A separation system suitable for separating a dry or dried infill preferably including rubber and/or sand, into a plurality of fractions, the separation system includes a first screening means configured to receive a first set of separation screens said set of separation screens being configured to separate infill into a first plurality of fractions, wherein the separation system further includes a pre-analysis unit, a database and a processing unit configured to calculate correlation coefficients and/or deviation values between the first set of composition values and a plurality of second sets of composition values of the database; and a method for separating a dry or dried infill having a composition of materials, preferably including rubber and sand, into a plurality of fractions.

In certain embodiments, the disclosure provides an inflatable bladder lid that configures with a cartridge configured for assay testing. The inflatable bladder provides substantially uniform pressure to the cartridge. The pressure is substantially distributed across the one or more regions of the cartridge to extend pressure over a wide cartridge surface. At least a portion of the bladder lid may comprise a flexible membrane material that inflates and stretches over at least a portion of the cartridge to conformally contact its first/top surface.

A sediment classification system enables the screening of material that enters a backhoe bucket. Material that enters the bucket exits through a duct with an opening at the back of the bucket. The material is screened by passing between a first set of bars and a second set of bars. The bars have spacers between them attached to one of the sets of bars. The second set of bars is pined to the first set and is able to move to clear material wedged between the bars.

Universal belted chain including a first belt, a second belt, a first rod, a first fastener and a second fastener. The first belt has a first upper surface and a first lower surface. The first lower surface has a first channel formed therein. The second belt has a second upper surface and a second lower surface. The second lower surface has a second channel formed therein. The first fastener attaches the first rod to the first upper surface by extending the first fastener through the first belt. An end of the first fastener opposite the first rod is recessed in the first channel with respect to the first lower surface. The second fastener attaches the first rod to the second upper surface by extending the second fastener through the second belt. An end of the second fastener opposite the first rod is recessed in the second channel with respect to the second lower surface.

An object sorting system is presented which includes a hopper, a feeder, a roller pair, a pair of orientation flaps, an adjustable assembly, a first and second camera boxes and an ejection assembly. Feeder receives the shells from the hopper and feeds them uniformly over the gap between the rollers which guides and provides fixed orientation to the shells passing through them and conveys the shells which are relatively bigger than the gap between the rollers to one side of the pair of rollers towards the first collection chute by inclining the roller assembly in the range of 0 to 15 degrees towards the first collection chute. A pair of orientation flaps is placed parallel and exactly below the pair of rollers to avoid the deflection of shells caused immediately after passing through the roller gaps.

The disclosure features material separators for screening excavated material (e.g., rocks from soil.) In some implementations the materials separators include (a) a supporting frame; (b) a screening surface mounted at an incline on the supporting frame, the screening surface comprising a plurality of fixed bars that are attached to the frame in a manner to resist upward movement, and a plurality of shift bars that are attached to the frame at their upper and lower ends, in a manner to allow upward movement; and (c) a shift bar actuator, positioned between the upper and lower ends of the shift bars, the shift bar actuator being configured to impart a two-stage movement to the shift bars, whereby during a first stage the upper ends are first displaced vertically, and during a second stage the lower ends pivot upward about the upper ends.

The present invention relates to an apparatus for grading sensitive products. The apparatus treat the objects to be graded gently and is accurate and may be constructed so as to handle extremely large quantities. The grading device of the present invention has grading channels that are wider at the outlet than at the intake. The belt machine draws the objects forward between two inclined belts which form the channel. An adjusting device is implemented perpendicular underneath the belts of the apparatus comprising alternatively arranged support members and adjusting members arranged on an adjusting screwing shaft. Both components comprise screwing sections which regulates an increase or a decrease in the gap between the support members when the adjusting screwing shaft is rotated.

A screening tool includes at least a first screen lining which is coupled to a metal coupling element to which an ultrasonic transducer is connected which is connected by electrical lines to an ultrasonic generator. The screening tool includes a metal work plate which has a connection region and at least one first transfer region with first transfer openings, which first transfer region forms the first screen lining through which particles of the process material which are larger than the transfer openings can pass, from particles of the process material smaller than the transfer openings, wherein the coupling element is a curved or straight rod having a first end piece welded to the connection region and a second end piece mechanically connected to the ultrasonic transducer. The screening device includes one or more such screening tools and a control unit by means of which the ultrasonic generator is controllable.
