A shale shaker system. The system includes a fluid transport pipe configured to receive a stream of drill cuttings and fluid returns from a wellbore during a drilling operation; an analysis module configured to receive at least a portion of the stream of drill cuttings and fluid returns at an inlet; a cuttings chute configured to receive at least a portion of the stream of drill cuttings and fluid returns from an outlet of the container, and deliver them to a screen box; and one or more screens for filtering drill cuttings from the fluid returns. The analysis module comprises logging sensors configured to operate while drill cuttings are moving through the system. The logging sensors communicate with a processor to determine characteristics of the drill cuttings in real time. A method for analyzing drill cuttings at a well site is also provided.

A screening apparatus includes a vibrating screen assembly that includes a screen and a vibrating mechanism operable on the screen to cause vibration of the screen, the screen having a feed end and a discharge end. At least one shield member is positioned on the screen and is configured to cover part of the screen between the feed end of the screen and a position intermediate the feed and discharge ends of the screen, such that particulate material for screening by the screen can be fed on to the, or each, shield member, the, or each shield member being positioned on the screen so that a vibrational pattern of the screen is imparted to the shield member. An adjustment mechanism is operatively engaged with the, or each, shield member to adjust a position of a discharge end of the, or each, shield member relative to the discharge end of the screen.

A quantitative infrared chemical imaging method to determine the concentration of a desired high value product in a milling process is used as a basis to optimize the milling process by changing operational parameters, such as sieve size. In a dry milling process, the method can be used to determine the concentration of purified endosperm within heterogeneous solid particulate mixtures containing endosperm and nonendosperm botanical parts. The imaging component accommodates the analysis of particle size statistics for each component of the mixture, based upon the chemical structural characterization. Timely chemical composition and particle size analyses enables informed selection for the optimization of physical separation for the processing of granular solids. The method involves changing sieves within the sifting apparatus based on chemical imaging to provide smaller or larger screen openings to improve separation of endosperm and nonendosperm material from the ground product.

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 classifies materials utilizing a vision system that implements a machine learning system, such as a neural network, in order to identify or classify each of the materials as either a monetary coin or not a monetary coin, which may then be sorted into separate groups based on such an identification or classification. Such a system can sort monetary coins from other forms of scrap, which may have been produced from a shredding of end of life vehicles.

A screening system for separating/screening a conveying medium formed as fluid, powder and/or bulk material comprising a screening system inlet, a screening system outlet, a screen between the inlet and outlet, a feeding system for feeding the medium upstream of the inlet and/or the screen, a transport path between the inlet means and the outlet means, which is delimited by a conveyor channel line, a flow-limiting means wherein the volume flow of the conveying medium can be changeably limited is arranged in or down-stream from the transport path that comprises a flat transport surface, which is formed as a flat metering plate and a metering plate edge forms the outlet means of the feeding system, the flow-limiting means comprises an outlet opening wherein the outlet opening size can be changed to change the volume flow of the medium, which passes through the outlet opening that is arranged at the end of a conveyor channel or line of the feeding system, the outlet opening is arranged between the conveyor channel or line and the outlet means, in particular upstream of or on the transport surface and an oscillation can be applied to the medium.

There is provided a system for monitoring a screening machine, comprising a vibration sensor configured to record a vibration response of a screen fabric of the screening machine; and a signal processing device for digitally processing and evaluating the vibration response. In this connection, the signal processing device comprises an adaptive algorithm which is based on the methods of artificial intelligence, is related to vibration responses of one or several comparative screen fabrics and is adapted to characterize the vibration response recorded by the vibration sensor. Furthermore, a method for monitoring a screening machine is presented.

Disclosed is an inclined mobile screen for processing road building materials which provides for easy reconfiguration of the screen from operation configuration to a transport configuration and to a maintenance configuration, which allows for increased clearance between the screen and a feed conveyor without requiring a hydraulic actuator disposed therebetween. Nested telescopic supports are selectively coupled together in an offset connection to allow changes in the orientation of the screen to result in changes in the separation between the screen and the conveyor so as to allow for more clearance therebetween during time of maintenance.
