A spreader roll for a distributing device for granular material or fibers, the spreader roll having a load-bearing cylindrical core, and being rotatably mountable to a frame of the distributing device. At least part of the outer circumference of the core is provided with a plastics trimming fitted with bristles and/or pins, the plastics trimming being tubular and being non-destructively detachably mounted to the core and secured against rotation.

An adjustable roll sizer for sorting objects of different sizes includes a first set of rollers mounted to a support structure and arranged in a first parallel array. A second set of rollers is mounted to the support structure in a second parallel array that is interleaveably alignable with the first parallel array. Means for automatic control are provided for misaligning the second parallel array from the first parallel array to vary gap width between adjacent rollers. Each roller in the second parallel array may also be tapered to vary gap width as a function of roller length. Rollers may include helical ridges for urging objects along the gaps.

The present disclosure provides methods and systems for autonomous data collection and system control of a material recovery facility (MRF). A control system receives data from set of sensors that reflect a status of the MRF. The control system determines an operating status of various MRF components (e.g., material handling units (MHUs), sensors, and/or other elements) and/or a composition of a waste stream being processed by the MRF. The control system controls MHU(s) based on the data to optimize the recovery and/or purity of recoverable materials from the waste stream. The control system may rearranging MHUs within the MRF and/or re-tasking individual MHUs to perform different handling functions. Machine learning (ML) and/or artificial intelligence (AI) mechanisms can be used to optimize the operation of the MRF in an autonomous fashion. Other aspects are also disclosed.

Systems and methods for separating harvested crop product from twigs, dirt, dust, and other debris. A disk to be used in a harvester includes a first segment and a second segment and is configured to cooperate with adjacent disks axially mounted on a common rotational shaft, and radially cooperate with disks mounted on a parallel rotational shaft. The disks are used in a roller assembly or a harvester, and gaps between cooperating disks remain effectively constant during operation.

An adjustable grizzly grid material separator is provided and includes a plurality of flexible tines, a cassette, wherein the plurality of flexible tines are each coupled on an end to the cassette to form a grizzly assembly. A plurality of grizzly assemblies may be coupled to a frame at an angle, wherein the grizzly assemblies are coupled to the frame in a grid configuration. The plurality of tines are spaced apart a predetermined distance to set the size of material that is to be separated from an amount of aggregate flowing over the tines.

The invention relates to a device for sorting particulate materials of different grain size that can be part of a construction machine or digger's scoop. The device for sorting has a plurality of helical rollers, each exhibiting at least one helix, wherein each helical roller rotates about a rotary axis of its own, at least two adjacent helical rollers exhibit the same direction of rotation, and the rotary axes of at least three helical rollers are not arranged in a common plane. At least some of the helical rollers are held and rotatably mounted exclusively at one end.

A sorting device for sorting out coins from bulk material, includes at least one sorting gap (5) for coins that is limited by at least one roller (2) which can be rotated by a drive (33) about an axis of rotation (A) such that objects that cannot be conveyed through the sorting gap (5) are applied with force by the roller (2) in a direction away from the sorting gap (5) wherein a discharge hood (6) is provided for an eddy current separator device (29), which has an adjustable trajectory separator unit (4) in a hood interior (7), wherein the at least one roller (2) is arranged in or on the discharge hood (6) in relation to the trajectory separator unit (4) such that a non-ferrous metal fraction separated from the bulk material by the trajectory separator unit (4) is guided in the direction of the sorting gap (5) by the weight force of the non-ferrous metal objects (12).
