  • Patent number: 11325163
    Abstract: Systems and methods for sorting utilizing an inflatable actuator are disclosed. A sorting system utilizing an inflatable actuator includes an inflatable actuator. The inflatable actuator is disposed in a cantilever beam orientation atop a support surface. The system includes an inflation component coupled to the inflatable actuator to provide an inflation force. Additionally, the system includes a control component configured to send an activation signal to the inflation component responsive to a detection of an object to be sorted. Responsive to the activation signal, the inflation component inflates the inflatable actuator to cause the inflatable actuator to make contact with the object to be sorted. The contact of the inflatable actuator with the object to be sorted causes the object to change from a first trajectory to a second trajectory.

  • Patent number: 11292009
    Abstract: A gypsum washer includes a rotating trommel receiving raw material and a flow of water, and having paddles tilted to reduce impacts of the gypsum passing through the trommel while still providing a washing action. Bentonite separates from the gypsum in the trommel, liquifies, and is released through a mesh screen at the end of the trommel separating from the gypsum. The gypsum is released from the trommel into a water fed trough, scooped from the trough, and released into a storage area. The liquified bentonite is carried by a water flow into one or more settlement tanks, and recovered for use.

  • Patent number: 11286616
    Abstract: A screen machine for resolving a raw material concentration phenomenon occurring in the screen machine, a casing body for the screen machine, and a screen basket. A diluent supplied through an external pipe enters a casing diluent pocket of a casing body. The diluent then enters a diluent supply path by passing through a diluent entrance of the screen basket through one or more casing diluent supply paths located in a casing upper flange and flows into a diluent pocket through a diluent exit of the screen basket by passing through the diluent supply path. The flowing diluent is sprayed onto a concentrated raw material through one or more open diluent spray holes formed on a spray surface of the diluent pocket. Since the concentrated raw material is diluted, the concentrated raw material can be lowered to a desired concentration, and problems of conventional screen machines can be resolved.

  • Patent number: 11278913
    Abstract: Systems and methods for separating materials and recovery of valuable copper from shredded end-of-life vehicles and appliances are disclosed. Shredded matter, or ASR, is sent through a series of sorters before reaching a system that separates out copper bits. The system utilizes a pair of conveyor belts; one for de-watering and removing most of the plastic and glass particles and a second below the first for separating the copper bits. The second conveyor belt has a belt with a particular tooth pattern and material softness, and is set at a slight uphill incline angle. Water is delivered from the top down the slope and the belt successfully transports mostly just copper up and over a top edge to a collection bin. A cascading series of pairs of conveyors may be used to ensure nearly complete recovery of the copper.
