  • Publication number: 20230417530
    Abstract: A wear sensor, a method for sensing wear occurring to an object, and an equipment subject to wear. A wear sensing system that includes the wear sensor and a measuring device for measuring an amount of wear occurring to an object. The wear sensor includes an electrical circuit having a sequence of discrete elements, each discrete element being capable to temporarily hold a digital data value. The electrical circuit is configured to sequentially transfer the digital data value from a first discrete element on a first edge of the wear sensor to subsequent discrete elements toward a second edge of the wear sensor. Each discrete element is capable of being electrically decoupled from the electrical circuit, sequentially in a direction from the second edge by action of wear on the wear sensor. A number of discrete elements in the sequence is reduced when wear occurs on the wear sensor.

  • Patent number: 11835160
    Abstract: A pipe flange coupling device, which is attachable in connection with a first pipe of a first pipe flange, having pawls engaging a second pipe flange of a second pipe. The pawls are fixed to a spindle retractable by a translation arrangement so as to pull the second pipe flange against the first pipe flange. More particularly, the translation arrangement is configured such that, when the flanged pipes are coupled and the pawls are retracted, a force exerted on the pawls towards the extended position is transmitted via the translation arrangement against a mechanical stopper. Moreover, the translation arrangement is biased such that the translation arrangement must work against this bias in order to extend the pawls and release the flanged pipes coupled to each other.

  • Publication number: 20230364531
    Abstract: A grid and a vat for a vat assembly of a vertical filter press such as a tower press is disclosed. The grid is provided with a topographical pattern engaging with a corresponding, inverse topographical pattern on the filtrate vat. The topographical patterns guide the filtrate flow towards a filtrate outlet and reduces the formation of vortices and turbulent flow of the filtrate, hence increasing the filtrate flow rate through the vat. Simultaneous, the topographical patterns improve secure attachment of the grid onto the vat, thereby allowing increased travel speed of the filter medium during advancement thereof. As a result, the cycle time of a filtration process may be reduced, and consequently, the overall capacity of the associated filter press is increased. A filtrate vat assembly and a vertical filter are also disclosed.

  • Publication number: 20230356262
    Abstract: A mobile mineral material processing plant is adaptively coupled to a screen module using an elongated coupling base that has first and second adapters to respectively detachably attach together a screen module, one or more exit conveyors and to detachably attach the screen module and the one or more exit conveyors to the plant. The first adapter pivotably couples to the plant on laterally moving the plant to engage with a first connector of the first adapter. The second adapter allows an actuator to lift the screen module with the coupling base so that the screen module pivots from ground about the pivotable coupling to an inclined operating configuration. The coupling base is angled to horizontally align a reject conveyor in the inclined operating configuration.
