The present invention relates to a rock processing machine having functional units that are activatable and deactivatable, and having a control panel (50) that switches the rock processing machine, in a starting switching operation, from a less-active operating state into a more-active operating state with more activated functional units and, in a stopping switching operation, switches it from a more-active operating state into a less-active operating state with fewer activated functional units; the control panel (50) comprising a plurality of state switching elements (74, 80, 94, 96) with which, for at least one functional unit, a state transition is associated in such a way that actuation of the state switching element (74, 80, 94, 96) on the functional unit brings about a state transition. According to the present invention, only exactly one state transition is associated with each state switching element (74, 80, 94, 96) for at least one functional unit, so that a first set (58) of switching elements (70, 72, 74, 80) participates in the starting switching operation, and a second set (60) of switching elements (94, 96), different from the first, participates in the stopping switching operation; each set (58, 60) being arranged in a visually and/or haptically perceptible spatial arrangement relationship that corresponds to a predetermined actuation sequence of the switching elements (70, 72, 74, 80, 94, 96) of the respective set (58, 60).

A minerals processing unit, such as a vibrating screen (10), is described. The vibrating screen (10) comprises a sensing mechanism operable to detect: (i) motion of the vibrating screen (10) in multiple directions, and (ii) detect planar deviations of a mesh surface (22). The sensing mechanism may comprise a plurality of discrete sensors (60-66), including a gyroscopic sensor (60) operable to detect linear movement in three mutually orthogonal directions, and one or more of roll, pitch, and yaw. The sensing mechanism may further comprise a temperature sensor (64a, 64b) for measuring the temperature of a drive mechanism (42) and an ambient temperature sensor (66a, 66b) for measuring a control value to compare with the drive mechanism temperature.

A method of valuation of raw fines materials, comprising selectively screening, biotreatment or composting of raw fines materials or selection as fillers in composites. The method comprises screening the raw fines materials to Grade 1 comprising fines materials of a size of at most about 5 mm and Grade 2 comprising fines materials of a size larger than about 5 mm; and at least one of: A) bio-oxydating organic contaminants of the Grade 1; by adding and mixing organic amendment under controlled temperature, nutrients content and water content conditions and monitoring a content of organic contaminants until the content of organic contaminants stops decreasing; and B) composting the Grade 1; by adding and mixing organic amendment under controlled temperature, nutrients content and water content conditions, and monitoring pathogens content and respiration rate; and stopping the addition of organic amendment upon detection of absence of pathogens at a predetermined respiration rate.

A system for cleaning, repairing, and/or replacing damaged shaker screens is disclosed. The system may comprise a shale shaker with a replaceable shaker screen, at least one camera, and a computer processor. The camera is positioned to capture images of the shale shaker screen and the processor is capable of receiving said images from the camera. The processor is configured to analyze the images and detect damaged regions of the shale shaker screen. The processor is also configured to determine when a screen is damaged above a pre-defined threshold. Certain embodiments allow for the automatic cleaning, repair, and/or replacement of the shaker screen.

A material separation system is disclosed that may include a vibratory shaker, a centrifuge, a sensor, and/or a processor circuit. The vibratory shaker may be configured to separate a solid-liquid mixture into a first solids-containing component and a shaker effluent. The sensor may be configured to measure a property of one or more of the solid-liquid mixture, the first solids-containing component, the shaker effluent, and the second solids-containing. A well-performance analysis system may be configured to analyze mud reports of drilling rigs within a geographic basin to determine which rigs are performing inefficiently. The system may allow recommendations and send control signals to improve the efficiency of the solid-liquid separation system. The system may allow an operator to view agglomerated well performance data to identify which rigs are performing below a geographic basin baseline and make informed decisions to improve the functioning of a solid-liquid separation system associated with one or more drilling rigs.
