasiveness characteristic value KA into the input unit 90. Finally, it is also conceivable that an input mask is provided on the input unit 90, in which the user can enter a specific present abrasion characteristic value KA of the feed material.

[0110] Further, according to the invention, in one step, a characteristic material value of the end material KE to be produced is entered to the input unit 90 and transferred to the processing device 100.

[0111] Preferably, available characteristic material values of the end material KE to be produced are displayed to the operator in one or more selection lists, from which at least one can be selected.

[0112] Again, the selection list may contain qualitative or quantitative categories from which the user can select an entry. In this context, it is conceivable that the operator can make a selection of the characteristic material value or values of the end material KE from various characteristic values of a selection list, which qualify or quantify the material size of the end material to be produced. For instance, possible grain sizes and/or the grain size distributions of the end material can be displayed in a selection list and the user can make a selection from this list. It is also conceivable that the user enters a specific input value into the input unit 90 as the characteristic material value of the end material KE, which individually specifies the grain size or the grain size distribution of the end material.

[0113] Furthermore, it may be feasible, in a method step, that at least one characteristic value or information on the physical configuration EW of the mineral material machining plant, in particular the mineral material crusher 10 may be entered into the input unit 90, and transferred to the processing device 100.

[0114] Preferably, the operator is shown one or more selection lists of available tools, for determining the physical configuration EW. If the characteristic machine value Ktyp has already been entered in a previous step, it is now advantageous to display only those tools as available tools that are suitable for the specific machine or machine type.

[0115] If the characteristic material values of the feed material and the end material KM and KE have already been entered in a previous process step, then advantageously only those tools are now displayed as available tools which are suitable for the pending machining task to achieve the desired final result in principle.

[0116] The user can now select the appropriate options from the information displayed for the EW physical configuration, and enter them in the input unit. In other words, the user can now choose the desired tools from those proposed and those the user deems suitable, to obtain the desired physical configuration EW.

[0117] It is conceivable that eligible tools are categorized according to their properties. For instance, tools may be categorized by properties such as material, shape, wear resistance, geometric design, mesh size of a screen coating, material thickness, and so on.

[0118] In a subsequent correction step, a user can also make a correction to the physical configuration EW proposed, wherein single or multiple configuration proposals are corrected by entering a correction machine parameter. In other words, the physical configuration EW is changed in this way. This suggested change is entered into the input unit 90 and transferred to the processing device 100. There it is then determined whether the machining task at hand can be sensibly solved based on the desired correction machine parameter PC. If this is not possible, the user will receive an error message (not shown). In this case, the user is then offered the opportunity to change the physical configuration EW in the form of a correction loop.

[0119] If the input values are suitable to accomplish the crushing task at hand, at least one target machine parameter SP or a target machine parameter set comprising one or more target machine parameters SP is generated in the processing device 101. The target machine parameter SP or the target machine parameter set is then transferred to the control device 130 of the mineral machining plant, in particular of the mineral material crusher 10. The control device 130 then preferably automatically causes the setting of individual or all machine functions, based on the target machine parameters SP. Furthermore, it is conceivable that the user is shown how to configure the mineral machining plant and with which tools on a display device, for instance on the input unit 90. Subsequently, the mineral machining plant is then operated based on the specified target machine parameters SP.

[0120] It is also conceivable that the target machine parameter SP or the target machine parameter set in conjunction with at least the characteristic material value of the feed material KM and the characteristic material value of the end material KE are transferred in the form of a preset data set to a separate central data processing device 110, as shown by the dashed line in FIG. 2. The transmission can be performed for instance using a suitable wireless connection, for instance Internet connection, for which the mineral machining plant has a data interface 18 (see FIG. 1).

[0121] FIG. 3 shows a diagram illustrating several mineral machining plants, in particular a mineral material crusher 10. Each of these mineral machining plants is connected to a control center 120 via its data interface 18 to transfer the preset data set to be processed in the central data processing device 100 and stored in a memory unit 111.

[0122] In this way, preset data sets can be received from multiple mineral material machining plants, modified if necessary, and stored. In this way, a database is formed that holds preset data sets for specific upcoming machining tasks, which can then be made available to a mineral machining plant.

[0123] As FIG. 3 further illustrates, a position-transmitting device 17 may also be assigned to a mineral machining plant. This position-transmitting device 17 permits a mineral machining plant to determine its current position and transmit it to the control center 120. In a memory unit of the control center 120, position values may be correlated with one or more feed characteristic material values KM in a database.

[0124] Based on the position signal received from the position-transmitting device 17, the characteristic material value of the feed material KM present for the position of the mineral machining plant can then be determined from the database and transferred to the processing devices 100.

[0125] This is further specified in FIG. 4. As this representation illustrates, the position-transmitting device 17 is used to transfer the position data LOC. The central data processing device 110 then transfers the characteristic material value or values of the feed material KM, which may include the abrasion characteristic value KA.

[0126] Optionally, input facilities for entering the characteristic material value of the end material KE and for information on the physical configuration EW can also be provided at the input unit, as explained above. Furthermore, an option to enter a correction machine parameter PC can follow. To avoid repetitions, reference is made to the explanations above.

[0127] Subsequently, the at least one target machine parameter SP or the target machine parameter set is transferred to the control device 130 or the central data processing device 110 in the same manner as explained above with respect to FIG. 2.
