  • Patent number: 10427167
    Abstract: A device for separating weakly magnetic first particles, for example hematite particles, from mixture (912) comprising the first particles (913) and less magnetic second particles (914) is presented. The device comprises first magnetizing equipment (901) for producing magnetic field and for moving the mixture so that mutually opposite polarity portions (N, S) of the magnetic field sweep the mixture in a sweeping direction and thereby deflect the direction of movement of the first particles towards the sweeping direction and away from the direction of movement of the second particles.

  • Patent number: 10393435
    Abstract: A dewatering device for aggregate product can be used to retro-fit existing aggregate product dewatering facilities in order to more efficiently capture product. The dewatering device can be movable to allow for the portability of the device relative to existing dewatering facilities. The device is adapted to receive a slurry of aggregate product and water and to vibrate to dry the aggregate product. A recycle system is included to receive any fines that may otherwise be lost by the system. The recycle system captures the fines and redirects them back towards the vibrating process of the vibrating device to direct them towards an exit of the vibrating device in order to use said fines as well as the other dewatered aggregate product. The portability of the device allows the device to be used with the existing facilities without the need to completely replace existing components for dewatering aggregate product.

  • Patent number: 10384233
    Abstract: Disclosed is a material separation apparatus with a circular ore separation wheel and a number of projected spiral portions, tilted towards a central hole, provided on a concave shaped interior surface. A pair of adjacent projected spiral portions forms less than 90 degree angle to create a negative draft for an upward movement of the heavy materials during rotation of the circular ore separation wheel. The central hole of the circular ore separation wheel is attached with a central hub to rotate the circular ore separation wheel to trap the collected heavy materials in between the adjacent projected spiral portions. The circular ore separation wheel is kept in a tilted position, forming a predetermined tilting angle with the vertical, is rotated at a predetermined speed to help the created negative draft to separate the heavy material(s) from a mixture of heavy and light materials fed into the circular ore separation wheel.

  • Patent number: 10350644
    Abstract: A system for identifying particular items in a stream of items and for deflecting that type of item from the stream to a different destination. In one embodiment, an LC resonant circuit including an array of coils is transversely disposed across the path and resonates in response to passing metallic items, wherein metal detection signals having an amplitude and a phase are generated. A graphical user interface enables user input with respect to an x-y graph defining amplitude-phase delineations and an ejection zone for the type of metallic item. A controller determines, for each generated metal detection signal, whether a corresponding metallic item is the defined type of metallic item and further within the defined ejection zone, and causes one or more ejectors to controllably eject the corresponding metallic item from the stream to a second destination.

  • Patent number: 10300510
    Abstract: A high-speed method and system for inspecting a stream of parts using at least one transparent traveling carrier of a conveyor subsystem are provided. The subsystem has a forward reach and a return reach. The method includes controllably receiving a stream of parts in rapid succession on the at least one traveling carrier and utilizing the subsystem to transfer the stream of parts in rapid succession to a part inspection station. The bottom surface of each part is illuminated through its traveling carrier with radiant energy when the part is located at the inspection station to generate reflected radiation signals which travel through its traveling carrier. A bottom image of each illuminated bottom surface is formed from the reflected radiation signals at an imaging location between the forward and return reaches at the inspection station. The bottom images are detected at the imaging location.
