摘要： 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.

摘要： A filter diaphragm for a filter plate assembly of a recessed plate-type filter, such as a filter press or a tower press. The diaphragm includes a sheet-like body having a flexible structure, and, at least on a side of the body, a plurality of distinct attachment studs to be inserted into corresponding distinct attachment holes of a respective filter plate for attaching the diaphragm to the filter plate. The attachment studs are arranged along a sealing region extending along a periphery of the filter diaphragm and extend in a direction perpendicular to the diaphragm body. The attachment studs are equipped with an opening extending through the filter diaphragm, between the opposing sides thereof. A diaphragm filter plate and -assembly, and filter are also concerned.

摘要： A fluidizing nozzle for introducing fluid into a fluidized bed reactor and a fluidized bed reactor. The fluidizing nozzle includes a nozzle tube limiting at least a part of a feed channel in which fluid is configured to flow, at least one fluid discharge opening arranged near a downstream end of the nozzle tube, and a pot-like hood, which sealingly closes the nozzle tube with a hood cover of the pot-like hood at the downstream end of the nozzle tube at which said at least one fluid discharge opening is provided. The feed channel is provided with a flow restriction element defining at least one flow restriction feed channel upstream of said at least one fluid discharge opening.

摘要： A mobile mineral material processing station has a mobile platform having tracks or wheels or a skids for supporting or forming a body that supports in line, in a transport configuration: a feed conveyor; a screen frame and a multi-layer screen; first and second exit conveyors; and a third exit conveyor on top of the first and second exit conveyors. The first exit conveyor turns from a transport position, under the third exit conveyor, to a first operation direction, onto a first side of the station, for operating the station, and back. The second exit conveyor turns from a transport position, under the third exit conveyor, to a second operation direction onto a second side of the station, opposite to the first side, and back.

摘要： A method and an arrangement for removing amine(s) from a thickener overflow of a mineral processing plant. The method includes supplying the thickener overflow to an electrocoagulation unit and subjecting the thickener overflow to electrocoagulation in order to separate at least some of the amine(s) as an electrocoagulation overflow and in order to form a residual process water as an electrocoagulation underflow, and removing the electrocoagulation overflow. The method is free of all of the following: a coagulant, a flocculant, an adsorbent and an additional flotation chemical.

摘要： A grate support element for supporting a grate of an open-ended grinding mill comprises an outer perimeter section, an inner section, and at least one vane extending between the outer perimeter section and the inner section. The grate support element further comprises a mounting flange at the outer perimeter of the grate support element configured to enable mounting of the grate support element to a shell of the grinding mill at an area of the shell not intruding to the grinding mill volume. The mounting flange extends outwards from the middle of the cross section of the grinding mill.

摘要： A grate support element for an open-ended grinding mill comprises an outer perimeter section, an inner section, and at least one vane extending between the outer perimeter section and the inner section of the grate support element. The vane is angled with respect to a plane defined by the outer edge of the outer perimeter section in such a manner that the inner section is configured to be provided outwards from the plane defined by the outer edge of the outer perimeter section, when the grate support element is mounted to the open-ended grinding mill.

摘要： A flotation arrangement for treating mineral ore particles suspended in slurry. The arrangement includes a primary line including at least two primary flotation cells, a first secondary line, and a second secondary line downstream of the first secondary line. In the arrangement, underflow from a secondary line is arranged to flow to the last of the at least one primary flotation cells from which the primary overflow was received, or to a primary flotation cell downstream of the last of the at least one primary flotation cells from which the primary overflow was received. The disclosure further relates a use of a flotation arrangement, to a flotation plant and to a flotation method.

摘要： A method for treating process water of a flotation arrangement, the flotation arrangement including a flotation arrangement including a mineral flotation line and a process water treatment arrangement for treating underflow of the of the mineral flotation line. The method includes the steps of a) dewatering underflow from the flotation in a gravitational solid-liquid separator; b) subjecting supernatant from step a) to cleaning flotation for collecting at least fine particles and residual flotation chemicals, for separating at least fine particles and residual flotation chemicals from the supernatant into cleaning flotation overflow, and for forming purified process water as cleaning flotation underflow; c) removing cleaning flotation overflow as tailings, and d) recirculating purified process water into the mineral flotation line.

摘要： An impeller and a diffusor is provided which are configured to be used in a flotation tank to enhance mixing of gas and slurry. The impeller comprises two opposing inlet ends and the diffusor comprises two opposing inlet mouths. The impeller is configured, when arranged inside the diffusor, to pump a bi-directional axial flow of slurry into the diffusor. Further, an arrangement using such diffusor and impeller for the use in a flotation tank to enhance mixing of gas and slurry is provided.
