  • Publication number: 20230201746
    Abstract: A filter plate assembly which is resistant to both wear and deformation caused by creeping, while facilitating maintenance thereof. A filtrate vat is provided that is formed on, and integral with the filter plate, in addition to a separate, replaceable vat liner. In this way, a rigid structure of the filtrate vat capable of resisting deformation may be achieved, while the vat liner separates the filtrate from the filtrate vat and the associated filter plate, providing wear resistance and facilitating maintenance. The present disclosure further concerns the filter plate and the filtrate vat.

  • Publication number: 20230191456
    Abstract: A screen medium of a mobile multi-deck screen is tensioned with a tensioner. A tensioning link engages and tensions a screen medium on a side thereof by at least two linear tension rods, when the screen medium side tensioner is installed to the mobile multi-deck screening device. An adjusting member causes for each of the at least two linear tension rods, a linear movement tensioning by the tensioning link the side of the screen medium above the two linear tension rods. A retractor disengages the tensioning link responsively to untightening the at least two tensioning rods. A screen deck, a screen and a mobile multi-deck screening device are also disclosed as well as a method for replacing a screen medium using the tensioner.

  • Patent number: 11679389
    Abstract: A retainer assembly for securing a mantle to a mainshaft of a gyratory crusher. The retainer assembly includes a headnut and a burn ring that are joined to each other prior to installation. The headnut includes a first and a second series of bores that each extend though the annular headnut. A series of jacking bolts are installed in the second series of bores and a series of connector are installed in the first series of bores. The combination of the headnut and burn ring are installed on the mainshaft. Once in place, the connectors are removed and a series of cylinders are positioned in the first series of bores. The cylinders are pressurized to create a gap between the headnut and the burn ring. The series of jacking bolts are rotated to maintain the gap and one or more shims can be positioned in the gap. The cylinder are removed and a headnut cover is installed to protect the headnut. During removal of the headnut, the cylinders can be reinstalled and pressurized.

  • Publication number: 20230173411
    Abstract: An outlet piece assembly for a horizontal plate and frame-type filter, such as tower press. The disclosure is based on the idea of providing the outlet piece assembly as having a base removably attachable to a filter press (e.g., to the filter plate or plate frame thereof), and a lid removably fixed to the base, such that an internal conduit of the outlet piece assembly running between a vat end and a discharge end is formed between the base and the lid. This enables a part of an associated filtrate vat component, such as the vat liner, to be received between the base and the lid, thereby ensuring secure sealing between these components.

  • Patent number: 11660606
    Abstract: A system for monitoring at least one motion parameter of the main shaft of a gyratory or cone crusher. The system includes a sensor, such as a magnetometer, positioned within close proximity to a magnetic element, such as a lifting lug, formed on a top end of the main shaft. When the main shaft rotates or moves vertically, the movement creates a change in the magnetic flux, which is sensed by the magnetometer. The change in the magnetic flux is sensed by the magnetometer and an output signal is generated. A controller receives the output signal and determines at least one motion parameter based upon the detected changes in the magnetic flux. In one embodiment, a permanent magnet can be the magnetic element or can be inserted into the lifting lug to enhance the magnetic flux changes caused by the rotational movement or vertical movement of the main shaft.

  • Publication number: 20230055796
    Abstract: An outlet cover with a first attachment pin fixed with respect to the outlet cover and having a radially extendable portion deformable upon by a radial force exerted from a hollow inside of the first attachment pin. The radially deformable portion prevents the first attachment pin from being withdrawn from an associated attachment hole, while allowing the first attachment pin to be compressed further into the associated attachment hole, thereby preventing a securing element from stripping any retaining surface, and thus increasing the longevity of the outlet cover. An associated filter plate, filter plate assembly and a filter are also concerned.
