Systems and methods associated with screening systems are provided. In one example implementation, a screening system has a plurality of screen panels. Each of the screen panels define a screening surface with one or more apertures configured to separate material. The system includes a panel node associated with each of the plurality of screen panels. The system includes a controller node associated with the screening system. The controller node is operable to communicate with each panel node. Each panel node can include one or more sensing elements. The panel node further comprises a communication circuit configured to wirelessly communicate information to the controller node.

A sheet manufacturing apparatus that shortens the time until the apparatus stops is provided. The sheet manufacturing apparatus has a sieve unit having at least part of material defibrated in a defibration process introduced thereto, moving at a first speed, and passing defibrated material through multiple openings disposed in the main section thereof; and a forming unit forming a sheet using precipitate that past through the openings of the sieve unit; the sheet manufacturing apparatus stopping the sieve unit with defibrated material that was introduced stored inside the sieve unit when production by the sheet manufacturing apparatus stops.

This disclosure is generally drawn to systems, devices, apparatuses, and/or methods, related to monitoring a shaker and monitoring a room in which shaker(s) operate. Specifically, the disclosed systems, devices, apparatuses, and/or methods relate to controlling an actuated arm to inspect, remove, replace, repair, clean the shaker and/or screen assemblies based on monitoring the shaker and its screen assemblies, and to adjust or maintain shaker(s) in a defined area such as the room in which shaker(s) operate. While the examples disclosed herein generally describe shakers for separating solids from fluids, the present disclosure contemplates that other separation equipment (e.g., machines for separating solids from other solids) may also be monitored and controlled by the systems and methods described herein.

A modular quality improvement process and quality improvement system for high density coal measures oil shale. The process comprises: performing separation on the material with a particle size larger than 13 mm by an air dense medium fluidized bed, performing separation on the material with a particle size equal to or less than 13 mm and larger than 6 mm by an air dense medium fluidized bed, performing separation on the material with a particle size equal to or less than 6 mm and larger than 3 mm by a vibrated dense medium fluidized bed, and performing separation on the material with a particle size equal to or less than 3 mm by a vibrated fluidized bed, and recovery of a medium by magnetic separation for use as a circulating medium.

A material sorting system sorts materials utilizing a vision system that implements a machine learning system in order to identify or classify each of the materials, which are then sorted into separate groups based on such an identification or classification determining that the materials have a specified geometric shape. Such a system can sort monetary coins or other valuable metals from other forms of scrap.

A method for mechanically classifying polycrystalline silicon chunks or granules with a vibratory screening machine, involves setting silicon chunks or granules present on one or more screens each comprising a screen lining in vibration such that the silicon chunks or silicon granules perform a movement which causes the silicon chunks or silicon granules to be separated into various size classes, wherein a screening index is greater than or equal to 0.6 and less than or equal to 9.0.
