Abstract

A rock processing apparatus is provided for crushing and/or sorting granular mineral material according to size. The rock processing apparatus comprises a material feeding apparatus including a material buffer, at least one working unit of at least one crushing apparatus and at least one screening apparatus, at least one conveyor apparatus for conveying material between two apparatus components, a control unit for controlling apparatus components, at least one sensor for detecting at least one operating parameter, the sensor being connected to the control unit for transmitting a detection signal, at least one output device for outputting information and connected to the control unit. The control unit is designed to ascertain, in an operation with discontinuous material feed, and based on the at least one detection signal, time information about a future material feed, wherein the output device is designed to output the ascertained time information.

First claim

What is claimed is:

1 . A rock processing apparatus, comprising:
a material feeding apparatus having a material buffer configured to load starting material to be processed; at least one working unit; at least one conveyor apparatus configured to convey material between apparatus components; at least one sensor configured to transmit a detection signal representing an execution time of a future material feed into the material feeding apparatus; a control unit connected to the at least one sensor and configured to
ascertain, in an operation with discontinuous material feed of starting material to be processed, time information based on the at least one detection signal and representing an execution time of a future material feed into the material feeding apparatus, and
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 ascertained time information.

2 . The rock processing apparatus of claim 1 , wherein the control unit is configured to ascertain, in the operation with discontinuous material feed, an individual execution time as time information for at least first and second successive future material feeds and to output the individual execution times respectively via the output device.

3 . The rock processing apparatus of claim 1 , further comprising:
an input device operatively connected to the control unit and configured, in the operation with discontinuous material feed, to ascertain the time information based on the at least one detection signal representing an execution time of a future material feed into the material feeding apparatus and information input into the input device.

4 . The rock processing apparatus of claim 1 , wherein the at least one sensor is configured to detect, and to transmit to the control unit detection signals representing, at least one operating parameter from the group consisting of: a fill ratio of the material buffer; a fill ratio of the at least one conveyor apparatus; a conveying speed of the at least one conveyor apparatus; a fill ratio of at least one working unit; a grain shape and/or a grain size and/or a 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 feed quantity of material to be fed or already fed; an operating load of at least one drive apparatus; an operating load of the at least one working unit; a working speed of the at least one working unit; a dimension of a crush gap of the at least one working unit; a mesh aperture of a screen of the at least one working unit; a size of a loading tool of a loading apparatus discontinuously loading the material buffer; and a quantity or proportion of non-crushable foreign material.

5 . The rock processing apparatus of claim 3 , wherein the control unit is configured to ascertain, in the operation with discontinuous material feed, the time information by taking into consideration information input into the input device and selected from the group consisting of: a setpoint fill ratio of the material buffer; a setpoint fill ratio of the at least one conveyor apparatus; a setpoint conveying speed of the at least one conveyor apparatus; a setpoint fill ratio of the at least one working unit; a setpoint dimension of a crush gap of the at least one working unit; a setpoint operating load of at least one drive apparatus; a setpoint operating load of the at least one working unit; a setpoint grain size and/or setpoint grain size distribution of fed and/or conveyed material; a setpoint quantity of returned oversize grain; a setpoint mesh aperture of a screen of the working unit; a type of fed and/or conveyed material; a size of a loading tool of a loading apparatus discontinuously loading the material buffer.

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 1 , wherein the control unit is configured to control the discontinuous material feed based at least in part on the ascertained time information.

8 . The rock processing apparatus of claim 1 , further 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, the output device configured to transmit output information comprising the time 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 having a material buffer configured to load starting material to be processed,
at least one working unit,
at least one conveyor apparatus configured to convey material between apparatus components,
at least one sensor configured to transmit a detection signal representing an execution time of a future material feed into the material feeding apparatus,
a control unit connected to the at least one sensor and configured to ascertain, in an operation with discontinuous material feed of starting material to be processed, time information based on the at least one detection signal representing an execution time of a future material feed into the material feeding apparatus, 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 ascertained time information; and
a loading apparatus configured to discontinuously load the material buffer of the rock processing apparatus, and comprising a receiving device, wherein the output device is configured to transmit output information comprising the time information to the receiving device.

11 . The machine combination of claim 10 , wherein the receiving device is configured to output the time 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 time information.

13 . The machine combination of claim 10 , wherein the control unit is configured to ascertain, in the operation with discontinuous material feed, an individual execution time as time information for at least first and second successive future material feeds and to output the individual execution times respectively via the output device.

14 . The machine combination of claim 10 , the rock processing apparatus further comprising:
an input device operatively connected to the control unit and configured, in the operation with discontinuous material feed, to ascertain the time information based on the at least one detection signal representing an execution time of a future material feed into the material feeding apparatus, and information input into the input device.
