Abstract

The present disclosure relates to a rock processing apparatus for crushing and/or sorting granular mineral material according to size, comprising: a material feeding apparatus including a material buffer, the material feeding apparatus having an overall feed area, at least one working unit of at least one crushing apparatus and at least one screening apparatus, at least one conveyor apparatus, a control unit, at least one sensor for detecting at least one operating parameter, the sensor being connected to the control unit, at least one output device for outputting information. The control unit is designed, in an operation with discontinuous material feed of starting material to be processed, to ascertain a local target subarea within the overall feed area, selected for the next material feed, on the basis of the at least one detection signal as location information, and to transmit the location information to the output device.

First claim

What is claimed is:

1 . A rock processing apparatus for crushing and/or for sorting granular mineral material according to size, the rock processing apparatus comprising:
a material feeding apparatus including a material buffer configured to be loaded with starting material to be processed, the material feeding apparatus having an overall feed area, through which a test specimen represented by its center of gravity falls freely and unhindered to reach the material buffer; at least one working unit comprising at least one crushing apparatus and/or at least one screening apparatus; at least one conveyor apparatus configured to convey material between apparatus components; at least one sensor configured to detect at least one operating parameter, and to transmit a detection signal representing the at least one detected operating parameter; a control unit connected to the at least one sensor and configured
in an operation with discontinuous material feed of starting material to be processed, to ascertain a local target subarea within the overall feed area, selected for the next material feed, based on the at least one detection signal as location information, and
to control apparatus components of the rock processing apparatus; and
at least one output device connected to the control unit and configured to transmit output information comprising the location information received therefrom.

2 . The rock processing apparatus of claim 1 , comprising an input device configured to input information, and connected in signal-transmitting fashion to the control unit, the control unit configured in the operation with discontinuous material feed to ascertain the location information based on the at least one detection signal and a piece of information input into the input device.

3 . The rock processing apparatus of claim 1 , wherein the at least one sensor is configured to detect, and transmit signals representing, at least one operating parameters from the group consisting of: a fill ratio of the material buffer; in each case one local area fill ratio of at least two different areas of the material buffer; a fill ratio of at least one conveyor apparatus; a fill ratio of at least one working unit; a grain shape and/or grain size and/or grain size distribution of fed and/or conveyed material; a type of fed and/or conveyed material; a humidity of the fed material; a density of the fed material; a hardness of the fed material; a crushability of the fed material; an abrasiveness of the fed material; a state of the fed material; a quantity of returned oversize grain; a size of a loading tool of a loading apparatus discontinuously loading the material buffer; a feed quantity of material to be fed or already fed; a conveying speed of at least one conveyor apparatus; a working speed of at least one working unit; a quantity of material already processed by the rock processing apparatus, but returned into the material buffer; a quantity or proportion of, in particular non-crushable, foreign material.

4 . The rock processing apparatus of claim 2 , wherein the control unit is configured to ascertain, in the operation with discontinuous material feed, the location information by taking into consideration at least one piece of information input into the input device and selected from the group consisting of: setpoint fill ratio of the material buffer; in each case one local setpoint area fill ratio of at least two different areas of the material buffer; setpoint grain size and/or setpoint grain size distribution of fed and/or conveyed material; type of the rock processing apparatus; type of fed and/or conveyed material; type of the loading apparatus discontinuously loading the material buffer; size of a loading tool of the loading apparatus discontinuously loading the material buffer; and feed quantity of material to be fed or already fed.

5 . The rock processing apparatus of claim 1 , wherein the control unit is configured to ascertain, in the operation with discontinuous material feed, the location information by taking into consideration at least one piece of information retrieved from a memory device and comprising a type of the rock processing apparatus.

6 . The rock processing apparatus of claim 1 , wherein the output device is configured to output information independently of a receiver in a spatial area surrounding the rock processing apparatus at least partially and/or adjoining the rock processing apparatus.

7 . The rock processing apparatus of claim 6 , wherein the output device comprises a projection device configured to indicate in a visually perceptible manner the target subarea within the overall feed area.

8 . The rock processing apparatus of claim 1 , comprising a receiving device developed separately of a machine body of the rock processing apparatus and movable relative to the machine body and separable or separated from the machine body, wherein the output device is configured to transmit the location information to the receiving device.

9 . The rock processing apparatus of claim 8 , wherein the receiving device is a portable receiving device.

10 . A machine combination comprising:
a rock processing apparatus comprising
a material feeding apparatus including a material buffer configured to be loaded with starting material to be processed, the material feeding apparatus having an overall feed area, through which a test specimen represented by its center of gravity falls freely and unhindered to reach the material buffer,
at least one working unit comprising at least one crushing apparatus and/or at least one screening apparatus,
at least one conveyor apparatus configured to convey material between apparatus components,
at least one sensor configured to detect at least one operating parameter, and to transmit a detection signal representing the at least one detected operating parameter,
a control unit connected to the at least one sensor and configured
in an operation with discontinuous material feed of starting material to be processed, to ascertain a local target subarea within the overall feed area, selected for the next material feed, based on the at least one detection signal as location information, and
to control apparatus components of the rock processing apparatus,

at least one output device connected to the control unit and configured to transmit output information comprising the location information received therefrom; and
a loading apparatus configured to discontinuously load the material buffer of the rock processing apparatus, and comprising a receiving device situated therein, wherein the output device is configured to transmit output information comprising the location information to the receiving device.

11 . The machine combination of claim 10 , wherein the receiving device is configured to output the location information graphically and/or acoustically to a display device of the loading apparatus.

12 . The machine combination of claim 10 , wherein the receiving device is configured to control a transport-relevant operating component of the loading apparatus, based at least in part on the location information.

13 . The machine combination of claim 10 , comprising an input device configured to input information, and connected in signal-transmitting fashion to the control unit, the control unit configured in the operation with discontinuous material feed to ascertain the location information based on the at least one detection signal and a piece of information input into the input device.

14 . The machine combination of claim 10 , wherein the at least one sensor is configured to detect, and tr
